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.
Fuses only need to be changed when they blow. They are not a wear item.
wear shorts and a t shirt to the gym, swim suit to the pool!
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
They simply didn't see the need to wear clothes - they only changed after they were taught (by outsiders) that nudity was wrong.
you wear it
If the spots are under the pool returns and you have a cartridge filter of some sort then there may be a hole in the filter somewhere or a flaw in the seal that holds it in place. If the dirt is sand and you have a sand filter the laterals in the bottom of the sand filter may be starting to wear and need replacing. A more realistic answer would be that your pool has poor circulation and those "dirt spots" are eddys where there is little circulation so any dust, dirt, leaves, bugs etc that are in suspension just drop off there and settle to the bottom. Poorly designed pool hydraulics.
Yes. After several years the sand begins to round out like river stones and become less effective. It can also become caked with oils, calcium and other debris from the pool. How often you need to change the sand in your filter will depend upon different factors such as running time, water chemistry and filter size. A good rule of thumb is to change it about every 3yeats. When you empty the old sand from the filter, that is a good opportunity to check the laterals and other internals of the tank for wear and tear.
Just wash normally in hot water. I did not know that there was a rule. I wear my swimsuits to the beach and to the pool. Nothing has ever happend to my swimsuits or to the pool.
Many swimmers (in a pool) wear swimming goggles.
If you go swimming in a pool you don't need to wear anything but if you are going swimming in a natural waters like lakes, rivers, ponds, and oceans you need to wear water shoes (water proof).
a bathing suit....
I don't know where you got the idea for this, but it is not true. It preferred that girls do wear suit tops in a pool.
Brake discs or rotors need only be changed if they are scored or below minimum thickness. Pads will typically need to be changed about every 40,000 kms or so. Inspect for wear at least twice a year.
For the same reason you can only drink beer from a soup tureen. That is, there's no such restriction; you can wear sneakers pretty much anywhere you want. If you do wear sneakers on loose sand, you will probably get sand in them, but it's up to you how much that bothers you.
Yes, they still wear out. Most do last 100,000 miles though.
