Boiler Water Treatment
DOSING WITH MULTITREAT TS, TC & TV
Multitreat should be dosed directly into the cold feed water tanks. The precise dose rate will be difficult to define and will depend on the quality and hardness of the water supply. It's appreciated that without the use of chemical test kits and the variation of water supply dosing is very much guess work. As a guide we would suggest adding at the start of the season about a half pint (250ml) to the cold feed water tanks and allow this to feed into the boiler.
The amount of treatment can be judged by the colour of the boiler water in the gauge glass, which should have the appearance of 'Tea' or 'Bitter Ale', If the appearance is more like 'Guinness' or you can't see through it, then it is likely that the dosage is too high.
When the watercolour is weakened to that of 'Lager' it is likely you need to add further treatment to feed the water.
For model boilers we would recommend no more than a cap full to add to the water tank to start off or in a relevant proportion to these guidelines. Dosage is ideal at 0.3% or 3000ppm.
