DYI Standpipe

Ah IC. A durso is the easiest type to make and typically pretty quiet.




Pretty simple to make but the key is to reduce the pipe size after the standpipe. So If you have a 1.5" Bulkhead in place already you should make a 1.5" Standpipe. Typically you would then drop the pipe size to 1.25" below the bulkhead to the sump however since it's only a 35 gallon and your flow rate is going to be fairly low you should drop it to 1".
If a 1.5" Standpipe won't fit in your overflow a couple bushings in the bulkhead will allot for a smaller standpipe. You could go as small as 1" for the standpipe and 3/4" for the drain line below.

If the durso design is just too big for the overflow no matter what look into a stockman or HGB.

Also just note that you need a 1/8" hole drilled in the top of the cap on the durso standpipe.

hmm good to know, think I will head out to the hardware store or red coral and see what I need for fittngs etc.

Try and fit a 90 that will male socket on one end, this will help with clearance.

went out got 1.5" fittings no way in hell the 1.5" or even a 1" fitting will fit in this overflow which sucks..so now i dunno what to do, i guess look into the stockman and HGB style, anyone have some good info on those?

What about a herbie overflow? Just have a straight pipe sticking up and drill a hole for a other bulkhead into the back of the tank that goes into the overflow? The straint pipe takes all your water (gate valve to adjust with precision) and you put a 90 on the new bulkhead and that's your emergency. The 90 can be high up and straight pipe can end halfway between bottom and the 90. I did this check my build thread. I drilled into the side of an external overflow but same idea.
