Winter preventive maintenance

 Winter preventive maintenance  an ounce of prevention…

Who’s had to scrape the frost off their vehicles more than once this week?

December 1st marks the first day of the meteorological winter.

We thought it timely to remind those of you with water storage on site that’s aided by on demand pumps that it’s time to do some winter preventive maintenance to save inconvenience and damage to the pump.

If the temperature falls to 1 Celsius or below, you should take the pump out of service. Remove it from the water supply line, drain it and store it in a warm environment (indoors) until the temperature rises again.

When it comes to water pipework, we recommend lagging to minimise the chances of pipework freezing up. The pipework we use on site is 25mm dia and so 27-19mm lagging is ideal for the purpose.

Pipework will begin to freeze at around -2 degrees c. Pumps as mentioned earlier can be boxed in, but make sure the box has some ventilation.

Lagging should be applied to the whole pipework route, from the exit point of the bowser past the pump and into the cabin or appliance.

Bowsers themselves will rarely freeze to the point of being rendered useless due to the large body of water inside them.

Don’t be tempted to add anything to the water. You risk not only diminishing the quality of the water in your system and damaging the pipework and pump.

We publish a number of guides on maintaining and priming on demand pumps and the links are below. These can be downloaded in PDF.
