How to remove the water flow limiter on a Grohe kitchen faucet.

You may need to remove the Grohe flow restrictor from the kitchen faucet if it's making it hard for you to work by taking too long to rinse dishes or fill the sink.To make sure your Grohe kitchen faucet flow problems are actually caused by the restrictor, you need to take a few easy steps.

If you have a Grohe kitchen faucet with low water pressure, the culprit may be outside of your home.The water flow may not be increased if the water supply is delivering less than 40 psi.The well pump may be on its last leg if you have a well.Water valves that are partially open may be the cause of low water pressure.

If you have a check valve on your kitchen faucet, you're good to go.To check the flow, simply remove the spray head and turn on the water.It's time to take a closer look at the spray head if the water flow is heavy.

Attach the check valve to the spray head with a screwdriver.To remove debris from the check valve, flush water through it.The old check valve should be replaced if you can't remove all the debris.

The flow of water through the spray head will be restricted if the aerator is dirty.Aerators have a mesh screen, mounting runs and a water flow restrictor.You can either clean or replace the screen and restrictor to increase the water flow.The end of the faucet spout is connected to the water flow restrictor.

The Grohe faucet, such as the F7 model, may come with a wrench that can be used to remove the aerator.You pop out the ring after you insert the tool between the aerator and ring.To remove the aerator, use the other side of the wrench to insert it into the spray head.

You can use pliers to remove the aerator if your Grohe faucet did not come with this wrench.To protect your faucet's finish, cover the area where you'll use pliers.Once you're able to remove it by hand, turn the aerator clockwise.
