"U" shaped pvc fitting?

[JamesThomas]

Just got my modular marine 1600 overflow. Im looking for a "U" shaped pvc fitting. I like the look of it verses the 2 90s. I cant seem to find them.
also any tips on plumbing the overflow box would be very appreciated. this is my first build! my buddy built a custom sump 38 gallon and custom ATO. Tank is next on the agenda. looking at 180gal. having trouble posting pics from my phone too.....

Custom Aquariums sells 180s for their overflow boxes. I'm not sure the exact size, but should be able to find out fairly easily from them:

What size is the drain plumbing on the 1600? I use 1 1/2" U bends from HD on my MM 3600.

Looks like the exactly what I was after. I just measured and my bulkheads are 1 1/4. Im going to email Custom.

 

[JamesThomas]

l think the 1 1/2 would be a correct fit.

So mid measurement I found out I don’t know how to measure pvc fittings. It’s the iD. Mine is actually 1.00” pvc

From my experience pvc is measured by inside diameter. So 1" pvc has a 1" hole but typically an outside diameter of about 1.25".

It looks like the link only has sizes down to 1.5" I have a Marine Modular 1600. the 1" pvc slides into the three drains, so I would need a 1" u bend??

However, it essentially looks like a standard 1” elbow with a 1” street elbow.

that works. does the 1" drains seem like they are small for 150 gal tank?

Just an option,
But I have heated and bent pvc piping to make all sorts of off set and custom bends. 1” takes more time and if you over heat it can make the pipe brittle but it really isn’t that difficult.

This is 3/4” pipe I did for a reactor fitting. Took less than half an hour. I have done u bends no problem.
