So my new pool has been opened for about a month now, and everything has gone swimmingly (I am officially a dad now, so I can get away with that joke) following the TFP recommendations from the start. When my pool builder rep was out for pool orientation, he said that I would need to disassemble and clean the filter at the 3 month mark due to the new plaster. He also quickly informed me that he would come back out for $90 to do it for me. After reading the thread on how to clean a DE filter, I feel confident that I can perform this task myself. My question is, do I need to clean the filter at 3 months regardless of my filter performance? So far after a month, my filter pressure has risen pretty much zero. He told me I need to backwash every month regardless of pressure, so I was planning on doing that this coming weekend. I just wasn't sure if they were trying to get another $90 out of me, or if I truly need to thoroughly clean the filter at the 3 month mark?
Thanks.
Thanks.
