my builtin overflow is a square measuriung only 5 x 5".. The drain hole/Bulkhead is a whopping 2.5".. which fits a 1.5" pipe. I was thinking of going durso standpipe but then realized 1.5" piping and T and all that might not fit in this section. can i go 1.5" to 1" reducer and create a 1" standpipe
instead of 1.5" .. does reducing the pipe size have any ill effect and do I even need a durso standpipe?
Thanks
