Properly maintaining your backwash valve can extend its life for years. You can do this yourself, or you can have our professional staff perform this maintenance for you as a part of your seasonal maintenance package. Backwash valves have rubber seals or gaskets. There are several bad things that can happen to these seals or gaskets:
Make sure that your backwash line drains properly after backwashing the filter. If the line remains full of water during freezing weather, the expanding ice can break the pipe or even break the valve.
Backwash lines should have a drain valve built into them or have a hole drilled in them for drainage. Some backwash lines will naturally drain, but most will not.
