20 Most Recent Hayward SAND FILTER, PRO SERIES Questions & Answers


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!

Hello, 1 You need to unscrew the drain plug and screen (if it is still there!) at the base of the filter. 2 You can reclaim most of the sand by letting the filter drain through a sieve (lots of work) or use new sand. 3 Uncouple union joints or couplers that attach to filter head. 4 Remove filter head. 5 You can try pulling some sand out of the top. However, do not damage the filter fingers in the sand. 6 Use a hose to blast the sand out the bottom drain. 7 Inspect all fingers, replace if necessary. 8 After all is cleaned out, place finger mount inside filter. Cover top of mount with a cup or similar to keep the new sand out of the finger assembly. 9 Replace drain plug and screen. 10 Fill filter halfway with water. 11 Slowly pour sand in and spread evenly. 12 Remove mount cover. 13 Reinstall head, unions and couplings. 14 Prime pump and test for leaks.
Good Luck

You can try different epoxy's but they usually won't hold as the filter expands when running this will break any seal where you put it.You can check into warrentys. A lot of these filters had good warrentys on the tanks that went longer than valve or internal's. if you have install dates and model #'s. Check on line with Hayward.

Worse comes to worse you can drill out a small hole amd using stanless steel go with a bolt and nut with washers and rubber washers in the middle. when you set it seal it all with silicone and after it is tight let it set for eight hours or so. Good luck.

i always start a new filter in backwash mode. that way, any dust will be washed away and not into the swimming pool

from what i can find, it will take 350lbs of sand. there should be a chart on the actual filter housing

Hayward SAND... • Answered on Jul 26, 2019


put the housing on the base (level) and make sure the three 'locators' on the bottom of filter housing are resting inside the base ring. put the standpipe into the housing and install the 8 laterals. make sure the standpipe is straight and centred in the housing (i use duct tape to block the top of the standpipe and secure the standpipe to the housing. fill the housing roughly halfway with water. slowly pour sand into the housing making sure to keep the standpipe centred. once you have installed the correct amount of sand, install the dial valve and secure it with the supplied clamping system.

pool manuals are available on amazon

I believe that the owners manual has a parts listing to help you distinguish the part that you will need to buy. However, if your pool filter was purchased in 1990, you are probably going to need a new filter. Most do not last over 20 years.

The spider gasket inside the 6-position valve is probably leaking. Take the model number of the valve to a local pool store and they can order a replacement. You will also need a special sealant to install the new gasket.

You could have a seal leaking in your pump, the lid could be loose, or possibly a drain plug on your pump. You may need to put a check valve on the suction line

the trick is to start with the pump pulling from the main drain, you will see air pocket in the pumps basket (most cases) turn the valve back slowly towards the skimmer as soon as you see the air pocket disappear, You have the perfect blend between the two sources. and a happy pump.

You will find a huge price difference between Amazon and a pool store. The valve is about $100 from Amazon, about $250 at my pool store.

Check the standpipe gasket. Its a small part, but could be the problem. Also, look very closely at your manifold for any small cracks. The smallest fissure in the manifold can produce big problems.
