Hi all,
I noticed a couple small leaks in the seams of my pipes going from the pump to the filter. It's a 2" line there, and 1.5" everywhere else, and it all looks a little weathered, like the sun gave it a nice UV treatment. I'm betting it's a few years old.
My question is about PVC pipes. What better, Sched 40, or Sched 80, black PVC (maybe not so good in the sun) or CPVC, and is there an issue mating these with the plumbing coming out of the ground? It seams most people use Schedule 40, nut most don't have a merciless AZ sun in the summer. I'm also going to put in unions and change the sand in my filter while I'm at it. Seeing how the prior owner didn't plan ahead and put them in, I'm betting the sand is as old as the pipes that are above the ground.
Another concern is the 3 gate valves I have for the return lines, and where they meet with the plumbing in the ground. It looks like it's been cut close to the ground in the past and the couplings are a couple inches from the valves. Should I unearth a few inches and re-do these?
One last thing, does it make a huge difference if I have long sweep elbows, or are the common 90 degree elbows are fine.
If I understand assembly correctly, I should use Teflon tape at the threads in the pump and filter, then assemble the pipes, then join the unions (Not teamsters )
Thoughts?
