Frequently asked questions

What should a West Covina water heater quote include?

The permit, two seismic straps (state law), venting checked to current code, a drain pan where required, and haul-away. In a city a 1950s–60s San Gabriel Valley boom suburb, expect legitimate code-correction line items on older installs — that is where quotes honestly differ.

Can I replace my tank with tankless myself?

No — it involves gas work, venting and a permit, all of which require a licensed contractor in California. Badly vented gas appliances are a carbon monoxide risk.
