My waterfall's 14 yr old dedicated pool pump died last year. When my pool guy replaced it, he installed a spring check valve without my direction (one did not exist prior). Before the check valve install, the water in reservoir at the top of my grotto/waterfall would recede and empty after turning off the pump. Since the check valve install, the reservoir remains full of water. This is causing me a bunch of additional labor because invariably the water turns disgusting and full of rotting leaves. And in the summer it acts as the perfect spot for mosquitos to breed. My pool guy said to drop a chlorine tablet in it in the winter, which I found to be peculiar for such a small body of water.
My question is this: Is this check valve necessary for a waterfall pump? We run it maybe 10-15 times a year.
Thx.
