Hey guys! First post, but I've been lurking and learning here for over a year.
I recently bought a Pentair Superflo VST to replace my single speed Superflo. I went with this because the pump inlet is the same height as my old pump in an effort to avoid any more plumbing work (I installed an SWG earlier this year thanks to the confidence this forum gave me...). Jokes on me because 3 hours after installing the new pump the union nut on the inlet shattered. I bought several split nuts to try to simply replace it, but none of them fit and had to face fact that Pentair used a proprietary sized union.
Now I need to fix this but looking at the description of the diverter valves from Jandy make me wonder if my plumbing was bad to begin with.
How would you rebuild this? The left pipe is from the skimmer, and the right is from the main drain at the bottom of the deep end. The 3 way valve combines the 2 inlet pipes on the left and right and the middle feeds the pump. My biggest concern is space and how little margin of error I have for the two pipes coming from the concrete.
Is it acceptable to use the diverter valve as a converging valve in this instance?
The distance between the pipes is 15"; between the ends of the elbows is 11". 1.5" SCH 40 PVC.
I am planning on putting a union between the pump and this intersection and moving the pump back about 4-5" to meet the specification of 7-8" (5x where x=1.5 or the PVC pipe diameter) in the pump manual. Can the 7.5" include the union?
Should I also put unions on the pipes coming from the concrete before the elbows? I love the idea of unions but can't help but wonder why installers never seem to use them. I assume it is the price as they are about $15 each at my local Lowe's.
Cost isn't a huge issue. I'm more concerned with doing it right, and making it so that it is never this painful in the future.
Also please excuse the leaves, I'll clean them all up once I get the pump running again.
