deep heat returns and main drains,are they pre-plumbed correctly?
My pool builder is just about ready to gunite. My concern is that, after pre-plumbing the pool, the pvc pipe for the deep heat returns and the main drains are lying on top of the 3/4 inch stone base. These pvc lines run the entire length of the middle of the pool floor below the rebar. Just about all pool pictures I've seen show the pvc pipes below the floor rebar buried in the soil or stone with only the pvc stub-ups showing (coming straight up out of the dirt or stone).
The two pvc lines, ie, main drain line and deep heat return line, run side by side. They are 2 inch pipes so they will displace the gunite by about 2.5 x 5 inches (outer diameter). I am concerned that this will weaken my gunite floor. Is this an acceptable way to lay the drains and deep heat returns? Is it better (best practice) to bury them? I need to know before my pb gunites everything within the next 1 to 3 days. Thank you for your help.
