Thank you for posting your question here on Fixya.com.

You need to check and probably replace the gasket inside the valve to stop the leak. The gasket kit is pretty cheap and not to hard to replace. We can try to get you the part number if you can post the valve brand and model. You should be able to call any local pool store with the brand of filter and get the part you need without any trouble.

Be sure in the future that no one adjusts the valve setting without turning the pump off. Moving the handle with the pump on can dislodge the gasket and then releasing the handle damages the gasket.

I have a Hayward s166t sand filter and no matter what setting I have it on tons of water is coming out of my waste line! This is my 1st pool and 1st sand filter!!


I used to work in a municipal swimming pool. 325,000 gallons!

It sounds like you have the sand filter on to clean if water is coming out of the waste line. That is called 'back flow'.

Basically, the water from the pool comes into the top of the filter and the muck settles on the top. You need to add Gypsum (Aluminium Sulphate) to the water which is a floculant. This makes organic material form into a layer on top of the sand. The flocculated layer further adds as a filter. You need to regulate the flow of water into the filter as too fast and you force sand into the pool.

When you clean the sand filter, you do a back flow. So by altering valves, you put the water from the pump into the bottom of the filter and the water lifts the muck and dirt off the top of the sand and discharges it to waste. It is important to also regulate the flow as too much will discharge the sand. That happened in our municipal pool and discharged 6 tons of sand in the space of 2 years.

your owners guide is here. Take a look at the pipes, valves and pump and work out where the flow is going to.

Hayward sand filter


Reference your pressure gauge as the 12:00 position. Going clockwise-
12:00 is Filter, normal running position
2:00 is Waste, water goes from pool and exits the waste line, bypassing filter.
4:00 is Closed, used only when servicing equipment
6:00 is Backwash, reverses water through the filter and goes out the waste line.
8:00 is Recirculate, water bypasses filter and returns to pool.
10:00 is Rinse, water goes through filter and exits to waste line, used briefly after backwashing to clear sediment from filter.
Note that the "pointer," not the handle that you grab, indicates which setting you are on.

If I turn to back wash, will I lose sand. Should I use waste out to clean the filter


Backwash is meant to clean the sand and remove dirt from the filter.
Waste simply pumps the pool water to the drain line and doesn't clean the sand.
If the filter has its distributors, the sand should be held in the canister.

I was curious about the height of sand needed for the filter to work properly for my Hayward pro series 180T sand filter. It is one of the old gray colored models, and would you mind giving me an...


A Hayward S180T sand filter holds 150# of sand. In other words, fill the filter 3/4 full of sand (to the point where the tank starts to round off). Make sure, however, that you fill the tank 1/2 full of water first. This will help to cushion the laterals and prevent them from breaking from the weight of the sand. Make sure to cover the hole in the top of the lateral assembly pipe with a cup or duct tape to prevent sand from going into the pipe. If sand gets into the pipe, it will come out into the pool. Don't forget to remove the cup or tape after adding the sand!

Just installed a hayward pump and followed directions on the pump having problems when we tried to backwash it shoots sand into the pool


Backwash should put no water back into the pool. It should be sending filter dirt to a waste line. Maybe your lines are incorrectly installed?
Secondly, under normal conditions, sand does not go to backwash waste either. Could there be too much sand in the filter?

Hayward sand filter needs primed every time


The problem is a malfunctioning check valve. It'll be somewhere in the line on the pump output side. If it's not a separate fitting it'll be in the line, probably in an elbow.

Need further info, let me know...
