2" Sweep 90's (Ells) Street Elbows

[MyAZPool]

I will be renovating the pool equipment pad soon (once the Arizona heat subsides ) in order to upgrade some equipment and fix some issues. I have read that sweep 90's (ells)/Street Elbows will reduce some of the feet of head.
Anyone have any suggestions/recommendations on some online retailers with reasonable prices?
Thanks very much for your input!

Not worth the added expense and effort to locate and order. IMO.

Make sure they are schedule 40 if you do decide to use them.

 

[MyAZPool]

Maybe so, but I'm thinking anything I can do short of building a new pool to decrease feet of head is a plus. Absolutely schedule 40. Thanks...

Why do you think you need to lower the head loss?

most sweep elbows are DWV(Drain Waste Vent) and not designed for pressure, so you already know you need schedule 40
if you do decide to use them don't use street elbows, the smaller diameter to fit inside the pipe will increase your head from a regular sweep elbow

Street elbows do not reduce to go inside the pipe. They're a coupler size on one side and a pipe size on the other to go into another coupler fitting.

your right, I was thinking something else
regular 90 degree street elbows will reduce flow compared to regular 90 degree elbows

I don't think that last statement is correct either.

I don't think that last statement is correct either.

on 2" 90 degree elbow is 5.5 feet friction loss
on 2" 90 degree street elbow is 8.6 feet friction loss

Oh, I thought you were comparing a sweep street with a non-sweep standard. Carry on

Correct. The regular elbow has lower head loss (greater flow) than the street elbow. But your previous statement was reversed.

regular 90 degree street elbows will reduce flow compared to regular 90 degree elbows

I am being told that there is no friction loss difference between the Lasco specialty Pool/Spa Slip-to-Slip sweep 90 and their Pool/Spa Slip-to-Spigot sweep 90 fittings, since the spigot end is the same ID as would a pipe id be, glued inside the bell end .
