Best fitting for overflow plumbing

[skijumpersc]

I'm upgrading to my first tank with a sump and i'm pretty unexperienced in the plumbing department.

What is my best option for this elbow that will allow for easy disassembly if I have to take the tank apart. The previous owner was just using friction, but I want something more secure than that, however I don't want to epoxy it together.

Im thinking gluing a male adapter to each end and then using a 90 degree threaded elbow is my best bet. Am I overlooking an easier option?

A PVC Union is the standard go to for situations such as this

These can be purchased online or at most box stores for relatively cheap with different fittings either slip or threaded on one or both sides.

Oh and while you're at it you might as well replace that ball valve with either a quality true union ball valve or a gate valve. Gate valve being my preferred option given its easiness to tune.

Using a friction fit on pvc is asking for alot of trouble when you are moving water from a sump to the tank or the other way.
As JoshH said, use a pvc union.

Only if you need a valve in that line too.
Regular unions are cheaper.

I think he was referring to my comment about upgrading the current valve itself . And yes @skijumpersc that is one of the valves I was referring to

Yeah. That comes from not reading every single post thoroughly.

One thing I do when I by valves from a box store.
I test every one of them on the shelf.
So are just easier to turn than others.

Youll want to figure out if you want to glue or thread (most prefer glue) to join your fittings. Using both is a pain in the butt.
And on that note, you should be using a pvc glue like red hot blue glue. No primer needed but is usually a good idea since not everything is always clean and residue free.

Well after trips to the home depot and the plumbing store I've determined that it's some janky Chinese **** and doesn't play nice with the fittings we have over here. Looks like epoxy is going to be the solution.

What fittings do you have that standard pvc fittings from lowes or HD wont fit into? I would not use epoxy for pvc. Pvc glue is the only sane solution for a dry floor around your tank with slip fittings.

Ironically it's probably not Chinese and is just Metric plumbing, for this you would need a plumbing adapter or replumb the bottom portion after using an adapter union..

yeah, you're right, I meant PVC glue, in my mind I was thinking of it as an epoxy since its two parts.

As for the fittings, im not sure, the walls are thin. the threading matches 1 1/4 fittings, but the OD is somewhere just shy of 1 1/4 so nothing would fit snug. I got the tank used so i'm not sure where these were found originally

What type of tank is it? Does it have a manufacturer name?

yeah, thats probably what it is. the bulkhead female size says 1 1/4 and 32 which would be about the equivalent in millimeters. regardless, I think I'd have to order something that would function. down the road I'll probably redo the bottom portion, but for now PVC cement it is

yeah, its a cadlights. Looking at the website it says its a "heavy duty grey uPVC material"
