We've had some bad storms here lately and my in ground hot tub sits directly under my gutters which got full and proceeded to pour granules in to the hot tub. It's on a separate pump and the granules are too heavy to swirl and go in the filter, I'm not even sure I want that to happen even if it would. SO, I've been brainstorming about using a wet/dry vac to suck it out. Does that sound like the dumbest idea ever? LOL!! The hot tub levels out with the pool and the pump I have for the hot tub doesn't have any drain function or anything...so I'd have to have a sump pump to drain it and I'm not interested in all that. Any one have any advice? It's really not that much, a quick hit with the vacuum should get them out.
