Yes it does. I've replaced my sand twice in 12 years. But I know others who have not. Depends on the amount of debri it has to remove and what type. I have too many nearby trees. I knew my sand was finished when the back pressure got so high it blew out the skimmer basket when it turned off. Replacing the sand takes a couple of hours. Good luck.
Sand needs to be replaced every three to five years. Proper backwashing and treatment with a sand revitalizer will keep your filter working efficiently throughout the sand's useful lifecycle.
If you are talking about sand getting into the pool via the pool returns then you are probably in need of new laterals in your sand filter. These wear out every so now and then and need replacing.
If you have a sand filter the laterals in it may be starting to show signs of wear these wil blow sand from the sand filter into the pool when they wear out.
No it either means you have to clean your pool more often or it can mean that the radials in your sand filter are stating to wear and need replacing.
For swimming you don't need to wear anything, for modesty you do.
NEVER wear tampons when not menstruating - it's not safe and no need.
Why would you want to? Sand doesn't wear out. Sand Filters don't do a very good job of cleaning Pool water Until they develop a layer of hair, skin and other debris like bugs etc on top of the sand. Even then, a Cartridge Filter and DE Filter do a much better job.
You can wear anything you want in a swimming pool
Sound like the laterals are wearing out these are the spokes at the bottom of the sand filter after time they wear out and don't stop the sand any more they will need replacing.
wear shorts and a t shirt to the gym, swim suit to the pool!
Fuses only need to be changed when they blow. They are not a wear item.
When they wear out. There is no set time to change them as they wear differently depending on how you drive and where.
people need to wear helmets to protect their heads from the damages
