Remember to Drain

If we get anything like last years winter you must ensure that you drain all the pool equipment when you close the pool. If you don't, you stand a high risk of cracking heat exchangers, pumps and filters. A costly and expensive exercise.
Boilers and heat pumps can be drained by releasing the pvc/abs unions that connect the heater. It is also prudent to cover the units with a tarp/sheet to provide weather protection. I have some customers that also get heating engineers to remove the burner trays.
The pump and filter will have drain plugs at the bottom of each which need releasing and allow the water to seep out. IMPORTANT - place plugs somewhere safe so you don't lose them in the spring.
Ball valve and union connectors should also be released at the same time.
