HI,

Can any of you experienced caravanners out there tell me best method to clean out sink wastepipe ( bit pongy) . We were toying with the idea of a weak solution of bleach but dont know if harmful to wastepipe.

Many thanks in advance .. Harry

Wouldn`t worry about the bleach.

I bung up the outlet and pour down a strong, very hot bleach solution, leave for 20mins and flush.

There are lots of different products on the market that are supposed to clean your pipes but some can leave a smell. If you use a product like Kemdirect descaler/cleaner it will clear you pipes of the bad smell but not leave any other smell in its place. It is also not harmful to the pipes in any way.

I sometimes use Mr Muscle foaming drain cleaner as described by Angus above.

I also put the pressure washer drain cleaner tube through the pipes a couple of times a year

You can get a water trap for caravan pipes from dealers for

Harry,

Smell from a waste water system is usually caused by kitchen waste (grease in particular) or bathroom waste (soap residues and hair).

These are best removed (dissolved) by using a caustic (alkali) cleaner - acid cleaners are ineffective. Your fingers are protected by a natural layer of oil, spill vinegar (acid) on them and you'll notice nothing - spill a similar strength solution of caustic and your fingers will suddenly feel slippery - the caustic has dissolved the natural oil.

A strong solution of Washing Soda dissolved in hot (60
