I backwashed my filter on Monday. When I added the DE slurry, I noticed the DE blowing into the pool through the jets. Unfortunately I had added a few pounds before I noticed it happening. When I looked at the filter, the pipes were vibrating quite a bit. I turned off the filter, switched to bypass and the shaking stopped, so I'm assuming a grid or something else came loose inside the filter. I'm not yet comfortable getting inside the filter, especially given that something appears to be out of whack. The local pool repair guy said he'd get to me as soon as possible, hopefully this week, but he hasn't come yet. There's noticeable dusting of DE on the steps and benches. I have two questions:
First, does anyone know what might have happened that would cause the vibration/shaking?
Second, my granddaughters want to swim this weekend. Is it safe to swim with the DE in the pool?
