gluing pvc

[MaxCanada]

when im gluing 90's and tee's unions ect. do i need to be worried about the excess glue on the inside of the pipe when i slip the fitting on? using the purple primer and the grey glue

I usually don't, rinse it out with water with your hose when it is done, and the excess usually just wahses out.

No it won't matter but don't run water thru it until it has cured! You can use a paper towel to wipe the excess away.

Not sure if this has been already considered, but I was advised to try to use 45's instead of 90s when possible.

The excess inside is not a big issue. Most people over glue their solvent welds. Less is more if you have good coverage. The cement buildup on the inside and outside can soften the pipe and allow for leaks later, but that's in a pressurized system running 50-90 PSI, which we don't run in our tanks. The process is prime the male, prime the female, apply a nice even coat of cement to the male, then the female (the primer MUST still be wet when you apply the cement) put the fittings together and make sure you give it at least a 45 degree twist as you seat them. The grey (probably 711 class cement) needs a 24 hour cure time. Others need less, but are not as strong a cement. Made tens of thousands of solvent welds when I was in the sprinkler business. Good luck!

use this stuff called red hot blue glue... i found it at home depot and this stuff is solid! never a leak ever..

ImageX, Christie's Red Hot Blue Glue will work. It also is a fast drying cement that doesn't require a primer for the pipe diameters we use. It should be very safe at our low pressures too. I did have a problem with it in full pressure irrigation lines coming undone. One big issue is that it drys so fast you really need to hurry when you stick the parts together or you'll not have any time to adjust the angles or get it seated all the way. Nice thing though is that you can put water on it very soon after you cement the parts.

I have used regular #31013 at HD for years ........... give it a twist, dry for 10 minutes and use, no issues ever. Our systems are very low pressure.
