Am I choosing a good combination? pump & filter size

Well Done Leena for getting your pump and filter sorted, sorry not been around but my IP address frequently gets blocked by the administrator so I can't view the forum.

Carl your post doesn't make sense to me. Why turn to waste or is it rinse? before backwashing?
Waste setting bypasses the filter inside the multiport so just flushes water away (ok when vacuuming gunk directly out to waste)
Rinse puts the water through the filter in the correct direction, but pushes the water to waste rather than back into the pool as it could carry dirt but is used to re settle the filter bed after backwashing and before setting the valve to filter once more.

Domestic filters backwash quite badly so often take several minutes to clear the dirt from the filter, best to use a white piece of card behind the sight glass on the valve to actually see how dirty the water is but it can take a minute or two to expand the filter bed to a point where it starts to release the dirt properly.

Leena just over halfway is all the sand you need as the space above is to allow the sand be to expand during backwash without washing filter sand away as well.

That's embarrassing! I've been doing it wrong for years! I think it's because you cannot SEE the multi-port valve labels where it's under the deck.

Now here's the thing: From my experience, of virtually ALWAYS having gem-like sparkling clear water that is very stable as long as I follow my own rules of regular testing and minor adjusting, it seems it doesn't matter as much as you'd guess whether you use "Rinse" or "Waste". I ALWAYS backwash until my sight-glass runs clear for at least 30 seconds. The sight glass always runs clear for 30 seconds on backwash before it goes cloudy, and you certainly don't need a white card to see it. But there's no sun glare on the glass to confuse me.

Thanks. I so did not know you are suppose to turn the power off when switching between rinse and backwash! Also I hif rinse resettles the sand bed then I should do it after backwash. I was doing it before. Ok going to do it now. I'm hoping this is the problem, maybe I just haven't properly cleaned that dead algae out.

Thank you Teapot, for phrasing your response so well. I couldn't figure out how to do it. I was a bit confused and was attributing Carl's post to exhaustion or... maybe the Guinness! Hahaha

Carl, I am still wondering what the answer is to this question:

Why turn to (anything) before backwashing?

You probably have some good reasoning and I'm curious!

ok, Im crazy because I WAS turning the power off when switching between rinse, backwash & filter. I was just doing it without thinkin I guess so didnt even realize it. THis time I went to backwash first, ran for about 80sec on high. You were right the water got dirty after 30sec, then sand come out for 30 sec, then it went back to clear. Then I did rinse for 30 or 40 sec, then back to filter. I left the filter on low, gonna check it after 6 hrs and see if thats the end of the "clogging" problem. Its showing around 5lbs of pressure, but I never remembered to look at the pressure when it would act clogged, so no idea if it was rising or not.
I was not rinsing after backwashing, nor backwashing long enough, so hopefully that was the problem: I had never cleaned all that dead algae out and wasnt resettling the sand properly. We wil see..... hopefully thats all it was......So ready to be done with filtering/pump problems after 2 yrs of misery!
Next I need to find that leak, we keep wastin so much water because now that the rains have stopped, we have to keep adding water every few days to keep it above the skimmer and return. SO many times I forget the water hose is on or it flips out of pool and runs on ground for a while before I remember I left it on! Yikes, I hate waste! When I start concentrating on the leak, should I start another thread?

Does the manufacturer calling for it help?

Works for me.... !!

It seems really strange, though. I can't figure out any benefit.
