DIY PVC repair question

[stomachmonkey]

Lets say you had a 1 gallon plastic / PVC bucket.

It has a hairline crack around 80% of the circumference.

You can only get to the inside of it, no access to the outside.

How would you repair it?

Some requirements.

It needs to be absolutely 100% waterproof and leakproof.

Has to be 100% non toxic.

If you've not guessed yet yes, this is for my pool debacle.

We thought we found the source of the leak earlier in the week but it once again drained overnight.

Builder and I spent a few hours yesterday scratching our heads.

I suspected the problem was one of the two main drains.

Finally found the hairline crack in one of them.

No it cant just be caulked up.

The fix right now looks like jack hammering up the floor of my brand new haven't even had a chance for hotub sexy funtime with the missus yet jacuzzi.

Yes I want it repaired correctly and just wondering if anyone has a thought on in place repair.

My thought was caulk up the crack then get a thin flexible piece of PVC or other non permeable material to go 360 the full inside of the drain extending maybe an inch above and below the crack slathered in some strong adhesive to reinforce the structure.

Yes? No? Stop obsessing and let the builder you paid to provide a leak free pool deal with it? Drink more?

You're not gonna like it, but dig it up and replace section?

If I could clamp it, I would get pvc cement into the crack, (assuming you can get the crack open a bit) then apply clamping pressure.
Or just replace the damaged fixture.
Why did it crack? Misaligned?

I'd wonder about just using PVC cement, but I would be concerned that would just end up being temporary. There is PVC cement that is one part that can be applied if the environment is already wet. But I'm not sure how well it will work without being able to expand the gap and then press the gap firmly back together.

So, my thinking is
Would you like to fix it now and not know if the fix will last a day a month or a year
or
Would you like to fix it the hard way today and know that the fix should be as permanent as it could be.

JB Weld

Check with plastics suppliers, they may know of someone that does plastic welding. I've used the process to attach strain sensors to the polypropylene insulation of subsea oil lines. It works really well, quite strong.

A pic would help. I would likely sand it all with 60 grit and get some epoxy resin and some thin fibre glass woven matt and line the entire inside surface.

Well that's where we are at the moment.

That probably wont get started for a week.

Wife is out of town for the weekend so I figure, what do I have to lose?

I can't make it any worse since we are already planning to take a jackhammer to it.

It's literally a bucket encased to the rim in cement.

Can you access it straight on? What about an internal sleeve with PVC cement?

What I would do too. Never mess with it again. A new cheap plastic bucket is bound to fail again over time

Where is the crack in relation to the height of the drain?

What is the diameter of the drain?

Is it PVC for sure? or ABS?

You may get lucky, go to a local Home Depot or Lowes etc. and see if the have any buckets that can nest snuggly within the drain, cut off the bottom, cut of the top, get some PVC glue and sleeve the drain..

Or if a piece of PVC pipe OD closely matches the ID of the drain.... same idea sleeve it...fill the annular space with caulk ...

[gordner]

even if you get a bucket the same size, you can relieve it to fit inside and just epoxy the seam at the same time as the rest.

I would definitely line the entire surface to deal with the next crack before it inevitably comes.

[unclebilly]

Fibreglass bonds well to PVC. This is what is used on 24” PVC water line Tee’s when they make them.

I would use epoxy and fibreglass May instead of polyester resin.

[rusnak]

I would replace the whole thing. The problem with repairs is that if the bucket moves or the concrete settles, the crack will open up and you'll have to repair it again.

[Deschodt]

insert pipe of slightly smaller diameter and bond it over the crack (And the entire surface really), no idea if feasible. Like an internal sleeve ?

[cabmandone]

I think drink more is the solution.

[gordner]

Then he is guaranteed to leak more Cab!

[cabmandone]

But he'll care less!

My pool guy recommended this for a leaky fitting:

Powder with hardener. I’d grind it out and use this.

Well, actually I’d make installer repair and guarantee the repair.
