Hi, this is Nicholas Iarocci, The Home Source Guy, President and Owner of Source Development Inc., a residential and commercial construction company in Garnerville, New York and this is troubleshooting a leaking sink. It's kind of a loaded question. There's a lot of possibilities that could lead to a leaking sink so lets start off with the supply lines and the water supplies. Now they're under constant pressure so if you notice a leak that's present as a constant meaning not so much when you actually use the sink or trap that you can't visually see you know it's coming from the water supply sides which are under pressure, right. So the first leak that could, we could discuss that might be causing you a problem is from the valve. Very often these valve stems just get loose from contraction and expansion, from age. Maybe the, the gas gets through the o-rings, deteriorate and they have to be repacked or replaced. So you try tightening the retention nut on a supply valve. Another thing is that these are no burst pipes but you can have ferrule and nut applications. That's a solid pipe, a rigid pipe, and you might be getting leaking from that. So you can loosen it up, apply some you know sealant or some silicone lube or something to try to stop that from leaking, if not totally replacing the whole system. At the faucet where the supply tubes attach to the faucet there's a retention nut so sometimes they get loose so there's a basin wrench that you can use or some channel locks if you can manage it to get up inside and give them a little tightening. So this fits around the lock nut and you tighten it. You could be developing a leak at the base of the faucet or at the stem valves, valve stem excuse me and they can be causing a leak which means that you know you'd have to get new gaskets at the faucet and stem. Another leak possibly is the spray. Believe it or not if this is loose or it's leaking here it'll trickle down the pipe and you know this pipe would actually form a drip and you get leakage there and you might not be able to spot it so you want to look at the hand spray too. Now lets move to the drain pipes. Those would be noticed when the sink is actually used and not a constant drip where you know you see dampness there all the time. This is plastic plumbing. If you had brass or copper or any form of metal galvanized or something like that. You'd have to make that there's no rot present and if there is you'd have to replace the pipes. Essentially if you do have plastic and you notice that it's leaking you could just try finger tightening it at first and then if not take the joints apart, you can add sealant to them or silicone lube, plumbers grease to try to alleviate the problem, if not you could try replacing the pipe, piping as well. And that was troubleshooting a leaking sink.
