Pinhole leaks, copper pipes.
 

Damn if I'm not having to replace yet a 3rd pinhole leak in about 8 months, with my water pipes. The pipes are only about 7 years old.

Should I just repipe with pvc or something ?

well pvc is ideal, what pipes specifically? Leaking at the solder joints or?

Are the leaks in the joints or in the pipe?

7 year old copper leaking? You must have some funky HARD water or something.

Yeah for sure, damn thats some serious mineral water you got there!
I think you need to find the common factor.. all close to water heater? Random locations etc etc?

Maybe the anode rod in your HWH is completely gone and the water is attacking everything.

Dont know enough to really help, but thats just not right.

The first 2 leaks were near each other at the far end of the house, furthest away from where the pipes come into the house. This recent one however is near the front of the house somewhere, have to get someone out to find it.

Are they leaking at the solder joints or at various places along stretches of pipe?

Water Chemistry
Faulty piping
Poor craftsmanship

Could all be possible issues.

I've been digging up info on the net, found it happening to a lot of people it seems. Some blaming it on EPA cleaner water regulations, eliminating a chemical in the water that used to protect the pipes, etc..

The first 2 were not at a joint, but in a stretch of pipe. I don't know about this 3rd one yet.

PVC would be ideal if you were setting up something new. Repiping your whole house would be a little more than a day project to say the least. :winkwink:

If you can find out exactly what the issue is there's lots of stuff you can put inline (sediment filters, stuff to change the ph, etc) and that's probably worth looking into.

If you do decide to replace leaky sections with PVC, and they're hot water sections remember the max temp for PVC is 140.

Replace it with Kitec... I got my house redone with it... awesome stuff :thumbsup

Time to replace that stuff.. 7 years is long enough.

My home was built in 2001 and uses a combination of copper, pvc and polyethelene. Fortunately, no leaks but i've still got my fingers crossed.

PVC is definately NOT the way to go. Each PVC joint has a potential for leaks down the road. CPVC is what is used for hot water, but Copper is always a better choice. There are new copper fittings that have the solder already in them, all you have to do is flux the pipe and you are good to go. Not much more than regular fittings and you don't have to deal with the solder as much.
