Finally picked up this bad boy
Pool non return/check valve. Should prevent water from flowing back into the pool. My main problem is that the motor for the pool is around 1m above the pool itself. So water flows back down and leaves an air gap. Probably shouldn’t be happening since it’s a closed system, but recommendation from Gus pools (great gent - even though I was out of his area of Fourways and Lonehill he was patient and gave me a lot of good advice)
He suggested a check valve to prevent the water flowing back. My issue was that it would take 10-20 mins before the water would start flowing. The cost of moving the pump is eye watering, but I’ve had 3 1.1kw pumps in as many years and the issue has been running dry over time leads to the pump overheating.
My main concern is that the recommended installation point is as close to the motor as possible, and I have the perfect spot for that but I also would have thought ideal would be at the lowest point where the water would ordinarily not flow back so the same level as the pool.
Anyone dealt with this before and any tips, is my thinking wrong and I should just trust the norm?
