I have a Blanco 157-081-ST Single handle, satin finish faucet that leaks. I'm trying to get to the cartridge but don't know how to take off the handle. I've removed a single screw on the handle body but it still doesn't come off and I don't know if there are other screws that need to come out. Any help, please? Thanks

minarl deposit bildup in the handol best to just replace the sprayer any hardwer store hose is still good only sprayer head needs replaced comen threds

Hi. To fix leak, replace cartridge in valve. To clean out drain, Clean out trap under sink.

Yes the leak is the washer. You can get a new washer at any hardware store. Just take the damaged washer with you and have someone at the store help you.

Here is the washer size according to the manual 20X12X2.5

Take the head apart and clean it and it should start working again.

Try this useful specs from Blanco ---->LINK .

You need to turn the water off under the sink. Disconnect the sprayer hose from the threaded shank under the center of the faucet body. Pull the spray head out of the faucet. Contact Blanco to receive your faucet parts free.

Hi, there are flexible water pipes that scew into the bottom of the tap, one of these could of come loose; try tightening, or the washer may need replacing.
Hope this helps

you can call or e-mail the company, if the faucet is the one in the picture it is a single cartdridge, turn of bith hot and cold water, take an allen wrench into the little plastic cover to remove the handle , unscrew the top cover or it might pop off, that there is either a large lock not or 3 screws holding down the cartdridge, take it out replace it put some faucet frease around all rubber gaskets then install it in the smae way it came out

You only need one small o-ring. If you put two of them it will not work properly and will mostlikely leak like crazy. If this helped please rate.

Somewhere around where the handle fixes to the tap should be a grubscrew of some kind undoing this will allow the handle to be removed this will give you access to the cartridge which can then be removed with the correct socket, obviously you will need to turn off the water supply to the tap first!!
