Our customer Charlie called us because his spa was draining back into the pool every time the pool pump shut off.
Solutions provided:
Our technician went to investigate his problem. He replaced the Jandy valve diverter and caps, it helped some bud didn't solve the problem. We had to go back out to his house at a later date and our tech. replaced the check valve internals on the spa waterfall plumbing at the equipment and that stopped his spa from draining into the pool.
