Every time I turn the pump off (to backwash, rinse, waste etc.), the pump primes again. I have gone into settings and changed the sensitivity setting from factory 1 to 100 but it still primes when the power is turned back on. I have also changed the priming delay to 10 minutes and it still primes. I can disable the prime feature but don't want to. I do not have any leaks and the pump is full of water. The reason this is an issue, I inherited the pool and the hose to backwash/waste has a couple of leaks in it and I don't want to replace it yet and I have to add more hose to it and the union place has to be held in place when it primes or it comes apart and becomes a firehose! Any advice or help is greatly appreciated.
