Question about Hayward SAND FILTER, PRO SERIES

1 Answer

I have a P20 Pantera and Duo Clear 130. The Duo clear is reading no flow even after water passes 71 degrees and i've backwashed the filter several times. The return into the pool sends out dirty brown water with sand in it during the Waste setting, but is fine on all other settings. Do I need a new filter, to change the sand or replace a gasket? Help please.....thanks.

The last time I saw this there was a valve problem on the controller and the filter sand needed changed. If that sand has been in there more than 12 months and running most likely the sand needs replaced. While you have it open you can check the pipes and fittings in the Filter Unit to make sure something didn't come loose. If I remember correctly it recommends changing the sand every 2 to 3 years unless there is a lot of build up which you described indicating the need to change it. The 2 to 3 year recommendations comes not so much because of the sand but to inspect the inside of the filter unit as well.

I,ve just opened my pool and when I backwash the filter the water comes out at very high pressure. This is not normally the case certainly not for the last 10 year. Is there a problem with the filter,


No.
Nothing in filter will increase water pressure. Whatever water the pump sucks in will flow out of whatever port is open, in the case of backwash, a Waste port open. So... What the pumps takes in, you will see flow out when you backwash.
No problems that I can think of to look for.

Spa indicator says Water SW Open...what does that mean and how do I fix?


This means that the pressure switch is not closing. Generally, this is a lack of water flow issue. The main cause is a dirty filter. Clean cartridges, backwash sand, backwash and recharge DE, whatever is needed to clean the filter, this should fix the problem. If not check other sources of restricted flow: filter baskets, pump baskets, shut-off valves. If everything is clear and there is good flow returning to the pool it could be a bad pressure switch. Replace with the correct switch for your heater.

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'

How do i get a higher flow into my pool


The low flow could be caused by a clogged filter. If you have a sand filter and the pressure gauge is reading a high pressure then turn the control valve to Backwash the sand filter until the water is clear in the waste pipe (usually for 2 to 3 mins). then turn the control valve to Rinse for about 1 min then turn the control valve to Filter.

How to use backwash to waste


When the filter get clogged the pressure in the filter increases and there is less water flow returning to the pool.
If your filter is a sand filter, when you turn the valve to backwash and turn on the pump it reverses the water flow in the sand filter to flush the dirt out of the filter to waste. Look at the window openning in the waste pipe and keep the backwashing goinging until you see clear water.
Then turn off the pump and move the control valve to Rinse, turn on the pump for a few minutes, this returns the water flow back to normal but the water goes to waste to make sure the sand filter is clean.
Turn off the pump and move the control valve to filter and turn on the pump. This mode is the normal operating mode and the pressure gauge in the sand filter will show a drop in pressure.
Some pressure gauge shows a red section to indicate when backwashing should be carried out.

I need to know what all the settings are like bacwash filter on the valve system


FILTER is the valve position when the system is in the normal filtering mode.
When you backwash the filter you first need to turn off the pump, place in BACKWASH position, and run the motor for 45 seconds (or until the backwash water is clear). Turn off pump and run in the FILTER position for 15 seconds. Repeat twice more.
The RINSE position is to clear any dirt in initial start-up cleaning, plus resetting filter bed after backwashing.
The WASTE
position is for vacuuming directly to waste, lowering pool level, or draining the pool.
The CLOSED position is for shutting off all flow through the valve.
The RECIRCULATE position allows water to flow from the pump through the valve and directly to the pool.

You will probably only to use the FILTER, BACKWASH and maybe the RINSE valve position. The RINSE position is not as important as indicated by the fact that many backwash valves don't have a RINSE position.

I hope this helps.

I have a Hayward S310T filter. It's been running 24/7 for over a month. The water does not appear to be clear, even after floccing. How do I tell if the water is being filtered or if the filter is...


Backwash the filter. If the water coming out of the backwash line is not dirty you need a sand change. If the water is dirty you need to continue let the water filter and back washing once a week. Also make sure the six way is on filter and not recirculate

After I vacuum the pool, backwash it and then turn the filter system back on it blows in a lot of green water back into the pool. What should I do?


1st Green water is algee. Kill the algee in the pool. 2nd when you're finished backwashing the filter. Stop pump and move valve handle to rinse position. Then restart pump. Run in rinse mode until glass is clear. Then stop pump again, and move lever to filter position. When you're backwashing, you're reversing the flow of the water through the filter. When you switch directly back to filter, anything left loose in the filter flows back to the pool. When you select rinse, it reverses the flow back to normal, but keeps the water going to the waste outlet until clear, that way that green puff of water will go out the drain.
