SOURCE: Does the Hayward GM-245 Sand filter tank separate

I am not that familiar with the G series Hayward filters, but most sand filter tanks do not separate. It's a labor intensive job so think hard before trying it if you haven't before. If your backwash valve is on top of the filter, the plumbing will have to be removed. There are two ways that I have removed the sand. Scooping it out by hand or using a shop vac. Remember the sand is going to be very heavy when wet. You will need to go through the top. Some filters have a large drain plug in the bottom that "supposedly" you can drain the sand out through.I have done this once and it makes a big mess that you still need to clean up.

Be sure to buy replacement o-rings and gaskets as needed. There is also a product called a sand vac that is in essence a siphoning system.

Be careful not to damage the laterals it the bottom of the filter. When replacing the sand, I put small gravel (pea gravel) carefully under and partially around the laterals to help support them from the weight of the new sand.

When you are done, be sure to backwash the new sand to remove dirt, impurities, etc. This is a general overview. There are books online that give more detail or use a similar filter's manual...

SOURCE: How do I replace the

Replacement of the sand is easy but there are a couple of things you want to do first.
Make sure you have a good shop-vac, get gloves, and purchase the proper sand.
This sand filter calls for #20 silica filter sand. (this will be available online, at your pool store, or at any water treatment facility).
Here is the link for this filters manual, and for the brochure (which has good pictures)
http://www.waterco.com.au/CMS/uploads/brochures/ZZB0512_Thermoplastic.pdf
http://www.waterco.com.au/CMS/uploads/Manuals/Sand_manual_829006.pdf

The manual has step by step instructions on filling and starting the filter.
The only part it doesnt tell you about is how to empty the old filter media.

To start this:
1. turn off circulation pump
2. Bleed any pressure or vacuum from the system using the bleeder valve, or just rotate the multi-port valve.
3. Open the drain valve at the bottom of the filter if there is one (some dont have one)
4. remove the collar between the multiport valve, and the tank. (this should be 2 phillips head screws)
5.Remove the multi-port valve.
you now have access to the sand.
6. Remove sand by whatever means (either a scoop or a good shop-vac with a thick hose)
be sure to be carefull once you get 2/3 of the way down the inside of the tank. There are LATERALS down there that are most likely brittle from chlorine.

Once sand is removed check and clean the laterals at the bottom of the tank.
Clean and flush the filter body and follow the directions in the manual to fill and start-up the filter.

If this helped, please vote positively for me.

SOURCE: when waterco sand filter is

Thank you for posting your question here on Fixya.com.


Since you already replaced the gasket you will need to check two others things: First, inspect the groove the new gasket is sitting in as well as the mating surface of the diffuser. Be sure none of the old gasket is still there. Thoroughly clean all surfaces as well to ensure the new gasket is fully seating in the valve. If that does not cure the leak you will need a closer inspection of the mating surfaces to find a crack. Without any pump pressure on the valve it will be tough to find. It will appear as a hair like line but once the pump is on it will open up enough to let water pass. If you find a crack you can try to use a two-part plastic approved epoxy to seal it or else you will need to replace that part.
