potentially really dumb plumbing question...?

[thebigblue]

on my 125 gal drilled RR tank i have 1" BHs for drains and 3/4" returns in both overflows...

i wanna replace my flex tubing with flex (or hard) PVC...

regarding the drain BH thats in the overflow, how should i plumb the drain line so i can take the overflow BHs out in the future if needed...i guess i could throw a union right after the BH but then how do i get the BH out of the overflow when/if i break the tank down?...

cut it out somehow?...

does this make any sense?...

also, how long do i have to wait for PVC primer and cement to dry before letting water run thru it, the tanks all ready setup!...

thanks

Since the fitting is slip where you attach the downpipe to the bulkhead- I think the only way is to cut it. Leave the pipe a bit long and you can use the BH again. If you mean just to detach the tank from the hose, ball valve and a pressure union will let you detach it.

Read the label on the cement- I think you can use it fairly soon but I would wait overnight.

well, i know i can get BHs that are slip on one end threaded on the other...or slip on both...or threaded on both...

i think my best bet might be to use the slip BHs and glue a decent length piece of PVC to it, then use a union fitting hooked to that...then on to the sump...

if i have to take it apart i will have to cut the pipe above the union, then pull the BH thru the overflow hole...

i think... :lol:

You are on the right track, Brad. Just plan to cut the PVC below the bulkhead and either re-glue with a slip fitting or replace the bulkhead. I just decided on the latter, and have a few extra bulkheads around for that purpose if necessary.

Give yourself 24 hours between gluing the PVC and running water through it.

PS there are no dumb plumbing questions, only dumb plumbing. Never be afraid to ask.

If you use a BH fitting with a threaded end on the bottom, then attach a union to a male threaded end you could take it apart as needed without cutting anything.
