Need a quick answer please on plumbing drain

[dfm34]

I am working on the plumbing for a 180 dual overflow and want to know if I can take the 2 1" drains and tee them together so they'd combine into one 1.5" drain into the sump?

Thanks in advance
Dan

Yes, I would also add a valve, ball or gate valve to adjust the water volume so it won't make so much noise. You may not even need it but it may come in handy later on

Thanks I assume you add the valve on the 1" side

Actually if you are combining into a single drain i would put on the 1 1/2" line otherwise could be a pain to balance both

i think he means put a valve on the return line. never put a valve on a drain line unless you're creating a siphon. and teeing drain lines together sounds like a recipe for a very loud drain. 2 1" drains for a 180 gallon tank also seems quite small.

Ok so I will put the valve on the return side. The drains are 1"" on the dry side of the tank on a standard pre drilled rr tank. How load will that be? I guess that is kind of a stupid question

Ok decided against this thank you all for the responses
