I have been using this with good results. It's non toxic as well.


As long as you make a good connecting it is never going to leak.

Since spray bars are made to leak, I just don't sand the ends enough to make them loose and stick them together without adhesive.
Silicone if you want to seal the joint but may want it loose later. PVC cement if you want it permanent.

Depends on how much pressure will be coming out of the spray bar. If the pump or canister has strong flow either increase to hole size to slow the flow or just make the bar permanently sealed with primer and glue. Silicone and plastic don't work very well. Especially when the inner pressure is different than the outer pressure. Equal pressure and silicone can be used to hold but it won't have great holding properties. Silicone will fail eventually under pressure when its used on something that it shouldn't be used for.

People use water for their tanks that flow through PVC lines in their homes that are sealed with PVC cement. Let the cement cure fully and it shouldn't be a problem. Read the recomendations on the can, most give two time limits the first for when the connection is usable, the second for a fully cured time. Go with the fully curred time and double it.

all purpose pvc glue is fine. especially the stuff now a days, its low voc, less of the nasty stuff, but also has a shorter shelf life once opened, its thicker.
i wouldnt glue anything that is inside the tank, any leak will be contained anyway, and youll find the need to make adjustments in the future.
just glue everything that can leak outside of the tank.
