Don’t Let a Freeze Destroy Your Investment
Colorado’s winter temperatures can drop fast — and if your water feature isn’t winterized correctly, ice can damage pumps, crack lines, and ruin rockwork. Whether you have a pond, waterfall, or bubbling boulder, here’s how we prepare systems to survive the freeze without costly spring repairs.
Different systems require different winterization steps:
Pondless waterfall: Easier to drain and shut off
Ecosystem pond: May need partial winter function to protect fish
Formal water features: Often built with autofill, requiring valve shutoffs
We always assess the installed system before creating a winter plan.
If your system doesn’t need to run through winter:
Unplug and remove the pump
Store it indoors submerged in a bucket of water to prevent seals from drying
Blow out or drain supply lines if accessible
Disconnect auto-fill or irrigation lines to prevent cracking
If the pump must stay running, we insulate pump chambers and monitor regularly.
For pondless systems, drain the underground basin as much as possible
For ponds, lower water level just below the skimmer opening
Remove debris from the bottom to prevent sludge and anaerobic buildup
If fish are present, add a floating de-icer to keep an opening for gas exchange.
Leaves left over winter create sludge, clog pipes, and breed bacteria. We recommend:
Netting the pond in late fall
Vacuuming or manually removing leaf debris
Trimming back pond plants before freezing
These lines often freeze underground before the pond does. We:
Shut off the backflow preventer
Blow out the lines if possible
Cap exposed connections with winter plugs
This helps prevent spring flooding and cracked fittings.
Any exposed PVC, flexible piping, or check valves should be:
Fully drained
Wrapped with insulation or foam
Shut off at the valve box if applicable
We’ll inspect your system, shut it down correctly, and make sure it’s protected until spring.
