Winterisation

For Correct Winterisation of Swimming Pool Pumps & Filters

Once Jack Frost turns up at the door it could already be to late to winterise – damage already being done.

Pumps:- If your pool is not heated all year round there will be a danger of frost damage over the winter months. It will be necessary to remove your pool pump or at the very least drain it down and protect it from frost & corrosion.

Once all the water has been removed from the pump body and the unit cleaned and dried it is advisable to lightly spray a tiny amount of WD40 or similar water repellent product down the output port of the pump. Using the spray straw normally supplied a light coating is recommended on the pump bearing this will prevent it seizing and sticking to itself over the winter months. Most pumps will have a slot at the motor end allowing a standard slot screwdriver to turn the pump a couple of revolutions every month or so to ensure it does not seize.

It is advisable not to store your pump in the garage or garden shed if it is not heated. Damp and corrosion not frost will be the killer here. When you are in the position to reinstall your pump in spring a quick flush with some warm lightly soapy water and a good flush with the hose pipe to remove all residue will do the trick to ensure months of fun and years of service.

Filters:- As with pump winterisation it is necessary to protect your filter equipment from frost. If your filter is not the removable smaller garden type that can be moved and stored you will need to drain what water you can from the system to prevent frost damage.

Ensure all stop valves are in the closed position and no water can escape the pool or flood your pump room. On some filter systems there will be a bottom drain that can be opened allowing water to be drained from the filter. If not water must be drained by syphoning directly from the filter itself. It is necessary to ensure all all water is removed from the Multi-Port Valve (MPV) these units are very susceptible to frost damage due to the high pressure frost can produce on a chambered device such as these.

If any pipework has been disconnected and open pipes exposed we would advise to seal with rags and tape to prevent any vermin finding a home for the winter. Clean the filter were necessary and when dry cover with some insulation for the winter months. It is worth a look in on your system every month or so to ensure all is well. Frost has a nasty habit of exposing any weak link in pipework and valves. A small tip – if you remove any O-rings in your winterisation routine take them into the house for storage, this will prolong the life and also give you the heads up if any need replacement.

Spring arrives and we would recommend to rinse and flush to waste the filter before use ensuring all pipework is clear while commissioning the pool for your summer enjoyment.
