Wish to upgrade cartridge filter pump to sand filter pump. Pool size 15' X 48" / pump 1000 gph - 637R /Item no 56945 Which intex sand filter is the best one?


First, understand that sand doesn't filter as finely as cartridges, so "upgrade" may be the wrong word. Cartridges filter down to about 10 microns, sand filters to 25-30 microns. (i.e.the cartridge will catch particles up to 3X smaller than sand will.)

If you still want to change, get the biggest sand filter available that you can comfortably afford. For superior results look at above ground pump/filter packages built by Hayward or Pentair. Intex products are just built to margin and are not designed for long term usage.

Hayward h300 pool heater won't start


"LO" is simply informing you that the Heater is not sensing proper water flow through it! A Flow Problem.
A special sensor, called a pressure switch is this source. But... That does not mean it is bad - No, it is in most cases just doing its job!
Most common reason - Dirty Filter.
A good cleaning of the cartridges, or maybe a breakdown and recharge of a DE Filter, or a good cleansing backwash of your sand filter, will remedy this situation.
Or... Check for any OTHER reason or situations water flow may be reduced through the heater:
  • enough water in pool or spa?
  • If you have a weir gate in skimmer, is it stuck in the UP position?
  • Are any valves closed?
  • Do you have a bypass valve at the heater?
    • If open, this will reduce the amount of water going thru heater, close it to the point, LO goes away.
  • Could be debris in front of Pressure Switch, in the copper tubing
    • Unscrew and remove pressure switch, turn pump on. But first, align end of tube so that when water squirts out it will shoot out from heater and not onto electronic heater components!
  • If all above is good, you may have failed pressure switch?
  • Etc
Good Luck - hope this helped.

My hayward sand filter is running but not filtering or doing anything pressure on gauge is not moving and i checked for clogs nothing can someone help me out or let me know where to start.


Is the pool pump working? If not then the filter won't work and no pressure will show pressure.
If the pump runs, is it flowing water through the filter? If the backwash valve is not set to "FILTER" then it will not filter. If it is not working yet then please send me the results and I will try to figure it out. Thank you.

I have a Hayward 160T high rate sand filter. How often should the sand be changed? Can you over shock a pool when you first open it? What type of sand and where can I get it?.


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.

When vaccuming the pool the dirty water is comming back in the pool through the filter. I backwashed till clear. At first the water is clear but after several swipes with the vaccuum the water starts...


if the debris your are trying to vacuum up is more fine than the sand can catch (specifically with algae or dead algae), it will blow right through the filter. there is a setting on your filter called either drain or waste. when using this setting the water completely bypasses the sand and comes straight out the back wash outlet. this is a rather tedious task as you lose alot of water, but it is the only way to remove this type of particulate. make sure the pool is overfilled when you begin. good luck!

I'm having a problem with my Hayward multiport valve. Until recently when I changed the sand in the filter, it was working fine. Now that I've changed the sand and cleaned the valve, the valve is not...


If you just removed the multiport valve to do the sand change and did not take it apart, there should not be any problems. You may need to take the multiport valve apart to see that the spider gasket is in place. Also, if you did not fill the tank with water up to the level of the laterals at the bottom before adding sand, you may have broken a lateral and it's allowing sand to return to the pool. I would check the spider gasket first. Also check the spring and stem to make sure that it is actually changing positions inside.

HAYWARD SAND FILTER, PRO SERIES: sand is getting into the pool whan the filter is r...


Have you tried backwashing recently? If so, I would first check to make sure that your pool filter is on the "filter" setting and has not been changed. Next, i would evaluate your filter pressure to make sure that it is at an acceptable level. Finally, check your sand. If it is extremely dirty or has not been replaces in a long time, it might be time for fresh, more effective sand.

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!
