Why do i have low pressure to faucets - Grundfos MQ3-45 1 HP Pressure Booster Pump

If you have pressure to the shut off valves then most likely your shut off valves are not fully opening, I would recommend you replace both valves, they build up water deposits in them a lot of the times. The other possibility is the faucet itself has a water saver filter built into it. A lot of the new faucets have water savers built into them now.

Before trying to get into the faucet it may be as simple as cleaning the aerator. Thiis video may not look like your faucet but it will give you the idea.

First thing to check is if it has a strainer on the spout that has debris. The second thing is if you have a sprayer attachment the diverter valve is a chronic problem with kitchen faucets.

it would only be aerator if hot and cold were low..what happened is when u shut angle stop off on hot water to replace assmbly..the washer on angle stop separated and is blocking the supply

Remove the spray head and point the hose into the sink drain. Turn the faucet on. If you have good pressure, cal American Standard for a free replacement spray head.
If you still have low water pressure without the spray head, ask them for a new faucet cartridge.
After replacing the faucet cartridge, if you still have low water pressure you will need to ask for a new faucet, possibly free if yours is still under warranty.

If you just installed it check to see if it has a water saving feature that in some homes and almost restrict all the water force

Try removing the aerator and handspray to clean out any debris that may have accumulated. After 8 years there could be quite a buildup if it hasn't been regularly cleaned.

Has pressure always been low? If faucet is new than there will be a flow restricter in the aerator. Most flow restricters can be removed easily. Some are a pain. Have you tried checking the pressure with the aerator off. That would tell you if the problem is there or in the valve.

lume build up. pull handle out and unscrew there should be filter inside take out and soak in a cup of lime away overnite rinse well and reinstall
