Most often a T&P relief valve discharging from high pressure or a bad seal. Inspect the valve, drain area, and all fittings to locate the source.
-
Bradford White Water Heater Water Too Hot - Causes & Fix
Usually a faulty temperature sensor or control misreading tank temperature. Measure actual tank temp and sensor resistance to isolate.
-
Bradford White Water Heater Not Enough Hot Water - Causes & Fix
Usually a thermostat set too low or a failed thermopile/gas valve on gas models. Raise the setting first, then test pilot output.
-
Bradford White Water Heater No Hot Water - Causes & Fix

Scale buildup on the heat exchanger causes trapped water to flash into steam and pop through mineral deposits. Flush and descale the unit.
-
Rinnai Water Heater Pilot Won't Stay Lit - Causes & Fix
Flame failure is usually a dirty flame rod or blocked vent. Clean the flame sensor and check venting for obstructions or improper install.
-
Rinnai Water Heater No Ignition - Causes & Fix
Low gas pressure or a closed gas valve is the most common cause. Open the gas valve fully and check inlet pressure at the valve.
-
Navien Water Heater Rusty Water - Causes & Fix
Rusty water usually means corrosion or sediment in the heat exchanger or supply plumbing. Flush the system and check for leaks.
-
Navien Water Heater Popping Noise - Causes & Fix
Popping usually means scale or sediment has built up on the heat exchanger. Flush and descale the unit to remove mineral deposits.
-
Navien Water Heater Pilot Won't Stay Lit - Causes & Fix
Navien units use electronic ignition, not standing pilots. A 'pilot won't stay lit' usually means ignition failure (Error 11 or 12) from a dirty flame rod or gas supply issue.
-
Rheem Water Heater Rusty Water - Causes & Fix
Rusty hot water usually means a depleted anode rod or internal tank corrosion. Replace the anode if possible, otherwise replace the unit.
-
Rheem Water Heater Making Popping Noise - Causes & Fix
Sediment buildup at the tank bottom is the most common cause. Flush the tank through the drain valve until water runs clear to resolve it.
-
