Hi there people, I received my 90gal tank(built in overflow) today and I have a few questions. what plumbing parts will I need for my overflow box? I know I will need bulk heads, Pcv glue? Primer? What other parts will I need? Can I buy these parts from Home Depot? Thanks in advance, photos of needed parts would be nice, Im a noobie

don't forget about unions and ball valves. they are always good to have if you ever need to shut the system down to redo some plumbing.

and yes everything should be able to find at home depot.

are you talking the plumbing inside the overflow? or from the tank down to the sump?

Your bulkhead holes should be 2 different sizes, larger hole for larger bulkhead will be the drain. The smaller hole, for the smaller bulkhead is for the return.

you will need some type of durso standpipe on the drain side of your overflow to reduce a waterfall effect and toilet flushing noise.

here is the link for all the plumbing parts you need to make your durso stand pipe

There are a lot of people asking plumbing questions today. I have used this same answer three times already

Any place you want to be able to disconnect the plumbing you will need to have a union.

If all your joints are glued (cemented) then there is no way to spin them on or off for connections. So where the pipes connect to the pumps or to the bulkheads or to your skimmer. You will want to be able to disconnect these items and they will require something that can unscrew. Along those lines any place you want to be able to slow down or stop water flow needs a valve (gate or ball). Here is the tricky part, some ball valves are also unions! This is great in an area where you want both. Here is a ball valve that is also a union:

Here is a standard ball valve:

and a gate valve (preferred as they do not get "stuck" but they cost a bit more...$20ish)

Typically you want valves on the input and output of your pumps so you can shut all the water off, unscrew and replace the pump if it breaks or needs to be cleaned.
