Questions about gluing PVC

[d3rryc]

I've got lots of practice gluing up Sched 40 stuff, but I have two questions:

1) Are there any issues/concerns/risks involved when gluing Sched 40 parts to Sched 80 parts, and when gluing SpaFlex to either?
2) What's the difference between "standard" PVC cement and the "rain-or-shine" version?

Thanks!

rain or shine works when wet. You wont have any problems glueing it all together, just purple prep it and glue away.

i always wondered about the chemical concerns with freshly glued pcv components. any input on that? how would you cycle it to clean it out?
do you just use alot of carbon?
sorry for the hijack but i thought it would be ok....

1. Schedule 80 is a stronger pipe so nope you ought to be fine.
2. Like said above the glue will work in damp conditions. I wouldn't do it in what I would call wet conditions though, as water weakens the bond if the glue can't actually touch the pipe. Although we use pretty small pumps and I haven't seen it blow apart but it is taught in irrigators classes. Also you run into the problem of priming the wet pipe.

To answer the other question asked the glue shouldn't really be in the pipe as you should always prime both sides then put the glue on the male portion of the fitting. This pushes the excess glue out instead of going into the pipe. Also it cures fairly quick so that helps and the glue actually repells the water. I learned this the other day when we had some excess fall into a puddle of water, it would move on top of the water. It's kind of cool to watch if you ever get bored. LOL
