Most new pool owners have no idea what “backwashing” is and will have no idea what a backwash hose is either, so this mini plumbing lesson will show you and explain to you where and what the backwash hose is.

The backwash hose connects to the backwash valve on the swimming pool filter and then will get rolled out every time you need to backwash your pool filter.

How Often do I need to replace my backwash hose?

The answer to that depends , if you have an above ground pool and use a common flexible hose they usually only last a few years , if you are using an underground line that is plumbed in with hard pipe , then as long as the pool is closed properly during the winter the backwash like should last the life of your pool.

Yes you can, just be aware that the DE or the debris could wind up all over the filter area, its best just to go out and buy a new backwash line.
