I have a Hayward sand filter and its leaking from the bottom. I know this because water is collecting under the stand it sits on. I can't move because of the plumbing. What do I do.

Depending on how close the pump is to the filter, you may be getting tricked and the shaft seal in the pump is leaking. If the bottom of the filter is leaking, it's either the drain plug, which is obvious and you can see it. Or the tank is cracked because it wasn't winterized properly, depending on your situation. There is nothing else underneath that filter that will leak. You need to locate exactly where that water is coming from. If it is the shaft seal in the pump, it is hard to see but look underneath your pump where the plastic housing meets the motor, the shaft seal is in that area, although you can't see it because it is inside the pump, but if it is leaking, that is where you will see it. Need an update after you check that stuff out.

What will happen if the stand pipe o-ring is bad?


The Hayward Pro Series Sand Filter uses an O-Ring on the stand pipe to separate water returning to the pool, after being filtered, from water coming into the filter from the pool. If this O-Ring is broken, missing or sufficiently worn, small particles of dirt and sand can by-pass the sand filter and return to the pool without being properly filtered by the sand filter.

This can be especially evident just after backwash and rinsing of the sand filter bed. During this time water flows up through the sand bed, opposite the direction in normal operation. This forces the top-most material of the sand bed to dislodge and wash out of the filter to waste. It can also force fine particles to enter through a faulty O-Ring into the pool return stand pipe. Then, when returning the filter system to normal operating mode, those fine particles enter the pool through the water return piping and collect on the bottom of the pool -- mostly small sand particles but potentially filtered debris particles that were captured on top of the sand bed.

To avoid this problem it's wise to replace this O-Ring every few years. And make sure to follow the manufacturer's recommendations regarding the amount of sand to fill when replacing sand. It's important to keep the top of the sand bed at the correct level to insure proper filtering and minimize stray particles coming back into the return water.

My filter has only been used for 2 months, it seems like there is sand on the bottom of pool, I just had new liner put in because the sand crystallized last year and I couldn't get it off. The filter...


Hayward should stand behind their filter. If the unit is only two months old, the seller should be helping you. If there is sand in the pool, it is because on the bottom of the filter is a distributor which is tubing with many thin slits. The slits are small enough that sand can not get through. If a piece of the tubing breaks or if it is not installed tightly, sand will continue to get out and into your pool. If you Google Hayward, I'm sure customer support will be able to help you.

I have a hayward sand filter. Do I fill the filter with water also, or just the sand?


Fill it half-way with water, cover the stand pipe coming up in the middle so sand cannot get into it, fill the tank with the sand (only use the amount the label says the unit takes), then install the valve and piping.

Sand being returned to the pool after vacumming through filter


This could be caused by several things. . After back flushing,did you rinse? Turned pump off, moved selector to rinse, and allowed to run until clear water was observed in the sight glass? If you continue to see the plume of particles, and it never stops, then you probably do have a problem. Your multiport valve gasket could be leaking by. Be sure you keep handle down when moving valve, and the gasket will last longer. You may have a broken, lateral (little fingers at bottom of the filter return piping. This would usually allow sand to flush out of the filter and it would be all the time. The "O" ring where the multiport valve seals to the down pipe could be leaking, letting the dirty incoming water mix with clean outgoing. Have you "cleaned" your filter lately? This is where you add a chemical to flush materials from top of sand pack? You can download a manual with troubleshooting instructions from www.haywardnet.com Enter your exact model number

My hayward s230t sand filter is leaking out the backwash and multiport valve is on filter but the water is recirculating it's not being filtered.


If you remove the top of the valve you will see a spider gasket that has pulled out of place. remove this and clean and dry throughly. Add a small amount of silicone sealer to the bottom of a new one and install in groves then replace top of valve and let sit for a couple of hours. That should fix. If not you will need to replace the top half of the valve also.

Will a 240 hayward sand filter with the SPX0710X32 valve, allow


If they are to much for the pump basket you can try filter by-pass. Another thing could be a tool called a leaf master that hooks on your garden hose and sweeps any and all light stuff from pool and collects in a bag big enough to hold it all in one sitting.

Sand in my waste water


O-rings or gasket are replaced to stop leaks, so that wouldn't have helped you.

It could be one of two things; either the white PCV-like pipe in the filter tank is cracked OR some of the laterals at the very bottom of the tank, under the sand, has melted. A whole new underdrain assembly is usually $70.

Sand shoots out of my return flow when I turn on the filter. Why?


It could be any of the following.
1. If you recently added sand into the filter Sand might have been poured in to the standpipe when being added to the tank.
2. A broken or worn out lateral . (One of the slotted tubes) on the bottom of the tank that water passes through on it way back to the pool. A lateral acts as a strainer keeping the sand in, lets the water out.
3.. A cracked standpipe the tube that sits in the tank, connects into the filter head
4. Filter head O-ring maybe dislodged. It's located where stand pipe connects, to the filter head inside the head.
5.. The hoses on the filter maybe hooked up backwards. The hose going from filter to pump may be connected from filter to pool.
