We have a Pfister Kitchen Faucet with a Pull Down Spray. It is a water saver unit and had only about a quarter inch tubing inside. The water pressure is very slow with this faucet. Any suggestions to improve it?
The 1/4" inlet line is typical of all faucets and has been for decades. The "water saver" portion is mostly in the aerator. You can remove one of the restrictors or enlarge the orifice slightly, before you do, however, make sure that the supply valves under the sink are fully open minus 1/4 turn.
If the low pressure is a new problem, you may have a blockage somewhere.
What type of pipes do you have in the house? copper, steel, pex or cpvc?
It's only been a problem since installing the Faucet. We had galvanized Steel but it was changed to PCV Pipe under the house. Under the sink it is flexi steel. We live in South Texas where it normally doesn't freeze.
Here's a quick and easy one step test you can run:
1. Turn off the angle stops under the sink and disconnect the supply flex lines from the faucet.
2. Using a bucket to catch the water, turn one angle stop at a time while holding the flex, and see if you get good pressure at this point.
Report back with your findings to determine the next step.
If at any moment you feel you can't do it or it's too hard, stop and get a plumber. You don't want to end up with a flooded kitchen.
All you had to say was galvanized pipe.
Odds are, when the water was shut off to change the faucet, it broke corrosion loose which is now plugging up the line. Large flakes can clog the main line into the faucet, more than likely it is small flakes clogging the aerator. Remove the aerator first and run the faucet. Also, rinse the aerator and it's pieces well to remove any rust particles that can be causing a problem. Reassemble the aerator and reinstall it in the faucet and see what that does.
My husband already did the test with the flex lines. Good pressure, until the faucet is reconnected. We've removed the faucet head and cleaned it several times but it still has low pressure.
There is a vacuum breaker in the head. You have to remove it and clean it out. It should be were the hose connects to the head. Disregard my last statement. There vacuum breaker is in there cartridge. Here is a link to the faucet break down.
There may be leakage or blockage in the pipes.You should call a leak detection service and check all your pipes.Nowadays leak detection services uses new technologies in finding leakage and repairing it.They will take very less amount of time so call them and they can surely solve your problem.
were the pipes flushed with the aerator off?
was the flow rate checked with the aerator missing?
