I just opened my pool this week. Water was pretty clear. I use the vaccum, on waste with port 1 which leads to skimmer. I added chemicals yesterday....I was wondering when the pump is running regular for swimming and after putting in chemicals, etc.....what do i set the pressure valve??? I have a sand filter w/mulit port valves. I have the handle turned to filter but i dont know if i should have the other handle on full port 1, full port 2, off, 1/2,????

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...

Ok the first on the PSV valve. the 1/2 position should really be 1+2. You have two linlets to your pump. One from the skimmer and one from the main drain in the floor of the pool. When you select port 1 it will be one or the other perhaps 1 would be skimmer and 2 would main drain. You can select one and see if the flow stops in the skimmer. That will tell you which is which, depends on how it was plumbed. Position 1+2 combines the two flows. I normally select both, If my pool gets a lot of grass and leaves, I select skimmer only or when I vacuum. I select main drain only when there is more debris at the bottom. OK recirc is only recirculating within the piping system bypassing the filter. You can dowload a complete manual of your filter and components from www.haywardnet.com. Green water: Ok your chemicals are right? Free Chlorine, total chlorine? hardness, calcium, pH, alkalinity? Well most pool companies want you to buy some algaecide and that can't hurt, but I'd shock your pool if it's dark green I'd put it 4-6 gallons of liquid chlorine, if its light green 2-4 gallons. This is when I'd use recirculate. Allow this to mix without filtering for a couple of hours. Turn the pump off and allow to set overnight. In the morning you should have much clearer water, with green slime sitting on the bottom. Vacuum this to waste very gently so as not to remix algee.IF this doesn't work you'll need som floculant and repeat the opeation folling the directions on the floculant Restart filter, keep chlorine level high above 5-10ppm for a day or two and keep filtering. If it is still cloudy now,add some filter aid. In hot weather, don't let that free level go below 4ppm. Don't allow anyone to swim while chlorene level is high. Be sure to us test strips that indicate free and total chlorine.

SOURCE: We have a hayward sand filter and have replaced

There is more than one version of these valves. The model like sp072 has a 5 spoke spider gasket that has one opening larger than the rest. Be sure it is in position so that the large opening lines up with the large opening in the valve. If it's a SP0714 then the rubber is molded on the valve itself and would have to be replaced together. In either case, the seal is provided by the spring pressure forcing the valve faces together. That is why you should depress the handle, and only turn the valve while it's depressed, and the pump is off. After you turn to the selected location, then you release handle, and the valve surfaces should spring back together. Be sure the lever has spring tension on it in case you left it out while working on it) You can download complete manuals from www.haywardnet.com Good luck!
