Same as any sink. The vacuum breaker installs in the backwash unit. Just plumb in hot & cold, and plumb out a drain line.
Everyone has backwash.
it is in a normal drain
On your typical sand filter the water basically goes in through your multi-port valve and works down through your silicat sand (Filter median) and into your laterals to your pool or spa. During backwash, the water is taken from your spa and ran through your laterals first and agitating the silicate (filter median) and pulls most of the "waste" that was trapped by your filter and flushes it out through your drain hose off your multi-port valve. This does two things, one of which was mentioned prior and the other is that it agitates the sand in the tank and removes any channels that have been bored from water being pulled down from the top. It cleans the filter median as well as gives a reguvinated filter without pitting or "worm holes". You can also use a cleaner that you put into the skimmer basket and shut off the main drain lines and backwash as normal. This helps remove some of the soaps and fats that are attached to the filter median and don't get agitated loose through normal backwash.
The amount of backwash in a beverage is around 10%
how do i calculate the volumn of backwash in a pool

If you mean you are losing water, it may be a broken or cracked main drain or possibly your hyrdo-static valve is malfunctioning. One other possibility is a break in the pipe going to the main drain.
It is not possible to remove a tub drain without using any tools. Tools such as a drain key or pliers are typically needed to unscrew the drain and remove it from the tub. Attempting to remove a tub drain without tools may cause damage to the drain or the tub itself.
You can set up a siphon hose if your pool is on a hill, otherwise, buy a pump. Hatawa
It's a floor drain without a strainer that you can run other drain lines to, such as the drain line from a freezer in a supermarket.
