drain question

[Dave 777]

does anyone know how many gallons per hour a 2" drain will provide? Thanks

If my calculations are correct I have 2 -1" drains and I get approx 1200 gph
so your 2" drain should do around the same output.
I hope that helps.

actually it will do approximately 4x the flow of a 1"

My new setup is 400 gallons. It is drilled for four 1 1/2" drains. I wanted to take two of the 1 1/2" drains and combine them into 1 2" drain. So when all is said and done the four 1 1/2" drains will choke down to two 2" lines to my filter system. I used the drain calculator on another site (thanks dan) and so far everything I researched seems to be cool with doing that. I'm trying to stay on budget and not have to buy a bunch of 3" PVC and fittings for my drains. keep the input coming I'd appreciate it.

Oh and another reason is only having 2 returns going into the filter instead of 4.

2" drain will do approx 2500 gph at max load. What I am gonna run on my 120G

so two 2" drains will do 5000 gph. I think I will be cool then. thanks.
