Standard PVC sizes for returns and overflows

[cabenn]

Just wondering if there is some standard size to use for the plumbing?

Do you typically use 3/4" pvc for returns and 1" for the drains?

Do you typically take two overflows and merge them into 1 pipe and then to the sump?

I'm getting ready to plumb this stuff up before the drywall gets in and wanted to know how everyone typically does this?

The typical RR tank comes in those sizes. I would avoid joining the drains together. If one gets clogged, atleast the other would still drain.

Ok, thanks. I'll run 2 1" overflow pipes to the sump and then 1 3/4" return. The head pressure is only like 4' since they are on the same level so I won't lose too much pressure going up any floors.


I've typically only had 1 overflow so didn't know how everyone handled two overflows.

I assume on the return people typically drill the glass and have the bulk heads fit appropriately.
