When asking a question on an unrelated subject another member noticed that I used DWV long sweep elbows on a couple return lines.
I'm going to replace tomorrow with sched 40 fittings. However, I may reconfigure my piping/equipment again next season.
I was thinking that instead of cutting and cementing a PVC coupling, short length of pipe and sch 40 elbow, I would cut and attach a female, threaded fitting to the return line coming from under the deck. The rest of the line would be configured with a male, threaded fitting at its end. This will allow me to reconfigure next year without shortening the pipe coming from under the deck.
Additionally, I'm planning on "vaulting" these pipes. I'll lay block on each side of the pipe (3 pipes run alongside each other) and then place flat stone on top of the block. The "vaulted" area will then be covered with gravel....it's only about 8' long and 18" wide. This will allow me to easily access for maintenance etc.
Thoughts on code, design improvement, alternatives or experience welcome.
