Question about Hayward SAND FILTER, PRO SERIES

1 Answer

We had a lot of rain and mud got in the pool. i vacuumed the pool twice and the third time i vacuumed it, i put the filter on "waste" instead of keeping it on "filter". it cleaned up very well that way but then i tried to backwash the filter after vacuuming and it would not backwash like it has previously. now when i turn the power on the pump, the jets are not circulating water and their is basically no pressure on the guage on the filter. the water level is low due to the fact that we let the water "waste" when we vacuumed. Can you help?

You may have to change the sand from to much mud. this requires removing the valve from the top and syphoning the sand with a "sand changer" then removing the latterals from the bottom.( they unscrew from the hub inside the filter and cleaning them. Return the correct the amount of sand covering the tube shaft that connects the valve to the hub sot he sand doesnot clog the flow again. Return valve to the top and it should flow freely again.

Algae dust in pool


I think Brandon's answer deserves a little more time and a slight explanation... as I think it is Spot On!
Algae dust is usually "Already DEAD" algae!
And normally it is way to Small & Fine to be trapped by the filter.
We here on this forum do not know what type of filter you have, But if you do have a "MultiPort" valve as Brandon suggested you turn to the "Waste" mode, you will not use the filter mode to vacuum, as this will only BLOW the Fine Silt like substance right back into your pool, spreading out into the water to be suspended turning your water cloudy if not green, until it settles, and once again you have a covering of Dead Algae Dust on the floor of your pool. But when the filter valve is in Waste mode, you will bypass the filter and the return line altogether and your vacuumed algae silt will be sucked up into the valve, and OUT the valve to waste. And just like that all of the algae dust is vacuumed out and did not Blow back into your pool.
I just had a situation where we cleaned up such a pool where the customer couldn't get the algae out, we came out and vacuumed to waste. And I by chance took a picture of the partially vacuumed pool and Dust remaining.

algae-dust-in-pool-iwrnrkacomuoeuyhvucmvd0t-2-0.jpg If you don't have a multipart valve, then if the pool has no debris but only dust, then and ONLY then, should you use Backwash mode. You NEVER want to vacuum a pool with debris in Backwash mode! NEVER!!! Because the larger debris you are vacuuming will get caught in the internals of your lateral drain assembly or your DE Grids. then it will be very difficult to un clog them, which in turn will reduce proper water filtration efficiency! But the algae dust will be able to pass right on thru. If you have neither of these types of filters because you have a Cartridge style filer, the elements may be able to trap the dust, if it is still to fine to filter, you obtain an additional pool pump, place it pool side, and in the pump out the pump will be two vacuum hoses and away you go.

Good Luck

While vacuming loses suction, sand filter pressure goes high


That increase is due to the filter loading up with debris. Is the pool unusually dirty? If there is a lot of dirt and silt in the pool use the "waste" setting on your backwash valve while vacuuming.
This allows the water to bypass the filter and go directly out the waste line. Keep an eye on your water level because you will be removing water from the pool and may have to add more.

I have 7 year old Hayward ProSeries, S-244S, H/R Sand filter. I've notice that when I vacuum the pool, dirty water returns to the pool. I've backwashed and the spider gasket is fine. No sa


sand filters only have limited filtration. If the dirt is very fine such as dead algae, it will go right through the filter. Use a clarifier to help give the filter finer filtration. Do not vacuum until you can see what you are doing, then vacuum on 'waste'

BACKWASH b> PUMP - BOTTOM - THROUGH FILTER - TOP - WASTE For reversing flow for cleaning filter. RINSE b> PUMP - TOP - THROUGH FILTER - BOTTOM - WASTE For initial start-up cleaning, plus resetting filter bed after backwashing. WASTE b> PUMP - WASTE For vacuuming directly to waste, lowering pool level/draining pool. CLOSED b> NO CIRCULATION PAST PUMP PORT For shutting off all flow to filter and pool.

I put my Hayward ST180T on rinse to vacuum the pool and I ended up with sand in the pool what happen?


You are using the wrong setting to vacuum. This type of pool filter should be set to "filter" for normal vacuuming or to "waste" for heavy loads. The "rinse" setting makes sure that all of the dirty water is out of your filter after backwashing.

Why does the material i vacum up come out the return??


If you are vacuuming a lot of debris or algae, you need to vacuum to waste. 1. You'll turn the equipment off, 2. You'll turn the valve to waste, 3. Turn the equipment back on, and 4. Vacuum the pool like you normally would. Only this time, the debris and dirty water goes out your backwash/waste line. You also don't have to backwash and rinse afterward because none of the debris went inside the filter.
Any time you vacuum up just a small amount of debris, you'll vacuum on filter and then backwash (30-60 seconds) and then rinse (about 30 seconds).

We have a hayward 244t sand filter. I was trying to learn how it works. I was trying to vacuum the pool but all the trash is coming back into the pool. What do I do?


For regular vacuuming, these pool filters should be set to the "filter" setting filter control valve. However, if you have a heavy load or the debris seems to be coming back into the water, you can try vacuuming with the filter set to the "waste" position. This will bypass the filter and vacuum directly out to waste.

Not filtering, back wash and waste won't work


Try consulting the owners manual for these pool filters. They have a whole section about the different settings on your multi-port valves. It also has a troubleshooting section.

NO SUCTION AFTER VACUUMING POOL


Did you use a trash plate? If not you have something stuck in the pipes and need to use an air compressor and blow from pump with main closed. Debris should shoot out!
