I have done a few of all kinds of water leaks in the ground like maybe 1000 plus and every time I came across one there is one thing for sure , water coming out of the ground and with wet ground, it makes it easy to dig unless your in very clay ground. Lets say you dig about 2' or even more and you find a pipe with a leak ( 90% they are a fitting or a T or a valve) and since you are already sick of digging in the mud so you make a 1' by 1' hole around the leaking pipe. Well if the leaks a hole in the pipe there is no way your going to cut the pipe off and slip a coupling on it and push the pipe together so that's why someone came up with a slip coupling which slides in and out but holds pressure and if you have a hardware store just maybe they might have one in stock in YOUR SIZE OF PIPE! If you are working with PVC MAKE SURE and I mean very SURE that the fittings & pipe are dry before applying primer and glue because if you have water on the pipe or fittings the joint will not hold and if it does check back 2 hrs later. The same can be for a T or valve just you are going to dig more and you should only need one slip coupling because the rest of parts should slip into place.

Be more informative on "over heats". Is it being driven along time before it over heats? Is the guage showing hot but not boiling out the radiator, is there steam coming from under the hood, is there a sign of leaking under the passenger side dash or under the firewall on the ground, have you had the thermostate replaced, is the water pump leaking?
If you have a drain leaking under your sink, you should first turn off the water supply to the sink. Then, try to identify where the leak is coming from. It could be a loose connection or a damaged pipe. You may need to tighten the connections or replace the damaged parts. If you are not comfortable doing this yourself, it is best to call a plumber for assistance.
