In nine years I've replaced the hose three times. The last time 4 years ago. Since then I double wrap the hose with this wrap. The wrap that comes from
Washworld turns one way and my local supplier's wrap turns the other way. Yes, it is expensive but it works great. I also make sure when the machine is in the middle the hose (including the wrap) is NOT touching the cross bars at the bend.
I don't know if that's just my imagination but it seems to work. The hose is currently 4 years old.
Hahaha...just said this and it will fail tomorrow
