Leaking kitchen faucet delta saxony 473-sd.

IF CROSS THREADED YOU MAY HAVE TO USE TWO PIPE WRENCHES ONE TO HOLD FAUCET IN PLACE THE OTHER TO TRY TO UNSCREW IT MAYBE YOU COULD USE SOME WD40 OR SOME RUST REMOVEL SPAY TO GET IT LOOSE IF IT IS SO TIGHT THAT IT JUST WILL NOT BUDGE YOU MAY HAVE TO CUT IT AND BUY A WHOLE NEW FAUCET.

Usually these are located in the aerator section of the unit.

The answer is 35. What does this have to do with pluming?

Go to hardware where your faucet is sold and determine what screw you need. The red/blue dealy is just a screw cover.

Check the screen at the hose connection under the sink. Check the hoses for any large debris in them. Verify that the water pressure coming from the water outlets under the sink is good. There is obviously a restriction somewhere...you just need to locate it.

There should be a nut holding the plate on. What is holding the u-shaped plate up?? You can't tighten the faucet from above. Seems strange the nut disappeared.

if you know how take out the cartridge and clean it out.this may help,if not you may need to replace the cartridge.good ouck on your project.

This is a view from the underside of our sink. Is this what you were talking about? The steel plate is W-shaped (upside down in this case) and has a single nut larger than 3/4". It's almost impossible to fit a wrench up there to tighten it.
