Reverse osmosis water filter

I have a reverse osmosis water filter. The other day water production went from over a gallon of filtered water to 3/4 of a cup. We changed the filters thinking that may be the problem, but that did not solve anything. What else could be wrong with it?

Hi jennym123,

I'm Harvey the Master Plumber.

Your question is: You have a reverse osmosis water filter. The other day water production went from over a gallon of filtered water to 3/4 of a cup. You changed the filters thinking that may be the problem, but that did not solve anything. What else could be wrong with it?

This is a common problem. Can also be very frustrating. A small bit of debrie has been brought up by the flowing water and is stuck somewhere. As you can imagine this will restrict the flow. I would start with the on/off valve next to the cold water line first. Turn the water off first and take it apart checking for obstructions. Then work your way down checking the lines and any place you can. It's helpfull to have a bit of wire to probe with. If you turn it back on and the problem still persists then you missed it. Try again. Good luck.

Feel free contact me again!

need to change your filter cartridge. your water might be of poor quality and you could need another not so fine filter in front of the filter you have. this will also give you a longer life to the filter you have now. another problem could be that your aerator is blocked. it is found on the end of the spout where the water comes out. unscrew it and check that there is no dirt or foreign material here.

Since we fixed our dish washer, the water prssure in the kitchen faucet is very low. A friend told me to clean the filter. where is the filter, and what do I need to open in order to get to it?


filter screen is usually just under where the water comes out. Cover drain so any parts do not get lost down drain. Just unscrew it counter-clockwise to loosen it up. Remove screen and clean by flashing water in bathroom sink until screen holes are clear. then re-install and tighten in clock-wise direction. All done after you check that water comes out again.

The pressure on an EMPTY tank should be 8-10 psi. Be sure the tank is empty before checking the pressure. A good way to empty the tank is to connect a small air compressor to the air valve on the tank, open the systems faucet, and turn on the compressor. A bicycle pump works too....Just more of a workout:)

I have a white Franke fireclay sink. We also have very hard water despite using an undersink filter. The sink is part of a new remodel and despite little use so far and lots of wiping, the water spots seem...


The best product I have found to remove water spots is a product called A-maz water stain remover in a 14 oz tub. There is no magic "wipe on,wipe off" product that I have found. Initially it is a little labor intensive but this is amazing stuff and can return your sink to its original luster.

This company also make a sealer but I have not tried it. A couple of alternatives might be Rain-X or Maguires auto wax. The concept here is to put a barrier down that will seal the pores of the sink and make it easier next time to remove the spots. My favorite is Maguires about every 3 months. I have provided a link below to the A-maz web site where you can find a distributor nearest you.

There is a blue cap on the body of the white pressurized water tank. Twisting off the blue cap, you will see a air nozzle - similar as those on the tire. You need to pressurized the tank to 60 PSI. I spend hours to figure out this solution on my own system.

Are you sure the spray handle is allowing the valve to open enough to allow enough water through? The problem it seems like is physical or mechanical. I am assuming you get good water flow through the faucet itself.

GE smartwater under sink filter shuts down after changing filter


run water through the unit with no cartridge in place. Then check the filter to be sure it does not have an obstruction in it. Finally, replace the filter and your pressure should be fine. Good luck.
