Bulkhead Fittings for 1.75 drain and 1.5" return

kuroiknight · 08/09/2011, 10:57 AM

Hello Everyone.

Currently frustrated.

I have been doing a lot of research about Durso standpipes and I really want to build one. So far I am stuck at bulkhead fittings!!!!!

I have been to several places, from swimming pool equipment suppliers, Lowes, Ace Hardware, as well as several pet stores. No one has them in stock.

Equipment

120 Gallon All Glass Aquarium (bought it used, did not have the plumbing kit. The aquarium is 48 x 24 x 24)
30 Gallon tank (will be used as a sump)
Gen-X PCX-40 Mak4 Aquarium Pump 1190 GPH (external return pump.

The 120 gallon aquarium has 2 drains where the actual diameter of the hole is 1.75 inches, and 2 returns where the hole is 1.5 inches.

What size bulkhead fittings do I need to use? Once again I would like to run a durso standpipe that is about 24 inches tall (comes to the top of the aquarium just like in the write up for DIY Durso standpipes.)

What size standpipe should I use?

I know you can't get frustrated in this hobby or you will mess things up bad, but I am frustrated that no one carries these fittings. Any help would be appreciated!!!

A 1" bulkhead from BRS requires a 1.65" hole... that would work fine in your 1.75" hole

The .75" bulkheads require a 1.33 again, probably totally safe with your 1.5" hole

Thanks. After alot of wasted time I found a pet store that had exactly 4 in stock so I bought them. Ended up being a 1" and a .75". Last night I built 2 durso's for the drain. I just need to design my plumbing underneath and the return.
