Hansgrohe Kitchen Faucet low water pressure

Almost certainly the hose. They leak from the bottom, cartridges drip from the top. That unit is discontinued.

The faucet is rated at 6.7L/minute (<2 gal/m) and I would expect that's a design of the cartridge. You could measure flow with spray head attached, then remove head (see link) and measure again to see how much the head reduces rate of flow. You could try removing the check valve(s) but not sure if that will work as it may leak.

check the strainer in the tip of faucet the screen my be stopped up if that does not help try removing the water restricting water saver in the screen assembly it can be removed allow more water pressure usually these usually screw off the end of faucet if it is a faucet with built in sprayer remove sprayer faucet head from the hose and remove it from end of hand held unit it will pop out

On the 35807801 there are generally only two causes of a leak. If the faucet does not seem to shut off and constantly drips it will most likely be the cartridge. This will be part number 92730000. If the faucet is leaking around the sprayer or below the sink the most common cause is the pull out spray hose. This will be part number 88624000.

I have had the cartridge replaced in my moen single handle faucet with sprayer in the end and now it turns off by itself. Any suggestions on the problem

it can be adjust take handle off and remove locking collar first turn water off,

it has a metal or plastic ball with a shaft for the handle it may have spun or a washer may be bad under it,

you can get a replacement at lowes or Home depot to replace it if this is the problem .

Water hammer: is a loud banging or clanging of the pipes usually occurring when a valve is turned on or off due to loose pipes.

Solution: Anchor the offending pipes to the wall. Buy water hammer arrestors. Also Lower the water pressure with a pressure reducing valve

Hope this tip Helps.

I have moen kitchen faucet # 7560 and water pressure very low. What should I do? We check water flow in pipe it is ok. I changed cartridge as well as pipe nothing help. Please let me know. thanks

start by making sure the valve that supplies hot water to the sink and dish washer is fully open. If there is low hot water pressure in any of the other kitchen/bathrooms, then trace the line to see where the pressure drops. If it is only in the kitchen, it should be an old valve, (causes restriction)Good Luck.
