If it is relatively new you should have a 71113T or 714T valve on top. This manual should answer your question. If not, please comment with how old the filter is.

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.

Can a Hayward s 166 t Hi rate sand filter be rebuilt


Parts can be replaced sure, but will it be worth it compared to buying a replacement or even upgrading. Laterals (if broken sand gets in pool) can be replaced on this unit from 48 off amazon and is cheaper than buying a new unit, same with leaking rings or seals. but if a part of the tank is cracked or something like that you might up spending almost as much to replace a piece of the unit as it would be buy a whole new unit. Amazon has this model for 180$ if repairs would cost more than 80 I would say replace it, these things dont last forever, especially if you live in a cold place that freezes in the winter and it sits in the sun all summer.

What size is the drain plug on my Hayward pool pump s166t


Most Pool Pumps use a 1/4" regular standard thread.
Thats pretty standard.
Now the filters from Hayward vary! They use a cap normally, and size is all over the board.

I have a hayward s166t filter, guage reads 0 and sight glass water does not swirl when backwashed


Does it show pressure when in "Filter" mode?

If not, then your pump is either not primed, Impeller is plugged, or there is not enough water in the pool, you are sucking air.

Hayward sand s166t. leaking from bottom


Are you sure it is leaking from a spot "Originating" at the bottom? Many times this is what is seen, but the water is actually traveling down the side.

If at the bottom, you either have a cracked tank, or the drain cap is loose, missing the cap gasket or it is on "Cross Threaded"?

But... most likely from experience, it leaking at the valve clamp.
