Remove the old sand in the filter and replace the broken latterals and add new sand as per mfgr's specs.
Filter it then swim in it.
I have an inground spa when I turn on the jets they start then stop. I have put pressure in the line nothing clean the filter nothing. What can I do
Need to rephrase question.
You may have a new pump and motor, but it sounds like the internals of the filter itself are broken and should be either repaired or replaced.
Hmmm, do you possibly mean the back wash valve on the filter? This valve has many positions to choose from especially for sand filters. Filter, back wash, drain, drain to waste, filter bypass, closed. They are pretty much self explanatory. Normal position would be the "filter" position while the pump is running and the filter is working. Ken
The amount of DE (diatomaceous earth) needed for an 18x36 inground pool filter typically ranges from 1 to 2 pounds per square foot of the filter's surface area. To determine the exact amount, check the filter's specifications, as they often indicate the recommended DE amount. Generally, an 18x36 pool may require about 4 to 6 pounds of DE, depending on the filter model. Always consult your filter's manual for precise guidelines.
MY inground spa jets are not plugged. You could have asked the question: MY spa jets are plugged or seemed to have stopped functioning what is the cause?Try cleaning your filter. Try emptying your pump or skimmer baskets. k
If dust is coming from your air conditioner, you did not put in a filter. You will ruin your air conditioner running it without a filter. Also, the vents will get dusty. You need to clean them.
If dirt returns to the pool while you are vacuuming, it means there is a hole or broken item in the filter. If filter is a cartridge filter the could be a hole in the cartridge. DE filter, hole in filter fabric or broken plastic manifold. Sand filter - broken plastic fitting maybe.
Not keeping oil in it, not changing the oil and filter, not servicing the timing belt when it needs it, running it without coolant.
