I have learned a lot visiting TFP over the last year (thanks for all the help!). We have no more pool guy. I've been testing the water myself and the Pool Cleaner I bought is keeping everything very tidy. Now that summer is here (in Los Angeles) I noticed that the return water pressure is a little weak. The D.E. filter pressure is up a fair amount, about 30 PSI from about 15 or so.
I read the sticky on cleaning a D.E. filter and had a couple of questions:
1. Is this something I should do myself, or get someone to do it? I am a bit maxxed out on my appetite for pool maintenance. On the other hand, in my experience the local pool guys don't really do a fantastic job, so it might be one of those "if you want the job to be done right,..." situations. I believe a simple backwash may be sufficient. However, I don't know the exact filter model. It is a Pentair 4000 series but the sticker on the side where you are supposed to check the box indicating size of the filter is blank. That makes it difficult to know how much D.E. to add after backwashing.
2. What size hose do I need on my Pentair 4000 series filter? The pool equipment is in a shed so I don't want the water/D.E. to spew everywhere. The drain pipe has a 2-1/2" outer dimension. Is it OK for the water/D.E to water my citrus trees or lawn? We do have a salt water pool, so I am not sure if that is a good idea.
3. Lastly, and unrelated, what in the world is a pool diverter for? I have one, but have no idea what to do with it.
Thanks in advance for any help/encouragement!
