    Backwashing DE Filter for First Time

    Hi, as I mentioned in my intro post, I just bought a house with a SWG pool and I've been using the BBB method w/ TF100 test kit from the start for a perfectly balanced and, thus far, easy pool owning experience.

    That being said, my filter pressure gauge has slowly been increasing ever since I bought the house and is now approaching the 25% mark. The pool levels are all fine - I'm sure it's just from all the leaves and debris that I get from having 3 trees hanging over the pool.

    I bought some DE (HE brand "Filter Aid") because I know backwashing will require replacing 80% of the DE, but I was wondering if someone could walk me through the backwashing process. I've never owned a pool before this, so if you could break it down to baby steps, that would be really helpful!

    Thanks

    This may help some. I was worried the first time I cleaned my DE filter when I had one, but once I was done I was like that was easy. Here is a video I found on youtube. You may want to google your brand and see if there is a video.

    Tip: unroll the backwash hose carefully and make sure there are absolutely no twists or kinks in it. It will balloon up and pop so fast you won;t believe it - and probably at the worst possible location.

    Hm, I don't know that I've seen a backwash hose...

    Is the waste port plumbed to a drain? If so you are all set.

    I guess it is, because I did the backwash yesterday and didn't see any water coming out anywhere.
