Can cracked PVC be repaired?

[jwhouse]

Unless the flow switch is in a place that would require the glue to be put on it, I would leave it in. If you will end up with glue on the flow switch without removal, I would take it out.
As for the hose clamp, yes, leave it on.

Hope it works out for you. Will be a cheap temp fix with very little labor involved so even if it doesn't work, the worst case scenario would be that you have to replace the collar anyway.

Let me know how it turns out.

Thanks.

While you were posting, I added this question;

Do I need to use PVC cleaner before applying the glue (like you would when connecting PVC pipes)?

I doubt it will matter for this.

Thank you everyone for all the great suggestions. I'll let you know how it goes.

I found this:

Says it will fix leaks in PVC.

Anyone have any experience using this?

I have never had any putty epoxy last in a pressure side leak.

I have found only one product that works to repair PVC and stands up well to pressure side leaks. It is called Plast-aid. I have used it successfully several times now and have not had it fail but it does take a bit of practice to get used to. It cures in about 15 minutes to repairs are fast.

Their website has some excellent demo videos of how to use it.
The nice thing about it is that you can apply it as a glue or a putty so it can fill a crack. My only advice is use it outdoors if possible since the smell is really strong until it cures.

Interesting... That looks like it might work (apparently, it does). The putty stuff I doubt seriously but this plast-aid appears to be a filler and bonding agent and filler all in one. I may have to order some and give it a whirl myself.

Thanks. I'll check that out.

I also did a Google search and found this:

3M 08101 Structural Adhesive worked for me for PVC pressure piping. It's urethane, not epoxy. In shear adhesion test with rigid PVC,
the PVC breaks before the adhesive bond (2000 PSI).
For even more strength, fiberglass cloth can be embedded in the patch. I patched our sand filter base which was broken into 3 pieces and used fiberglass mat for reinforcing.

Wear disposable gloves, and plan your application, because it sets rapidly.

If you have a friend who is a pipefitter, most outfits today have a plastic welder and PVC rods. Cracks like you describe can be partially ground and then refilled. It does require a deft touch however, since there's a pretty fine line between melting PVC and burning it.

Thanks for all the great suggestions.

I decided to give the Plast-Aid a try. I'll report back after I receive it and do the repair.
