Checklists you can print and fill in
Worksheets for each stage of owning a tankless unit. Check whether your house is ready, log every flush, map your shutoffs, and compare quotes line by line before you sign.
- Tankless water heater flushing log
Keep a simple record of every flush and filter cleaning. Over a few years the log shows how fast scale builds in your unit and whether your flushing interval is right for Fullerton's water.
- Error code and symptom log
Intermittent tankless problems are hard to diagnose from memory. Logging each code and symptom as it happens gives a plumber the pattern they need.
- Shutoff map for a tankless water heater
In a leak or a gas scare, you do not want to be hunting for valves. Mark each shutoff on this map now and keep it where everyone in the house can find it.
- Tankless installation quote comparison worksheet
Put each plumber's written quote into the same grid. Gaps and assumptions show up quickly when every quote is answering the same questions.
- Plumber hiring checklist for tankless jobs
Tick these off in order, from the first contact to the final walkthrough. It keeps the hiring process consistent no matter which licensed plumber you are considering.
- Yearly maintenance calendar for a tankless water heater
Spread small checks across the year so nothing piles up. Adjust the flushing month to match your manufacturer's interval and your own flushing log.
- No hot water: call now or wait?
Not every tankless problem is an emergency, but some are. Use this guide to sort what you are seeing into leave now, act today, or schedule a visit.
