We have a problem with a very strong sulphurous smell from our water when you turn the tap on. Any ideas and cures please.

Where do you get your water from and how is it stored?

Hi Gordon. We are on the road full time in our 9 mtr bus and get our water from taps wherever. Obviously we have an on board 200'litre tank. It is odd as the smell is not always there even when on the same tank fill. The smell is very strong when it occurs and happens as soon as you turn the tap on. Cheers Ross

It sounds like hydrogen sulphide which is caused by the microbial breakdown of organic matter in the absence of oxygen. The grey water tank is the most likely source of this smell, are you sure its from the tap and not the plug hole?
We occasionally get a similar smell in our bus and have tracked it down to air from the grey water system coming back up through the drain(s)

For piece of mind I'd also give the fresh water tank a bloody good clean out and see if that fixes it. You may have picked up some less than pristine water from one of your fill ups.

Cheers

Do search through this forum as there has been topics on tainted water. Someone may be able to find them?
I would be dumping the lot when you can and using one of the known treatments for purifying along with a known source of fresh water.

If it is in the water, do as Beanpole suggested. It also may be worthwhile installing a drinking water filter with an activated carbon element to remove the smell.

It could be an interesting exercise to write down (as far as you can remember) all the places that you got water supplies from since before the problem was first noticed. How many of them were from country service stations or small towns that may have had dodgy untreated water? It might be worth avoiding all of these as far as possible and just getting your water from places that have treated, or at least tested supplies.

If it turns out that a smelly drain is likely, then a dollop of drain cleaner and sanitiser down the plughole last thing at night might help.

This http://www.nzmotorhome.co.nz/forum/view ... on#p129012 will provide some info on decontamination.
We carry a portable inline filter with a 0.5 micron silver impregnated activated charcoal cartridge and every drop of water that enters our van passes through this filter first. Peace of mind and it does take out the strong chlorine taste found in a lot of town water supplies. We replace the cartridge every 12 months ($45)

Thanks everyone. It is definitely the fresh water. Will be back to base next week so will clean the tank and add a filter. Cheers Ross
