Q & A

pump out toilet odour

Not sure if you can recommend a product that will eliminate pump out toilet odours (I haven't found one yet!) - but do you have a suggestion for an effective product?

WW says:

It tends to be the simpler types of pump out toilets that have the greater tendency to smell, with the dump through being at the top of the list.
If your toilet is smellier than it should be; it may be that the seals are getting perished or are damaged. Replacing them might make all the difference.
The other important item that is often overlooked is the vent; check that the tank vent pipe is not crushed and that it is not obstructed in any way. Sometimes the pipe can get blocked with spider's webs and debris, stopping the free flow of gases.
Ventilation within the bathroom will also aid the dispersal of smells; there is usually a mushroom vent in the ceiling of a bathroom, but good airflow will be aided by the provision of low level vents or a gap below the door.

If you are looking for a toilet fluid that will kill smells in the tank, I can thoroughly recommend Odorlos. We have a dump through toilet and used to empty the tank (as well as we could) and add some 'green' fluid at the end of the season. At the start of the next season, the remaining contents of the tank would start to smell shortly after we set off. Since switching to Odorlos, this has not occurred at all.
I don't know how good it is at killing bacteria but it certainly kills smells.
You can buy Odorlos at large candlers and a 1 litre bottle, which treats several tankfuls, costs around £11.00.

I have just checked the Odorlos bottle and it says that 25ml will treat 90litres of tank capacity so it's fairly economical.

Odorlos works by helping provide an oxygen-rich set of conditions, which help aerobic microbes to flourish, which both help prevent odours develop and also encourage breakdown of the waste. It certainly works effectively, and by encouraging aerobic conditions, anerobic organisms are reduced and so the bad smells.
However, if you change from other materials, I would suggest a thorough flush-out of the tank with water, to remove any remaining previous treatments (especially if you have used formaldehyde based "blue" at any point) and consider a double-dose (if appropriate) for the first one or two "tank loads" of effluent.
