Pre-installation checklist
Our pre-installation guidelines are detailed on the following pages, but some of
the key “do’s and don’ts” are highlighted below:
Do’s
Locate the pump next to the hot water
cylinder OR no further than 4m away in
22mm pipe work
Allow 100mm on all sides for ventilation
Ensure pump is protected from frost
If servicing two or more bathrooms, cold
water supply to the cylinder must be in
28mm pipe work
Ensure adequate cold water storage
(50 gallons/bathroom, 80 gallons for one
bathroom and one en-suite)
Cold water supplies to the pump must
be taken from the opposite side of the
cold water storage tank to the cold water
mains inlet
Multiple cold water storage tanks must
be linked in 28mm pipe work and the
bottom of the tanks must be at the
same level
Hot water supply to the pump must be
via a Salamander approved method
AV couplers must only be finger tight plus
one quarter turn
The maximum static head should be
10m (equivalent to 100kPa/1.0 bar
pressure) – only exception are the RP50TU
and the RP55SU which is 5m (equivalent
to 50kPa/0.5 bar pressure)
We recommend the pump is activated
for at least 5 minutes every 4 weeks for
the right pump variation only. The right
pump universal automatically activates
periodically to prevent sticktion
Don’ts
Never fit the pump to the cold
water mains
Never fit the pump to communal risers
Never use a shared water supply
Never put a non-return valve (NRV),
inverted loop, restrictive balofix or an air
vent on supply pipe work to the pump
The hot water supply to the pump must
not exceed 60ºC
Never twist the anti-vibration (AV)
couplers or bend more than 35º
Never use mechanical tools to tighten
coupler nuts as this may cause damage
and will invalidate your warranty
Never use jointing compounds,
Boss White, Hemp or steel wool
Solder fluxes must not come into contact
with the pump or AV couplers
Never install in a bathroom unless in an
enclosed space and access is only possible
with an appropriate tool
Never pump directly to or from another
pump
Never connect to a secondary return
tapping on a hot water cylinder without
the use of a dip tube into the cylinder
BEFORE INSTALLATION OF YOUR NEGATIVE HEAD
PUMP:
Please fit the pressure vessel, if packaged separate to
the pump. Use the ½” flat rubber washer in the ½”
brass connection on the top of the pump junction
box. Screw the pressure vessel into the connection
hand tight.

PumpWise and warranty
1. Location of the pump
The best possible location for the pump is
at or near the base of the cylinder at least
600mm below the bottom of the cold water
storage tank. Where it is not physically
possible to locate the pump next to the
cylinder, the pipe run from the hot water
cylinder to the pump must not exceed 4m in
22mm pipe work.
1.1 Cooling and ventilation
The pump should be placed in a position
where there is an adequate air flow to cool
the motor and separated from any other
appliances that generate heat. It should be
installed in a clear space allowing 100mm
additional space at each side, the ends and
top of the pump.
1.2 Frost protection
Loft mounted pumps must be protected
from frost damage.
2. Hot and cold supplies
to the pump
Never fit the pump directly to the cold
water mains.
Never fit to communal risers (e.g. block of
flats) or secondary circuits that are pumped.
The pump must be fed by exclusive hot and
cold water supplies (i.e. not shared with other
services) and in 22mm pipe work (Note: for
the RP50PT and RP55PS a maximum of 2m of
15mm inlet pipework direct from the cylinder
to the pump).
The hot supply pipe work should be a
maximum of 4m from the cylinder in 22mm
pipe work.
All up and over pipe work must be vented at
the highest point on the outlet of the pump
and a non-return valve (NRV) may require
Please follow these installation instructions carefully. Failure to install your pump in
accordance with these instructions will invalidate your warranty.
fitting to the hot outlet only (Note: this is
only for the RP50TU and RP55SU).
2.1 For pumps positioned above
the hot outlet, hot water
cylinder or in a loft
An anti-gravity loop (AGL)of at least 400mm
(ideally using swept bends) must be used
when the pump is sited above the dome
of the hot water cylinder as it prevents air
tracking up into the pump chamber and
back siphoning of the water, again, creating
air in the pump chamber.
An approved side or top entry flange must
be used in these circumstances for the hot
water connection to the cylinder, with the
Essex or alternative side entry flange being
the recommended method of connection.
If the pump experiences aeration or low
pressure as a result of poor flow to the
pump with the use of a top entry flange,
a side entry or Essex Flange may become a
requirement.
2.2 Cold water storage
Ensure that the cold water storage capacity
is adequate for all of the household
requirements (minimum 50 gallons/227 Litres
per bathroom, 80 gallons/385 Litres for one
bathroom and one en-suite shower room).
Ensure the cold water supplies to the cylinder
and the pump are taken from the opposite
side of the cold water storage tank from the
cold mains inlet.

2.3 Hot water requirements
The stored hot water temperature must not
exceed 60ºC (see page 17, Stored hot water
temperature).
The hot water supply to the pump must be
via a Salamander approved method:
The best hot connection from the cylinder
is either
• A 3⁄4” NO STOP ESSEX FLANGE. See
Figure 3 or
• Alternatively a Salamander S flange or
other approved top entry flanges. See
page 15/16.

3. Anti-vibration couplers
(Hoses)
The anti-vibration (AV) couplers are designed
to limit the transfer of pump vibration to the
associated pipe work. All Salamander AV
couplers are ¾” BSP x 22mm push fit with
built-in isolating valves. Note: the RP50PT
and RP50PS are supplied with 15mm
couplers with isolating valves on the inlets
and outlets.

5 Electrical requirements
The pump must be connected to the
electrical supply using the mains cable
with the attached plug. This plug must be
connected to an accessible socket that has
been installed in compliance with BS 7671
(I.E.T. Wiring Regulations). The plug must be
accessible at all times.
The pump must not be installed in a
bathroom unless it is installed in an enclosed
space accessible only with the use of a tool.
If the supply cord is damaged, it must be
replaced by the manufacturer, its service
agent or similarly qualified person in order to
avoid a hazard.
Higher rated fuses must NOT be used.
Fuses should be as per the table below:
Each single pump is supplied with two
couplers; one angled and one straight.
The angled coupler should be attached to
the pump inlet (on the side) and the straight
coupler should be attached to the pump
outlet (on the top).
Each twin pump is supplied with four
couplers; two angled and two straight.
For all pumps, the inlets are on the side of
the pump and the outlets are on the top of
the pump.
The AV couplers MUST only be tightened
to finger tight plus one quarter turn.
Mechanical tools must NOT be used to
tighten coupler nuts as this may cause
damage which will invalidate your warranty.
4 General plumbing
The installation must comply with the
relevant requirements or local by-laws.
The pump MUST be mounted upright (shaft
horizontal, not screwed down).
Jointing compounds, Boss White, hemp or
steel wool MUST NOT be used. Solder fluxes
must not come into contact with the pump
or AV couplers.
The maximum static head should be 10m
(equivalent to 100kPa/1.0 bar pressure)
with the exception of the RP50TU where
the maximum static head should be 5m
(equivalent to 50kPa/0.5bar pressure)
The plumbing installation must comply
with “The Water Supply (Water Fittings)
Regulations 1999” and “BS EN 806-4:2010”
buildings regulations.

Figure 11: Positive head
Negative head systems
Negative head systems exist where no
natural flow of water goes to the outlet
because either the outlet, or the pipework
to the outlet, is above the height of the base
of the cold water cistern. Most instances
of negative head systems occur in loft
conversions or where the cold water cistern
sits on the joists in the loft. If the distance
between the bottom of the cold water
cistern and the highest point of the system
after the pump is 2 feet (610mm) or less,
it is also possible that a universal pump will
be required. Salamander’s universal range
of pumps activates the pump automatically
even where no natural flow exists.
Negative head is also needed for electric
showers, dishwashers, washing machines or
where pumped hot water meets mains cold.

• Flush inlet pipework and carefully fill
pump with water by discharging water
from the outlet flexible coupler into a
container.
• Fit pump inlet filters.
It is CRITICAL to discharge water through
the pump into a container using natural
flow before connecting the pump to
outlet pipework in order to ensure
the air has been discharged from inlet
pipework and pump chambers. This
will not happen if the outlet pipework
is connected to the pump. The best
method is:-
Figure 19
• Open shower mixer valve/system outlets
to maximum hot and cold to check the
natural flow (unpumped) flow of at least
1 litre per minute – positive head systems.
• Open hot water outlets fully for
5 to 6 seconds and then turn outlets off.
Then open cold water outlets fully for
5 to 6 seconds and turn outlets off. If
flow is poor and inconsistent repeat
above steps until flow is steady.
• Repeat 2-3 times.

Cold water supplies and storage
Recovery of cold storage
The typical recovery rate of a 1⁄2 inch high
pressure part II BS1212 ball valve is:
100 kPa (15PSI/1.0 bar) 0.97 galls/min 4.41 l/min
200 kPa (30PSI/2.0 bar) 1.34 galls/min 6.11 l/min

400 kPa (60PSI/4.0 bar) 1.94 galls/min 8.82 l/min
Aeration of pump and cylinder
from a cold water storage tank
This occurs when the incoming cold mains
ball valve is positioned above the cold feeds
to the cylinder and to the pump – aerated
water is drawn into the pump as illustrated.
Figure 20: Aeration
Vortex
Reposition

Outlets to
pump
The bottom of the cold
tank MUST be checked
and cleaned of debris
Chronic aeration of the pump occurs when this
problem is combined with inadequate storage
capacity and/or when the volume of water
drawn by the pump and other services exceeds
the refill rate and creates a vortex which draws
air and possibly debris into the pump.
Cold storage usable capacity
The usable capacity of cold storage is easily
calculated as the capacity of water in the
cold tank above the cold feeds to the
cylinder, the pump and other outlets –
see formula.
Formula for calculation on rectangular
tank:
Depth (15”) x width (23”) x length (36”)
= 12,420 cu inches
Volume cu inches (12,420) x 0.01639
= 203.56 litres
Volume litres (203.56) x 0.22
= 44.78 gallons.
Formula for calculation on circular tank:
Depth (15”) x radius (17”) x radius (17”)
x 3.142 (Pi)
= 13,621 cu inches
Volume cu inches (13,621) x 0.01639
= 223 litres
Volume litres (223) x 0.22
= 49 gallons.

Water starvation protection, pipework arrangements and
stored hot water
Water starvation protection
In systems where it is absolutely not possible
to increase the usable cold water storage
capacity to meet the increased demand
of a pumped system; a water starvation
protection unit (WSP) may be considered.
The WSP is a Salamander level switch which
must be positioned 102mm higher than the
highest outlet from the cold water storage
tank. When the water level drops too far the
WSP will switch off the pump until the cold
water storage level is recovered.

Shower head size vs bar pressure
The size of a shower head dictates the bar
pressure of the pump required to deliver the
expected performance of the shower.
For pumps positioned above
the hot outlet on the hot water
cylinder
An anti-gravity loop (AGL)of at least 400mm
(ideally using swept bends) must be used
when the pump is sited above the dome
of the hot water cylinder as it prevents air
tracking up into the pump chamber and
back siphoning of the water again, creating
air in the pump chamber.
An approved side or top entry flange must
be used in these circumstances for the hot
water connection to the cylinder, with the
Essex or alternative side entry flange being
the recommended method of connection.
If the pump experiences aeration or low
pressure as a result of poor flow to the
pump with the use of a top entry flange,
a side entry or Essex Flange may become a
requirement.
Shower head diameter Bar pressure
Up to 5cm 1.5 bar (150 kPa)
5-10cm 2.0 bar (200 kPa)
10-12.5cm 2.5 bar (250 kPa)
More than 12.5cm 3.0 bar (300 kPa)
Please be advised due to lack of cold water
storage with Elson and Fortic (type) tanks,
our pumps may not be suitable.
It is advisable to contact PumpWise before
installing the pump on 0191 516 2002,
otherwise it may affect your warranty.

Warix flange
A The Vent connection MUST be from side
in Warix Flange.
B The supply connection to the pump
MUST BE FROM THE TOP of the Warix
Flange via a 22mm compression elbow
and thereby avoid inverted loops.
C In systems where there are one
bathroom and an en-suite shower.
Or two or more bathrooms the cold

Inverted loops
An inverted loop in the supply pipe-work
to the pump, particularly on the hot side as
illustrated; is likely to:
• interfere with the initiation and smooth
operation of the pump.
• restrict the supply water to the pump and
risk internal mechanical damage.

Water hammer protection
Water hammer most commonly occurs in
systems where there are long pipe runs
supplying solenoid activated appliances e.g.
washing machines or outlets with quick
acting/turn taps/ valve(s). The harmful effect of
water hammer shock waves can be cushioned
by fitting a pressure vessel unit, into the supply
pipework as close as possible to the outlet
from which the shock waves are originating.

Pump hunting protection
In negative head systems all the discharge
pipework after the pump is pressurised. In
such systems there exists the possibility the
pump will hunt ON-OFF-ON etc at intervals.
This will happen:
• if all outlets are not fully closed
• if there is a leak at a connection
• if boosted toilets are not fitted with
equilibrium ball valves
• or as residual hot water contracts in long
pipe runs.
The irritating effects of hunting are
cushioned by the pressure vessel which is an
inbuilt feature of the Right pump universal
range.
Stored hot water volume
In calculating the volume of the stored
hot water requirement it is important to
consider:
• number of bathrooms, with particular
attention to the size of the bath
• number of persons in household
• time spent in shower e.g. 10mins in a
5 gall/minute shower will use up 50
galls/227 Litres of the cold water storage
capacity approx 60% of which (30
gallons/136 Litres) will be hot water from
the cylinder.
Stored hot water temperature
Extract from BS5546:1990 (Current)
“The mean temperature of the stored water
should not normally exceed 60°C and in
a combined central heating and domestic
hot water system it is recommended that
the stored water temperature is controlled
independently from that on the primary
circuit”.
Extract from BS6700:1997
“Under normal conditions the
temperature of stored hot water should
never exceed 65°C. A stored hot water
temperature of 60°C is considered sufficient
to meet all normal requirements and will
minimise scale deposits in hard water areas”.
Effective control of stored hot water is simply
achieved by use of a cylinder thermostat and
zone valve or direct acting thermostatic valve
(e.g. tapstat).
In systems where the stored hot water
temperature is not controlled eg Aga solid
fuel appliance or very crudely by the boiler
thermostat, use a HWS Blending valve
controller.
HWS Blending valve controller
The HWS Blending valve controller is
designed to protect booster pumps in
systems where the temperature of the stored
hot water is uncontrolled.
