Intex Sand Filter - Just pooped in my pool!

[BigDave]

I can only imagine that it found/dug a path/tunnnel around the sand and washed all the crud from the top of the sand out to the pool. Maybe there is some type of overpressure relief.?
Can you open the filter and visually inspect the sand bed? are there channels through it or is it even?
Since it's working now, keep a close eye on it when vacuuming. Can you vacuum to waste? You'd waste the water but keep the crud out of your filter.

Well, I took the lid off of the filter and the sand looked all even. Checked everything out, nothing looks broken etc.

Put it all back together and back flushed real well, then rinsed and it's working good.


My neighbor had a thought.


Maybe it sharted.

Maybe it had air in the tank that needed to be passed out and it bubbled and stirred up all the crud.

I dunno. It's working great. Almost has the water clear again after yesterdays catastrophe.

We will see!

Thank you all for the input. I'll keep you all posted if I figure anything out.

I had the same thing happen to me with my sand filter about a month ago. The problem was that I tried to start vacuuming but had too much air in the line. Now I know to put the hose in front of the return line to fill it up with water, so that doesnt happen anymore.

I was going to comment like one other that maybe it had to do with some air getting in there and causing a small "explosion" in the filter. I have had my sand filter for 12 years and have never seen anything like that although I'm not so careful at times to bleed air out of the lines and such like I should. Does your vac just connect into the skimmer with the skimmer basket then the pump strainer in line with the filter? You mentioned a new pump, is it a higher horsepower/volume pump than you had before?
