I woke up one morning to a high pitched whistle emitting from my water heater and water leaking from it. When I called Guardian Plumbers, the dispatcher immediately put me at ease and quickly scheduled someone to come out and investigate that day. I really appreciate Matthew’s expertise, willingness to explain all water heater options and overall work ethic. I’m so thankful for all the support from the Guardian Plumbers team. Definitely recommend them!

A damp spot under the tank, a new whistle, or showers gone lukewarm call for a plumber who tells you what’s wrong and why. Guardian Plumbers, Heating, Air & Electrical repairs and replaces tank water heaters and tankless units throughout Canyon Lake.
We want to be someone you can trust in your home. That starts with hearing what you’ve noticed, then telling you honestly whether your water heater needs a repair or has reached the end of its life.
A worn thermostat, heating element, gas control, or relief valve can cause most of these, and so can sediment or a tank that’s simply worn out. We’ll test the unit and look it over as a whole, and if a simple repair will do the job, that’s what we’ll recommend.
If water is spreading, shut the cold-water valve above the tank if you can reach it safely, then switch off the breaker on an electric unit or turn the gas control to off on a gas unit.
If you smell gas near the water heater, leave the house without switching anything on or off, and once you’re outside, call SoCalGas at 1-800-427-2200.
“Guardian Plumbers responded quickly to my water heater problem. Jesse explained everything to me that was going to happen in a manner I could understand. He was polite, courteous and answered all my questions.” —Gordon B.
Have Your Water Heater Checked
Most Canyon Lake homes were built before 1990, and much of the community went up during the 1980s. In a house that age, the water heater has likely been replaced more than once, and the venting, gas line, and water connections around it may come from different decades, so we check them before quoting any replacement.
Replacement makes sense when the tank is leaking, the water runs rusty, or an older unit keeps needing repairs. If yours only needs a part, we’ll tell you that instead. We install gas and electric tank water heaters sized to how your household uses hot water, and financing is available if you qualify.
The City of Canyon Lake has a permit specifically for water heater replacement, and it comes with a city inspection. California law also requires the new water heater to be braced, anchored, or strapped against earthquakes.
On a replacement, we take care of:
A tankless water heater mounts on the wall and heats water only when a tap is open, so it isn’t keeping a full tank hot around the clock. Switching from a tank can require updates to the gas line, venting, or electrical.
We’re certified installers for Navien and Rinnai tankless units, and we’ll quote a new tank as well, so you can see both options before you choose.
Most Canyon Lake homes get their water from EVMWD, and its 2025 water quality report puts the average hardness in the range the USGS deems hard. In a tank, those minerals settle as sediment, which is often the rumbling or popping you hear, and in a tankless unit they build up as scale.

If necessary, remember to add GoAccess authorization for Guardian as a service provider before your appointment so your technician isn’t held up at the entrance. On restricted holidays such as the 4th of July and Labor Day, members can add service providers as temporary guests instead.
Many Canyon Lake houses are weekend or seasonal homes. When a house sits empty for weeks, a slow drip at the water heater can soak the garage floor before anyone notices. Before a long absence, it’s worth having the tank looked at, and some owners shut off the water supply to the house while they’re away.
A yearly visit can cover a tank flush, a check of the anode rod and relief valve, and descaling for a tankless unit. If something is starting to wear, we’ll show you.

Often it is, if the tank itself is sound and the problem is a part. If the tank is leaking or rusting, or an older unit needs repairs often, replacement tends to be the better value.
Yes, we handle it. We pull the city’s replacement permit, meet the inspector, and strap the new water heater the way California requires.
That depends on what failed, and you’ll get a clear price once the technician finds the cause. A noise or a leak can come from a single part or from the tank itself, and those are very different jobs. The work waits for your go-ahead.
Plan on periodic descaling. Minerals in the water build up inside the unit over time, and cleaning them out keeps it heating the way it should. We can service your unit and tell you how often it needs it.
Often, yes, and we’re open 7 days a week. Call (951) 678-3275 to ask about today.
