Browse Forums Building Standards; Getting It Right! 1 Jan 30, 2015 4:17 am Hi guys, Started a new build and builders are preparing the site for slab pour. We had a lot of wind this week and the foam blocks used for the slab got blown around, pushing down the site fence and etc. One of the damages caused was the foam blocks knocked over the vertical pvc plumbing stacks and cracked it at the base - the pipe was pretty bent over when I first saw over with a block over it. Before Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ It appears somebody has since come and "cleaned" up the site a bit, and straighnted up the pipe, but its still cracked - looks like there may have been a bit of glue applied to the pipe, should I be concerned about this still being visible cracked/damaged? After? Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Re: Damaged plumbing stacks prior to slab pour 2Jan 30, 2015 12:19 pm The fitting has 'sprung' as evidenced by the split you can see. The "glue" is solvent cement that melts then melds both surfaces to form a single part. As you can see in the photo that I have posted, the pipe had partly separated from the fitting and the fitting had also split. There is a 'greyish' colour showing on the pipe between the split and up to the upper level of where the fitting was. I take this as being the solvent. If so, then the solvent hasn't been effective. I cannot see any (red) primer. Primer not only cleans the two surfaces, it also removes the glaze, allowing the solvent to be more effective. The pipe gravity drains, there is no pressure but the fitting is damaged. Email the builder a copy of the photo and state that you are concerned about the damaged PVC fitting and ask that the builder attends to the matter before the slab pour. It is unacceptable as is. I would also be asking for the damaged fitting once it is removed and inspecting it for evidence of primer being used. With plumbing, if you find evidence of slackness, invariably there will be other instances/issues. Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ 3in1 Supadiverta.

Re: Damaged plumbing stacks prior to slab pour 5Feb 02, 2015 1:43 am Crazyk The pink stuff is the primer I think and the blue the solvent. Correct me if I'm wrong. You are correct but I can't see any pink/red plus the pipe and fitting shouldn't pull apart if the primer and solvent has been correctly applied. The primer has to be wiped on, the reason why the container doesn't have a brush and also the reason why many don't like using it. It is against the pipe manufacturer's fitting instructions to not use primer and they are very strong about this directive. You can get clear solvent, the blue solvent can be messy. 3in1 Supadiverta.

Re: Damaged plumbing stacks prior to slab pour 6Feb 02, 2015 9:44 am As SaveH2O says the pink primer should always be used. I've tried to separate a piece of pipe from a fitting in the past where both primer and glue were used and it is next to impossible without breaking one or the other or both.
