A recent water heater repair & replacement call
A Washington customer in their 1990s home had been chasing tankless unit producing cold-water sandwich for weeks before calling. Calcium scale in the heat exchanger was the actual cause. We descaled the unit and recommended annual maintenance; everything stable since. About $856 all in.
What we cover
Water heaters last 8 to 12 years on average — less in hard-water regions, more if the anode rod gets replaced every 4 years. Most calls come at end-of-life when the tank starts leaking from the bottom seam.
When the tank goes, swap it. Repair on a 10-year-old tank that's leaking is throwing money away. We carry standard 40 and 50 gallon gas and electric tanks on our trucks for same-day install. Tankless replacements take 1–2 days because of the gas-line and venting work.
If you've a tankless unit and you're getting cold-water sandwich (hot for 30 seconds, cold for 10, hot again), it's almost always scale buildup in the heat exchanger. Annual descaling fixes it — $225 to $380 — and is required by the manufacturer to keep your warranty valid.
Brand-wise, we install whatever you want. Defaults we keep stocked: Rheem and AO Smith for tank, Rinnai and Navien for tankless. Bradford White on commercial.
