Customer Question
I have a GE reverse...
I have a GE reverse osmosis water filter(PNRV187). It started to malfunction and I found the bladder to have ruptured. I replaced it and it is functioning again but the yield is now less than 2 quarts when before a full tank would yield about a full gallon. I also wonder if the tank doesn't need to be re-pressurized and how much? Please advise. Thanx. PUP.

Empty all the water from the tank Deflate tank to reach 7 PSI air pressure. You can use a standard air pump similar to a bike pump Do not over inflate and damage the air bladder.

 

There are several other reasons, but this is a start, since you say the pressure is a little high. Below is a chart of things that can cause issues that you have. I would start with the tank since that is whats been changed recently.

 

 

Feed water valve is plugged or closed.Open valve or unclog.
Sediment/Carbon prefilter or Carbon Post Filter is clogged.Replace Filters.
Low incoming water pressure.Incoming water pressure must be above 40 PSI. Install a Booster Pump or Permeate Pump.
Reverse Osmosis Membrane is fouled.Make sure incoming water pressure is within operating limits. Make sure drain line is not clogged. (See High TDS) Correct cause of fouling and replace RO Membrane.
Air pressure in holding tank is incorrect.Empty water from holding tank. Air pressure in valve stem should be 7 PSI.
Air Bladder in Holding Tank is ruptured.Replace Holding Tank.<--- you already did this.
Holding Tank valve is closed.Open valve.
No water to drain. Drain Flow Restrictor is clogged.Replace Drain Flow Restrictor.
No water to drain. Air Gap Faucet is clogged.Clear or replace Air Gap Faucet.
Check Valve on RO Membrane Housing is stuck.Replace Check Valve.
The Automatic Shut-Off Valve is Malfunctioning.Replace Automatic Shut-Off Valve.

Unfortunately, there were no "exploded" views of the filter. I did however find a video which i sent a link to.
