Waste water freshness

Never had the need to use anything like that.

 

Just part fill the tank with a bleach solution, drive round a bit to slosh it all about and drain it out as soon as you stop before the gunge settles.

 

A couple of goes at that until the water runs more or less clear then a repeat with tap water to rinse out the bleach should get rid of any nasty niffs.

I had thought about using bleach. It would certainly keep the tank clean, but I don't think it would dissolve grease. Thanks for the suggestion.

Graham,

 

First tip, don't put FOG (Fats, Oil, Grease) down the sink drain then you won't have to worry about cleaning them out of the pipes and tank.

Pour all oil, and fat before it sets, into a container to throw out with the trash, wipe excess fat or grease off plates and pans with kitchen roll before washing them and NEVER, EVER pour milk (or even tea/coffee containing milk) down the drain.

 

If you still have a problem with smells from the plug holes then consider fitting waste traps such as those sold by CAK Tanks... Link (Look at page 26, we have type WD1425G fitted to our MH.

 

Keith.

 

PS And I find a bottle of Tank Fresh lasts at least 18 months and costs all of £6.75, surely that is a small price to pay for clean pipes?

Using a strong bleach solution to clean a motorhome's waste-water tank is a time-honoured method and will remove greasy deposits from within the tank as long as these are not caked on. The longer you can leave the bleach solution in the tank before emptying it out the more effective the cleaning process will be.

 

Other methods are regularly suggested on motorhome forums

and there are several commercially available products

These should keep a waste-water tank odour-free if used regularly, but, if the tank is badly contaminated to begin with, it would be best to address the problem initially using the bleach approach.
