The tankless complaints we hear
These units tell you what hurts — sometimes with an actual code on the screen.
- An error code on the display. Every code points somewhere. Tell us the number when you call.
- Hot, then cold, then hot again. The classic complaint. Usually flow-related, and fixable.
- No hot water at all. Ignition, gas supply or venting. A systematic check finds it.
- Weak flow makes the water go cold. Low-flow cutoffs and clogged inlet filters do this.
- The unit keeps shutting itself off. Overheat protection doing its job — and asking for service.
- Years since the last flush. Around here, that alone explains a lot of tankless trouble.
Whatever it’s doing, odds are we cleared the same thing this month. Call (951) 574-3134 or send us a request.
The same family, for 25+ years
We Care Plumbing, Heating & Air is a family company — three generations in, still family operated, and still answering our own phones 24 hours a day. After 25+ years serving Southern California homes, we now run crews across Orange County every day.
Do one trade this long and you learn what actually fails. We know what hard water does to a water heater, what tree roots do to a sewer line, and what decades-old pipe does to water pressure — and Orange County’s mix of older neighborhoods and newer builds keeps all of it in play. That’s why maintenance isn’t an upsell for us — it’s the cheapest repair you’ll ever buy.
And pricing is simple: you approve a flat quote before any work begins, and you never pay more than you were quoted.
WHat You Can Count On
- Same day service
- Upfront pricing
- BBB A+ rated
- Family operated
- Financing available
- 10% military discount
- Free in-home estimates

Good to know
Why descaling matters here
Local water is hard, and scale collects inside a tankless heat exchanger the same way it does on a shower head — you just can’t see it happening. A yearly flush keeps the temperature steady and the unit alive. If yours has never been flushed, start there.

Common tankless questions
What does my error code mean?
Each brand’s codes map to specific faults — ignition, flow, venting, scale. Tell us the code when you book and the tech arrives ready for it.
Why does the water go hot, cold, then hot?
It’s common enough to have a nickname — the cold water sandwich. Usually flow-related, and one of the most routine things we fix.
How often should it be flushed?
Once a year in our water. Skipping it shows up as temperature swings, falling flow and a shorter life.
Do you work on my brand?
We service most major tankless brands. If it heats water on demand, odds are good.
Repair or replace?
Tankless units are built to be repaired, and a maintained one outlasts a tank by years. If yours is genuinely done, we’ll say so and price the replacement honestly.
