When to replace sand filter medium - Pool & Spa

rp2100 is a pool heater by raypak it has no filter. you need to clean the filter whatever type it may be. sand/de filters can be taken apart and the medium takin out and replaced, while cartridge can be taken out and sprayed with a hose and put back.

It is called diatomaceous earth for pool filters.

if the centre pipe can be matched to a pvc pipe size then the next problem to consider is the hole size or slots to allow the water in or out of the tube
filtration works by passing water through a medium ( sand ) and out back to the pool
You may get around the problem by grinding slots or drilling holes in the pvc pipe and securely wrapping fly screen mesh around the outside of the pipe to retain the sand

When sand comes back from the filter, that means that the device inside the filter that keeps the sand in has broken. In order to replace the item, all of the sand must be removed and the tubes must be removed and new ones installed. Go to your local pool supply house with your filter information and they can show you how to remove your old units and they will sell you new ones. You only have to replace the ones that are broken.

There is only one thing that can cause sand to come back into the pool from a sand filter. The internal assembly, called the lateral assembly, is either cracked or broken. This is an easy fix and should cost you around $70 to replace the whole thing. You need to unscrew the bottom drain cap on the filter to remove the water in the tank. Then, remove the multiport valve on top of the filter. Take a shop vac and remove the sand in the filter. If the sand hasn't been replaced in the last 3-5 years, this would be a great time to do that since you already have the sand out anyway. Then, remove the lateral assembly and inspect the entire thing. After you replace the lateral assembly, you'll need to fill the sand filter tank 1/2 full of water before adding fresh sand. This is done to cushion the laterals from the weight of the sand. Cover the hole in the top of the lateral assembly pipe with a cup or duct tape to prevent any sand from getting inside the pipe (the sand will come out into the pool if it gets into the pipe). Fill the tank 3/4 full of pool filter sand. Make sure it is genuine silica pool filter sand from a pool company. A lot of big box and home improvement stores sell play sand as filter sand. This will cause you more problems!

Q. I have a Hayward 160T high rate sand filter. How often should the sand be changed? Every 3 - 5 years.

Q. Can you over shock a pool when you first open it? Only in the sense that a liner or some of the equipment will not like ultra-high chlorine levels and depending on the shock used you can mess up pH and Alkalinity...generally you shock with one pound per 10K gallons.

Q. What type of sand and where can I get it? #20 silica sand...some places will call it fine sand. Do not use the coarse or medium coarse sand.

You will need to remove multiport valve and remove all the sand with a scoop. Not alot of fun. Think about replacing sand with ZeoBrite filter medium when you put it back together

if u used play sand, or any other type of sand thats NOT pool filter sand, that could be the problem. also if there is too much sand or too little sand that could also cause this.

sounds like the sand has clumped together inside filter. you can open filter and replace sand charge or dump into wheel barrow loosen sand and flush clean with hose and put back in
