Hello everyone.

I have a weird problem. Both this year and last year I had to replace the entire lateral assembly in my sand filter because the center pipe broke. Last year, I thought it was because it was just old--the filter is about 10 years old. This year, it happened again. Both times it happened about 3-4 weeks after we opened the pool and started running the filter.

I asked the guy at the pool store where I bought the assembly if he knew of any reason why this kept happening, and he said that the only reason he had ever heard of for this was that the filter froze over the winter. I don't see how that could be the issue--we drain the filter every year. Also, if that was the problem, wouldn't it have been broken and sand going into the pool from the time that we first start running the filter for the year?

Thanks in advance for your help!
