Plumbing My Manifold Help

[ep3n3wp]

Looking to get some input on which way to plumb my return and build a manifold...

I mocked it up 2 different ways and wanted to know which was better.

Here's the first one..
Comes up into a wye... Then out the side into 2 Tees then continues on up to tank(basically manifold and return on same line)

Also coming out the top of the wye where the cap is I'm going to stub out for future(or water change valve)

No here is the second way
Up into a wye then out the side of the wye straight into the returns.. Then out of the top of the wye would come the manifold 2 tees.. Basically return and manifold in separate lines

then I'll stub out again for future(or water change valve)


Let me know what the pros and con's are and which way I should go..

Thanks

Tomato, tomato.

First way I think is better based on my limited plumbing experience.

Remove the y tho no point to that just use a 45 unless you plan to use it for something else where the cap is?

+1 Agreed, the 'Y' will cause back-pressure and may cause the pump to chatter if left capped.

OK... So ditch the wye?

I'd go with the second option.. I would Put ball valves on each side. One to control flow from your return. The other side in case u want to ever rebuild
your manifold.. Unions are awesome, come in super handy when you are servicing your equipment. So your not having to cut and rebuild, especially if your fittings are glued to closely.

Hmm... Debating on using the wye... Grrr...

Its all mocked up... To glue or not to glue....

If this is the option your going with. I would remove the linear pipe and elbow. Instead pipe it directly up to a 45 to bulkhead. Along the way you can add a valve and check valve. On the check valve make sure the mouth is facing down since the pipe is not completly vertical. I semt you my contact if you need help. I'm not home ATM, but I'll crayon you what I mean

Can you post a picture of the whole sump in the stand

Reverse your DT feed and reactor feed at the wye and then both will be on back wall for bracing/clamp install. Raise DT feed closer to bottom of stand giving reactor manifold room.

Well here's what I ended up doing/going with

Its still correctable if you glued it… .

 

[ep3n3wp]

What should I correct? And why?

You are doing a nice job its hard when others are giving option's Without a check valve everything will back siphon as shown?

I have a check valve also... Its behind the tank... I did this for 1 reason... In my old set up my fuge light was overflowing and blasting my check valve with light that ended up caking the whole check valve with algea and coraline.. So this time I put it where no light can get to it... and its a union check valve so I can remove it

Do you even need the check valve?

I've never used a check valve but how does it work when it's preventing water in the pipe and then you disconnect it?
