    Maybe.... After following directions for Sanitizing my holding tank, I wondered how I could sanitize my hoses too. It would be nice if they included some kind of adapter to sanitize hoses! If it didn't kill my lawn, I would use it again.

    Fresh Water Tank and hoses

    What I normally do in the early spring is put chlorine bleach into the inlet of the tank. Then lots of fresh water. I then turn the pump on to get the blend up to the faucets (NOT THE WATER HEATER). After a few hrs I start opening faucets, turn the pump on and let it all go into the grey tank which I will dump later. IM gonna try CWS water treatments for after I have flushed out the chlorine. and leave it (Them) in for a week or so, depending on if I have used the Motor Home. If that seems to work Ill use it all season until Winter. Dont forget standing water can grow lots of nasty things. I do not drink any RV WATER so my concerns are different then others. To the person who inquired into hoses, I just use one that gets hooked up to 'flush' the black tank. There are attachments that can be found to hook up to a bucket and a faucet/hose I think it works like a Venturi?? to suck up whatever you put in the bucket to help you sanitize. I am very leary of water anywhere near the black side. Hope this helps someone,,,thanks
