Protect Your Pump this Winter

10th December 2015 by David Critchley and Sarah Sinclair


With the recent, un-seasonably mild weather, it’s easy to forget that we need to protect our pumps from the perils of Jack Frost. When the temperature drops; and it will, here are a few tips to protect your pumping system from damage.

1)  Insulation is key. Insulating your pump gives protection against the cold to stop your pump from freezing. A simple way of insulation is to wrap the pump in bubble wrap (taking extra care to not restrict the airflow around the motor).

2)  Keep thpump switched on. Allow the pump to keep running by leaving a tap partially open. This will help to protect against freezing but you must be careful not to run your pump against a closed head as this will cause it to over-heat.

3)  Drain the system. All pumps have a drain plug at the lowest point. Be sure to remember that any pipework or control equipment will need to be drained too.

4)  Heating.  If temperatures fall significantly and your pump isn’t insulated. Have a small heater set up close by which will protect the pump against freezing.



For water wells in particular, it is important to remember that frozen pipes or control systems can damage a submersible pump if it does not switch off. There are a few different steps you can take to protect your pipes from freezing this winter:

1)  Insulate. Lag the pipes and control equipment.

2)  Install. Heating

3)  Cover. Make sure that the well is covered up securely.

4)  Drain. If you cannot protect the system, drain it down.

Don’t get caught out, act now to eliminate any unnecessary costs and problems during the winter months.
