Besides wanting to shoot the pool, I need to fix it. Why do I have sand coming out of the jet into the pool?

Its never done this ever and I've had it about4 yrs now(it came with the house when I bought her) I was showed by the owner how to clean it and take care of it, so after three on holds on the phone at my local pool guy I thought I'd ask here and get a quicker answer

I assume you have a sand filter ? : I know, I know where else would the sand come from ?

I have one of those Intex steel frame Kwikset pools. I upgraded to a sand filter. Inside the filter under the sand is a strainer assembly. It's connected to the valve assembly via a length of hose (all of this is inside the filter).

Sounds like perhaps one of the hose clamps failed OR the strainer failed allowing sand to be pumped into the return.

s the flow of sand constant or just at filter startup ?

Either way, you'll probably have to tear it down to inspect it.

Like said before : Sand Filter: Did you back wash it recently??

or

You have a hole in your liner, perhaps in a floor seam and sand is coming in and going through the fiolter. Are you loosing water or filling your pool more than normal?
