Sandy pools

[Hayseed]

I have seen quite a few postings where sand has been found on the pool floor? And I was wonder, if after the line left the filter to the pool, if within that stretch you insert a t fitting and have a down pipe connected the longer the better, with a clean out at the bottom, do you think sand leaving the filter would collect at the bottom of the tube, as the sand is heavier than water, or is the force not going to let this happen?

I see where you are going, but I think a good amount of sand would still go past and into the pool. I say that because at the point of pressurized released at the filter outlet, the water is pushing quite hard. Any sand getting past the laterals is suspended with the water and will blow right on by. Now once the water has exited the return jets, most of that pressure diminishes quickly which is why it's so common to find sand fallen in the area of the return jets.

Is the sand on the pool floor a danger to wearing out the liner faster? Due to being stepped on and ground into liner? Or is it just a comfort thing to get it out?

More of an inconvenience really having to vacuum it out. If enough were to get blown out of the filter over time, I suppose the filter (sand) level would get low.
