Waiting period after gluing PVC pipe
Jon Davis
you can start running pond water through it? I need to redo the drain
from my biofilter back to the pond. I have 1-1/4" pipe on the biofilter
input and 2" PVC pipe on the output (drain); so, it is pretty low
pressure. I'm more worried about getting chemicals in the pond by not
letting the glue age long enough; although, I don't want to leave my
biofilter sitting idle too long.
Also, I have a couple of aquarium air pumps I'm not using. Would
setting those up to percolate up through the biofilter help keep the
bio-bugs alive for a longer period of time?

I've applied 80 psi to PVC within 5 minutes.
The joint does not have to "cure" or polymerize.
The "glue" is solvent, and as soon as it evaporates, it's done.
This is solvent welding.
Can accelerate evaporation by using a heat gun to warm to the
joint gently, not any warmer than you can hold comfortably.

If worried, discard the first few gallons of water that pass through
the new joint.

it you wouldn't need to wait for more than 15 minutes. If it were high
presssure longer. The glue if it falls in the water will just float in a
scum and you can pick it out. I wouldn't worry.

This is a bit OT but
I have had good luck using "no hub couplers". They are a rubber sleeve
with hose clamps at both ends. Makes disassembly easier for cleaning ,
changes to plumbing etc. They are simple to install, and fairly
reasonably priced. They will also allow for a little misalignment and
you don't need any glue (which will be dried out the next time you
really need it *G*) Good luck

I use "blue glue" and wait about ten minutes for pvc joints using pressure fittings (as opposed to dwv) on a
pressure line with about 40 psi. With regular clear glue, I wait about 30 minutes. If gluing pressure lines over 4", I
wait about twice as long.
For air lines and drains, I don't wait hardly at all.
If some glue gets in the water, just scoop it out with a net. Its the primer you need to keep out of the water. BTW,
in a pinch, you can kill wasps with the primer.

Good idea for when you turn the water off. Keep 'em oxygenated.

That's what I used to connect the plumbing system to the pump. That way I can
take out the pump easily if I need to do maintenance or anything. Most of the
system is pvc that is glued together. BTW I used black duct tape to wrap the
pvc. It camouflages it great. Can't even see it at the bottom of the pond.

Yeah, but I have such a hard time trying to get them to hold still while I
paint them with that little brush....

That's what we call a "Fernco". I use a bunch of them. Very useful, if not very pretty. Using one to connect a
pump works well for several reasons. One of the best is that if you close all the valves with the pump running, the
Fernco will usely blow off before something else breaks (like the pump or a glued fitting).
