The threads are stripped on my Hayward sand filter drain plug.

The plug will go on but not tight enough to prevent a leak. I am thinking about using waterproof silicone caulk to clog the drain and keep the cap secure and just remove the caulk each year when I need to drain the filter. Anyone have a better solution or see any problems with my suggested solution?

I've had the same problem every year since I bought this house 10 years ago with my Hayward filter drain and finally MacGyvered a great solution. Went to Home Depot and bought a 1" PVC shutoff valve. The Hayward drain has an outside 1 1/4" thread. The part I got was an 'Aqua-Dynamic' 1" PVC Schedule 40(I can't find a picture of it on the internet). It is a white PVC valve with an inside thread that mates with the Hayward and a red shutoff winged knob. You need to hacksaw the red wings off the knob in order to be able to screw it onto the drain because the filter's base gets in the way. Leave the valve in the open position(especially if water is still draining with filter off) and put PVC cement on the outside of the drain thhreads and a bit on the inside of the valve and screw it on. When the glue dries(5 minutes), you now have a drain that you can open and close every year with ease(you need a pair of pliers because the wings are off the turn knob but it works great!)

My new Hayward Pool Sand Filter won't backwash.

The filter setting works fine, but when I set the filter to backwash, nothing comes out.

Hey!
Mine was doing the same thing. I had the hoses switched up. I had the hose from the pump connected to the port marked RETURN (on the Hayward vari pump valve). Not good! I also had the return line hose (from pool) connected to the port marked pump. It happens! The problem is I tried EVERYTHING ELSE before I found my error. This includes a trip to Leslie's to buy a brand new multi port valve (good thing they have a return policy) AND changing out my relatively new sand in the filter AND taking apart the vertical tube and each individual flange at the bottom to clean them out. Please check your hoses FIRST if it won't backwash! By the way...I've been a pool owner for 17 years. I think my experience worked against me since I didn't recheck my work at setup.
NOTE:
It might SEEM like your filter is working because you get suction at the skimmer and water rushing thru the return line into the pool. It's not working if your lines are backwards like mine were! My water started turning green!

Hayward vari flo valve

I have very little pressure from my filter from 0-5 when it should be 10-15. I think it is the spider gasket on the hayward vari-flo valve. I bought a new gasket but can't get the old one out. Is this gasket glued in? If so how do I remove it and what do I use to glue the new one down????? Thanks.

If the spider gasket in the vari-flo valve is no good, you will usually notice one of two problems.

1. Water leaking out backwash port while filter is operating.
2. Valve positions are really difficult to change.

The way to check this is if you are able to move one or two of the "spokes" in the gasket freely(out of the track it sits in) once the top of the valve is removed.

If so you need to replace. The gasket is usually held in with a silicone sealant. Once you remove the old gasket. You will need to scrape any remaining rubber from the track it sits in. I've found that a brass brush from a pluming supply store or home depot along with a flat head screwdriver is usually enough to do the removal.
I always used Permatex Blue RTV sealant on all valve jobs. It can be found at any auto parts store or sometimes Walmart. Follow the instructions for curing. Once cured the gasket is good as new.

How to change sand in Hayward S-200 Sand filter

hayward S-180 filter takes 150lbs, S-210 takes 200lbs not familur with the S-200. To change sand you have to remove the vari flow valve on top. You can either unplumb the filter and roll it over on its side and try washing the sand out or try scooping it out upright. Whatever you do dont damage the laterals on the bottom of the filter. When refilling with sand you want to make sure all the laterals are undamaged and in the down position. I always fill the filter half full of water to keep the sand from damaging the laterals while re-filling the filter with sand. Make sure you use pool filter sand and not play sand!

Hello, i just had a 3/4 inch open area develop close to the bottom of my sand filter. Apparantly the base rubbed it raw and the water was leaking like crazy. We called the pool place and they said they have never been successful in repairing a seam. Well we looked it up on the internet and there did not seem to be any real good solutions. . Our friend Ryan came over and he is an auto body man. he brought a tube of plio grip by valvolene #3. he mixed the two sides together and then got a putty knife and placed it over the seam. This stuff is unreal. So far in 24 hrs no leak. I think it is going to work. Everyone pretty much said we were going to have to buy a new filter. I will let you know later in the month how it goes.

No water coming out when I backwash. I cleaned

No water coming out when I backwash. I cleaned the filter basket at the pump, filled it back with water, and then tried to backwash. nothing. switched it back to filter and noticed water level was a little low. added water. could low water level prevent backwash. filter seems to run fine.

water level must be about the discharge (eyeball) in the pool to back wash. Check the hose connections to make sure that hoses off the the filer head are going to the right place Look for the words "Pump" , "pool" and "waste" molded into the valve. I've seen it a number of times where "Pump" and "pool" were connected the wrong way.

There's sand in my pool!

I winterized my pool by blowing out the line, and blocking everything off so there was no water in the pipes (avoid freezing)

This spring, when getting everything into operation, I noticed that there was a lot of sand (very fine, and brown) at the bottom of the pool. I vacuumed, and noticed that during vacuuming sand was blowing out the jets. I've run a backwash, and most of the sand is out, but a little showed up again. I'm concerned that something may be wrong with my Hayward sand filter

I have had this issue with several clients and before worrying, you might have had sand being drawn back into pool lines during winterization. this happens when you blow out lines, plug holes, but keeping it pressurized. if it keeps happening check draw fins on bottom of filter.

Unhook the plumbing from the multiport valve, hopefully you have unions, it would make it easier. Take off the multiport valve on top by removing the bracket, usually held on by two phillips held screws that go into corresponding nuts. After bracket is removed, carefully wiggle the valve straight up, Don't wiggle it side to side, the PVC shaft in the is like Schedule 20 and breaks really easily. After valve is off do not try and pull the shaft up, there is too much sand waying it down and you will break it. Remove the sand with a cup or pop bottle cut in half or whatever. It is a pain to keep scooping it out with the shaft in your way, but I emphasize the strongly, do not try to move the shaft out of you way or pull it out without getting enough sand out of there. The other way to get the sand out, a little easier, is use a shop vac. You have to do it slow and kinda jiggle the hose while sucking sand because it'll clog the hose up. Get all the sand out, pull the shaft and lateral assembly out. The newer laterals fold up kinda like an umbrella so you can remove it, the older ones you have to unscrew each later individually to remove it. Inspect the shaft and laterals thoroughly to make sure none of them are cracked or not seating properly. Spray everything off, reinstall the lateral assembly, center it in the filter as best you can, most of them don't lock into anything, they just kinda sit there. Put duck tape or something over the top of the shaft so no sand gets in it. Pour about 50lbs. of sand in, (usually 1 bag), and recheck the shaft to make sure it is centered. An S244 requires 300 lbs. but just double check the label on your filter. Pour it all in, take the duct tape off of the top of the shaft, slide the valve back on, lubricate the gasket on it first, retighten the valve via the bracket you took off. Hook the plumbing back up and you are good to go. Backwash it right off the bat for a couple minutes before putting it on filter. You can potentially blow dust into the pool if you don't
