Advice on plumbing my drilled 135g

[JK47]

That should work out nicely.

Thing with drains is the closer to full capacity the quieter they are. Unless you hit it perfect the pump will either pump more than you require, a good thing using a tee to divert excess back to the sump, or it will be under sized, thats all she wrote and you run what you brung.

Using a valve to restrict flow on the drain is like imatating full capacity and you can use this technique to tweak for silence. Consider using a gate or ball valve in the horizontal run on your drains.

Alweays leave room for error and let the drain flow more than the supply to the DT. Balance the system then back off ie open the BValve some, for piece of mind.

Elting that is very good advice your getting, I agree. Your drawing is very detailed and understandable, thanks for that. The above is very solid advice and will you keep and your loved ones happy with the setup instead of hating it due to the sound alone, despite the flow.

lets see if I understand now:

OK so lets say my sen 900 return pump is rated for 820 gph @ 4'8" of head. My drains will be able to handle at least 1200 gph (2x 1" durso overflows)

So I want ball valves on the horizontal part of the drain lines, that way I can restrict the flow to "match" what the pump is returning. Correct?

Once it is balanced, open up the valves a little, so hypothetically they are draining at ~840 gph, that way I have a little breathing room.

Also, I read that you can drill a hole in the side of the end cap and the slip of the durso pipe, to adjust airflow in the drain:

Would adding this to my set up be beneficial, or would the ball valves do the same thing. Having a ~1" sight window in the 1 1/4" vinyl I should in theory be able to see if air is coming through, and by opening/closing that I could remove the air from the drain. Correct?

I dont quite understand the red part. So basically, on my drains. I want it to go from Bulkhead to a short section 1" PVC and then vinyl all the way to a 90 degree sweep into a short section of PVC that the filtersock is attached to? Also, I can't seem to find 1" 90 Sweeps, only 1 1/2".

As far as the return is concern, how far up off the pump do I want the Y or does it matter?

A sharp 90 will work fine; a sweep 90 will work even better. We could be splitting hairs here. I was just pointing out how to maximize the drain flow.

Placement of the Y is not very critical. I would try to go as long as possible with a single line then Y off to keep the shortest amount of pipe in the system. If you Y immediately from the pump then you’re using double the plumbing and double the drag or loss (head). Again, splitting hairs, just do what's easy for your back while you’re under the tank LOL

Cool I think I have a better handle on it than I did before. Anyone have any other tips. I am greatly thankful for all of your help. Happy turkey day
