carpet cleaners use 50mm hose so most CC supliers will sell it.most carpet cleaners also change it often as it gets dirt and we have to use it in customers home....so always like it to look clean and new. so if you ask in the carpet cleaners section you might get someone to sell you some old hose which would be ok to use outside with a guttervac
The omni pole hose is expensive for a reason, it's virtually indestructible and will last years.For cheaper stuff goto century hoses, you can get 2" pvc spiral helix. It's lightweight but only last for a year depending on how busy you are.Darran
If it's wire reinforced should be good, but I thought omni vac were selling theirs for £110 a while back ( I know it was on special offer ) but the polar vac should be okThe vac hose fits to the bottom of your Ali or carbon tubes does it not Height shouldn't be a factorDarran
