Durso Standpipe question

[Dr Joe]

The drainage fittings on the left would be better. Not only is it going to flow smoother (therefore quieter), using the street fitting removes a chunk of pipe and a glue joint. The DWV fittings also have a shallower socket and assemble easier.

Hate to add to the off-topic discussion, but "aluminum" potable water piping? I've been plumbing for ten years out here in Oregon and I've never seen that. I have seen blue PEX tubing that use almuinum brackets to make 90 degree bends...

NONO... The inside is coated in plastic too... its the best for UGJ's its flexable and stays where you put it.

I just finished making mine and I used the left 90 deg style and I can't hear anything at all. i would go with the one on the left because its less noise. On the end cap I drilled a 1/16 hole in each cap and it was perfect. Just my 0.02.
