Leaks into sink when turned on - Dishwashers

I think you should identify the problem at first)

1. A pressurized water hose leak
These will be really obvious - they'll be spraying pretty much constantly and creating a big mess.

2. A leak in the drain line
These will only become apparent when you turn your tap on and let the water drain away.

3. A faulty sink drain seal
If a leak doesn't appear in either case, try filling the sink with water, then let it drain away. This would suggest the issue is your drain seal.

A little bit of observation, trial and error should help you to work out which one of these issues is causing your leak.

In any situation you can buy a new sink - Best kitchen sinks

make this steps and fix it. God bless you
f a faucet leaks, replace seals and gaskets . If a shower head leaks, create a better seal or replace seals .
If a sillcock wears out, replace the washers .
If a compression faucet drips from the spout, replace the washer and/or the seat .
If a faucet leaks from the handle, replace O-ring(s), replace the packing washer, tighten the packing nut, or replace worn packing, depending on the valve type.
If a ball or cartridge faucet leaks from the collar, replace worn O-rings .
If a disk faucet leaks around the base or has reduced flow, replace cracked or pitted disk assembly or worn inlet seals
If there is water under the sink, tighten the faucet-set locknuts under the sink. You also can replace putty or a gasket, replace a worn faucet, or replace leaky supply tubes .
If the aerator leaks around the edge, replace the washer in the aerator
If the spray hose leaks or has reduced flow, replace the O-ring on the diverter valve, replace a worn washer at the base of the spray head, or clean the diverter valve and spray head

turn off the hot and cold water supply, place a container under the sink where the hose meets the Sink mixer.
release the pressure from the tap by opening the tap to let the water out.
use a suitable tool to undo the flexible hose from the underside of the tap, there should be a small "O" ring on it which you will have to replace as the "O" ring is possibly the cause of the leak.

leaking around handle?Turn water off under sink.remove handle,cover plate,unscrew valve stem assembly,and turn the two pieces apart to expose o ring,and replace

I have a Geyser GF8 that also leaks at the turning joint. Anyone know how to dissamble one of these faucets?

hello , usually there will be water supply lines coming in from behind the wall area and if it isnt leaking at the supply valve it self then you may need to open up the wall area behind the sink and find out what is leaking it depends on what type of pipe is used most likely you have cooper tubing and sometimes these tubes after a while may leak or form small holes or it may be a leak at a soldered joint remeber there are 2 lines one for hot one for cold and you can turn the off by shuting off your water at the main valve then repair the leaking area.

well if he is afraid then you take a chanel lock plier and go under the sink and titen it

ok if you go to real plumbing store i do not know where you are but they have the "washer"{ gasket } you would take out the sink only slides in to drain it is pretty tite replace your gasket and all new again

THE PART YOU ARE TALKING ABOUT IS CALLED DRAIN TAIL PIECE. THE DRAIN YOU CAN REMOVE BY LOSENING THE NUT UNDER THE SINK WHILE SOME ONE HOLDS THE DRAIN INSIDE THE SINK FROM TURNING THE OART KEAKING IS CALLED A SPUD GASKET WHICH SEALS THE DRAIN TO THE SINK

No matter what type of sink you purchase, the drain and water-supply connections are generally installed in the same way. Hand-tighten a female adapter onto the drain stub-out at the wall. Slide slip nuts onto the drain arm and the sink's tailpiece. Fit a P-trap in place and tighten the slip nuts by hand. Connect flexible water-supply tubes onto the faucet's tailpieces, and route them to the shut-off valves. Tighten coupling nuts with an adjustable wrench. Remove the faucet aerator, turn on the water, check for leaks at the shutoff valves, and then turn on the faucet to check for leaks in the drain assembly. Replace the aerator.
