I've never heard of this to fix PVC pipe leaks

I thought I'd share this since collectively we do a lot of DIY repairs, and I'd not heard of Plast-Aid before.

I had a small leak for my rooftop solar pool heating right at the joint shown with the red arrow. Very little room to work with to repair and I anticipated cutting out the sections each side of the Tee replumbing it all with new fittings. I asked for advice on another forum focused on pool stuff and one of the suggestions was to try Plast-Aid.

I was a little suspect that this would work, but after watching this video, I ordered some and gave it a try.


It was a messy job, and a lot dripped out because it is runny at first but I kept adding more and more and eventually I had built up a enough of a joint repair where I thought it would hold.

And... SUCCESS ! This is after about an hour of curing in the sun.

It was not available local and Amazon's seller was out of stock so I picked an online spa repair site that met my sniff test and accepted paypal as payment and was pleasantly surprised that it arrived 3 days after ordering.

I've had some success pulling failed joints apart and regluing them but that looks easier. I hope it holds.

There is zero room to work on this fitting. It was already kind of sketchy because one side of the Tee was using an oversized coupler where it joins into the pair of 45s. This fitting was not straight and I think that is why it failed.

I hope it holds too. In the video, the guy cuts with a hacksaw a 3/4 to one inch cut into the PVC pipe right at the fitting, and then goes on to repair it. At the end He pressure tests it above 500 PSI. Max pressure for my system is around 30 PSI so fingers crossed.
 
Showed my wife this posting. Apparently she was well aware of this product. The plumbers would use it to make temporary repairs.
This was a large school district... 53 schools.
 
Good to know DanHoo. My house has ABS piping for drains, and getting ABS locally has become a challenge in the last few years, If I have any future issues, this stuff maybe something to consider.
 
Hi Dan,
Hey what pressure are you holding with that glue cap repair?
I think you could safely hold 30-40 psi with a simple “no hub” type connection (the connector for cast iron pipe) in this situation.

There is always a decent chance that a “glue cap” type connection will fail and normally that happens at the worst possible time or situation.

Anyways I hope this works out for you.
Cheers.
Andy.

In the video linked above he tests his fix at over 500 PSI.

my system, normal pressure is 18 to 20 PSI according to the gauge on top of the filter. I suspect the pressure on the outlet side of the filter is lower.

edit: I hope it keeps working too.

I hope my reply did not come across wrong.

I'm always looking for options. With the leak at the red arrow, repair had no wiggle room short of cutting out and re fitting more than I wanted to.
