Climate-Specific Tips
- Winterize all exterior water features (fountains, ponds, irrigation) by mid-October — Mountain West freezing season begins early and can be severe.
- Drain and blow out irrigation systems with compressed air — gravity draining alone often leaves residual water in low spots that freeze and crack pipes or fittings.
- Inspect heat tape on exposed pipes annually — Mountain West homes often have heat tape installed by previous owners; damaged heat tape either fails to protect pipes or presents a fire hazard.
- For vacation or seasonal properties, shut off and drain the entire system — leaving water in pipes during Mountain West winters in an unheated home guarantees freeze damage.
