Water Control PS-5 Troubleshooting And Maintenance Manual

PS-5 Reverse Osmosis Drinking Water System

Troubleshooting/Maintenance

Maintenance

- 4 stage membrane/filter cartridge should be changed every 1-2 years
o Decrease in system production and increased TDS output are signs the cartridge needs

to be changed

- Inline carbon filter
o Should be changed every 6-12 months

Troubleshooting

- #1 Problem – Water Leaking Out of Air Gap
o System is doing what it is designed to do

 Air gap is typically required by code

• Creates separation between RO unit (backflow prevention)

 Water that backs up in the drain line goes out of air gap rather than back to RO

unit.

o Causes

 Installation errors

• Is the drain saddle installed nice and straight?

• Does the drain tubing that connects from the air gap on the faucet to

the drain saddle have any loops or dips in the line?

o Should be installed as short and straight as possible in a

downward path.

 Obstruction in the drain tubing between air gap faucet and drain saddle

• Disconnect the tubing and blow through it in either direction to make

sure it is clear.

PS-5 Reverse Osmosis Drinking Water System

- A Noisy Air Gap Faucet

Troubleshooting/Maintenance

This can be caused by the air gap faucet, the location of the drain saddle, a restriction in the
drain tube, or water pressure in excess of 85 psi.
Some noise is caused on start-up after filter changes by air being purged from the system. Once
the air is expelled from the unit (usually after about 5 minutes) this noise should subside.
Although the air-gap faucet inherently makes some noise, this can be amplified if the water
running from the drain saddle splashes into the water in the sink trap. This noise can be reduced
by either moving the drain saddle to a greater height, or by securing a fishing line through the
drain saddle and down into the sink trap, allowing the water to run down the side of the drain
pipe.
A restriction in the drain tube can be caused by debris from the dishwasher or garbage disposal.
The tube can be unclogged by removing it and cleaning it with a wire or coat hanger.
If the water pressure is above 85 psi, a pressure regulator may be required.
