SOURCE: How do I replace the side spray base for my Blanco

Hello. The side spray base is held in place with a washer and a nut on the underside of the sink. Sometimes this nut gets a bit corroded and can be difficult to remove. Here is what you will need to do. Borrow or purchase a faucet wrench. These are available at all hardware stores, home depot, lowes. Also get a can of a lubricating spray called WD 40. This is sometimes a two person job so call a friend. One person under the sink and one above, use the faucet wrench to grab ahold of the nut surrounding the hose. As you are looking up at it it will come off by turning it counter clockwise. If it doesn't come right off spray it with WD-40 and leave it for 30 minutes while the penetrating oil does it's magic.
You will also have to unscrew the sprayer and pull off the little metal keeper that will keep the hose from sliding through the opening.
Once these things are done you will have removed the old base and you will be ready to replace it by reversing the steps. Regards, Joe
PS kindly rate my answer. thank you.

How do I replace the cartridge on my 157074R-ST. I'm a little handy, but I have a bad back. Can the repair be completed without going underneath the sink?

This is an easy job.

The only thing to do under the sink is to turn the water off.

The hard part is finding the replacement cartridge (Blanco #2408).

Once you do that, simply remove the handle (undo the set screw in the front, below the temperature indicator,) and remove the lock nut that holds the old cartridge in place.

Lift the old cartridge straight up and out, put the new one in its place, and replace the nut and handle. The whole job will take you ten minutes, from start to finish. (Remember to turn the water back on.)

I've attached a parts breakdown:

Cartridge replacement

Should be able to order new one at any plumbing supply. Remove handle, then with pliers pull out old cartridge, and push in new one till it seats, place handle back on.

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.

If the screw you have removed is a set screw then you shuold be able to remove the handle. If it has been on there awhile you may need to pry on it with the handle in the full open state. Use something that will not mar the handle.

I have a single handle blanco classic that is leaking around the base I have removed the handle and cartridge but cant figure out how to remove the sprayer to replace the seal

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.

How to replace cartridge on blanco single handle

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!!
