A practical down to earth lecture. My current sand filter was changed 15 tears ago but now I have problems. I placed 4 packages of 'Shockwave' in the pool to offset the heavy green coloring. Ran the filter for 12hrs, pool water almost clear. Next day: Heavy green color again! Next step: Change the filter sand!! Thank you, again.
Thanks for the video! I guess I am the exception to the rule with my sand filter. The sand has been in there for 15 yrs and it still works flawlessly. Right pressure. Water quality is here quite good not a lot of calcium. I am also quite surprised and check it regularly. Backwashing still works fine as well, I clearly see the water in the glass 100% clear after 2 minutes or so.
I've had my pool for about 12 yrs. and never changed the sand. Filter is still doing it's job. I must be a lucky man. I'm not looking forward to changing it when it needs it.
Kenny's back! Great Video. For part 2, if you none of you customers have sand filters that need to be changed, my sand is 7 years old and I'm on the corner of Lindsay and Ray 👍
Great explanation. Thanks for bringing up the access issue. A good builder will install the filter where it can be slid away from the equipment pad once it's partially emptied of sand. One that is caged in by pumps and plumbing is almost impossible to deal with and may run way over $500 to get changed. I wish the mfrs would innovate on the decades old design and put a 2 or 3 inch port low on the side of the tank above the laterals for easier emptying. Really enjoying your videos!
Hi Ben. I'd recommend following the manufacturers guidelines for speeds. Typically with my clients who have variable speed pumps I suggest for cleaning the pool, high speed (between 3000 and 3400 rpm) for 5 hours (peak season) or 4 hours (off season) and then lower speed to continue filtration (between 2600 to 2800 rpm) for an additional 3 hours (peak season) or 2 hours (off season). You may have to adjust that for your own pool but that's my general suggestion. Hope that helps.
My sand filter shows about 10 psi after backwashing. When it gets to about 13-14 psi it needs to be backwashed again (low flow shuts off pool heater and vacuum doesn't work). This filter is about 25 years old and never had sand changed. Do you think this is the problem?
Hard for me to say decisively. But I do know that typically in Arizona at least, when people run water through their heater it tends to reduce the flow and increase the pressure because of that. I think it’s because of all of plumbing inside the heater and the piping that has to go through, I think it restricts the flow a bit. Also, if you’re cool filter is 25 years old and the sand has never been changed. It’s definitely time to change it. Sand gets impacted overtime and clumps together so it becomes too permeable and the water passes through it too quickly to actually catch debris. Might I recommend you watch my video on the sand filter substitute that filters as good as DE. There’s a product out there that is a glass substitute for sand called Dr. Dryden’s activate and it is fantastic. Allows a sand filter to filter as good as a DE filter without any of the health risks of DE and it’s guaranteed for the life of the filter. You might want to consider a new filter altogether if it’s 25 years old
Hi Kenny nice to see you back. 👍🏽. Question for you. Please. If I add DE or soda Ach in the sand filter skimmer and come back to the pool jets. Is that and sand or broken lanter or whatever they call It. I appreciate your help and your answer
First of all you should NEVER add DE to a sand filter. Sand filters use sand to filter the water. DE filters use DE to filter the water. Soda Ash should be added to raise the Ph of the water and should be distributed around the perimeter of the pool surface. the reason you see DE or soda ash coming through the returns of your sand filter pool is because you SHOULD NEVER PUT DE IN A SAND FILTER. Nor should you put soda ash in the skimmer. Hope that makes sense,
Yes I understand Mr Kenny I seen some pools guys do that just to check if the sand is good or not. If DE goes back to pool they say that sand is not good or broken fingers that attached to standpipe.
Check the suction side valves of your system. Many times two skimmers is one skimmer too many so the suction is being split between the two. Usually there's simply not enough suction power from a single pump to created enough suction for both BUT check to see if you can adjust the suction to the skimmers to at least better balance them out.
are you asking how about using a degreaser in the sand? I’ve never done it and I would be hesitant to do so because of the residual of that degreaser getting in the pool water.
@@brandon367011 I would be hesitant and avoid using it with a sand filter. However with a cartridge filter a degreaser like simple green because it’s natural could be used to help remove the dirt from the cartridge filters but I would not use it on sand

@@Peter-Alexander glad to hear it. Thanks for watching and commenting.
Nice video Kenny. Can't wait to see the how to portion of this one!
Thanks for the response. I think it is time to step up and change the sand
Great idea.

Wow that’s a heck of a run.

Thanks for the offer. But the videos already done and will be posted this Tuesday. 👍

With a 30k gallon pool with a pentair system and a paramount in ground cleaner-what do you recommend regarding schedule and rpm for both pumps?

I have 2 skimmers and one of this is not working, what is my problem?

What about a degreaser

@@PoolSchooler yes !!! But if your hesitant I’ll just avoid it all together
