Pumps, Filters & PVC Pipes - Won’t they ice up and crack?
Dependent on how cold your winters are, if you opt to keep the pond pump running, there will be a constant flow of water traveling through the PVC pipe, and the moving water will not freeze. Generally this applies to pumps operating at greater than 1,800 gallons per hour in areas with sustained below-freezing temps. Flex PVC and black PVC also hold up well, if not better than Schedule 40 pipe to freezing.
Most of your better pond filters, skimmers and waterfall boxes are constructed with durable, flexible materials which are designed to flex with the freezing and thawing of winter. With the smaller (and portable) canister style pressure filters, we do recommend draining and storing in a shed, garage or basement for the winter if you are not planning to run the pump. In extreme climates, storing a canister filter in winter is encouraged.
In areas that experience below freezing temps, water spigots and automatic water fill valves supplying basins, skimmers and ponds should be turned off to prevent pipes from freezing and cracking.
Pond Waterfalls - Will they freeze solid?
As we stated earlier, your pump strength is critical in determining if you can - and should operate it during the winter. A high volume pump (1,800 GPH or more), running continuously, can be operated throughout the winter. If conditions develop and the flow of water into the pond is unable to keep up because of ice build-up, it will be necessary to shut the system down. The system can be run again once the ice is melted and normal water flow is restored.
How about a pondless water features?
Proper pump care for a pondless water feature is necessary in cold climates that endure below freezing temperatures during the winter months. In these settings we recommend that you disconnect the pump, clean and drain it , and store in a dry place like a basement, shed or garage. We also recommend that the waterfall weir or spillway along with the basin be drained and covered to protect the hose-plumbing systems.
What do most pond owner’s do?
In our experience, the majority of pond owners in very cold climates opt to shut down their ponds during the winter simply because they can’t get out enough to enjoy it and the maintenance upkeep can be a challenge. If that is your situation, be sure to take the needed actions to support your fish over the winter.
