Return pump plumbing

[Reefrookie733]

Trying to build the plumbing from the sump into return pump up to tank. My super dart gold has a 2" inlet into pump and a 1.5" outlet returning to tank.


SO the plumbing coming out of sump and into the return pump needs to be: ??

2" bulkhead at newly drilled hole ---> to 2" PVC pipe --> to 2" true union ball valve --> to 2" PVC pipe --> into 2" male adapter slip x thread --> into reeflo pump ??


AND the outlet would be: ??

1.5" male adapter thread x slip --> to 1.5" PVC pipe --> to 1.5" true union ball valve --> to 1.5" PVC pipe --> to 1.5" check valve --> to 1.5" PVC pipe ??

Essentially i am rebuilding what was given to me with the pump and cut off....see pic below, of course i am really confused on how i get the 1.5" outlet PVC pipe to merry up with the 3/4"
overflow return that the tank is currently plumbed for...lol

If you actually read all of this i probably owe you a beer! If you answer it all i will buy you 2 beers!!! lol

Thanks for your help guys. Sorry about the newbie stuff but i tried to be a really good medic in the army but have NEVER done any plumbing work!

Well I read it all lol. I am learning my plumbing in my project as I go. But from what you wrote it sounds right. I like the idea of throwing in a check valve. my last plumbing job I didn’t put one in because there is no way to flood my sump.

I think you may be overthinking this set up.
You simply need a 2in bulkhead, pipe, a 2in true union, and a 2in threaded insert.
On the other end all you need is 1.5in threaded insert, 1.5in true union, and pipe.

What about a check valve, what about water if pump fails or power goes out?

This should only be needed as a convenience.

Unless your sump is undersized it should be able to handle any back flow of water.

What size tank is it? You say your return piping in 3/4". You will need to further reduce the 1.5" from the pump to a 3/4" diameter return.
You can save some money by reducing the piping straight from the 1.5" pump outlet as smaller diameter fittings and piping is cheap... or you can use 1.5" fitting and piping up to the pre-installed 3"4" return. This would be my preference if it was my tank as I would "feel" that the longer length of piping and fittings of 3/4" diameter PVC would be restrictive. I dont know if it is factual or not.

Edit... to reduce from 1.5" to 3/4" you would use bushing and reducers.

Edit again... check out BRS "plumbing - sch 80 fittings...

Your gut feel about running 1.5" as far as you can then reducing to 3/4" at the end is factual. For max flow you keep the largest diameter pipe as far as you can. Neptune COR pumps come with a 1.25" output and recommend dragging that diameter as long as you can before reducing.

Thanks Jaeb! It's a 200G bowfront dt with a 75G sump

Thanks albert! I think i can reduce it right at the top of the tank since i am using the 2 overflow holes as a herbie overflow??

Monti, my sump is a 75G so i think it would handle it fine, but i cannot afford another divorce so im going with as much security as possible. $9.50 now or $9500 later! lol
