Use this page as an index. Each answer below is a summary — the linked page gives the checks, the reasoning, and the next step in full. If water is spreading, start with our emergency page rather than browsing FAQs.
Diagnosis questions
How do I find where my heater is leaking? Work top to bottom: fittings, TPR valve, drain valve, element covers, then base and seam. Full order on our diagnosis hub.
Is a top leak serious? Usually repairable, but worth addressing promptly — a top leak can run down the tank and look like a bottom leak. See top leaks.
Is a bottom leak always tank failure? Not until a trail from above is ruled out. Once confirmed at the base or seam, replacement is the usual direction. See bottom leaks and bottom seam leaks.
Could it be condensation? Possibly, if the wetness is cool, broad, and humidity-linked. The checks are on our condensation page.
Could it be a slab leak instead? If the heater stays dry but the floor stays wet, or water continues with the heater supply off, the source is elsewhere. See heater versus slab.
Repair, replacement, and parts questions
Repair or replace? Location first, age second, home type third. The framework is on our repair-versus-replacement page, and the job itself is on our replacement page.
What drives replacement scope? Unit type and size, home type, access, connections, platform condition, and the permit check. Factors, not figures, on our cost factors page.
What does a TPR drip mean? Intermittent discharge often relates to expansion; steady discharge needs attention sooner. Never cap the discharge pipe. See TPR valve and expansion tank.
What about drain valve, element gasket, and gas control leaks? Each has its own page: drain valve leaking, drain valve replacement, element gasket, and gas control valve.
What do anode rods and sediment have to do with leaks? The anode rod protects the tank from corrosion, and sediment affects heating and tank life. Both are checked on a visit, and both are covered on our anode rod page and sediment page.
Gas, electric, and home-type questions
Do you work on gas and electric heaters? Yes. Gas patterns are on our gas page, and electric patterns on our electric page.
Do you work on manufactured and park-model homes? Yes. Park-model replacements follow the City rule: equivalent type and size, same or less demand, no exterior installation, and a permit plus an approved detached accessory structure for a larger unit.
What are the early warning signs? Rust staining, intermittent dampness, lukewarm or discoloured hot water, and popping noises. Full list on our warning signs page.
Emergency and contact questions
What do I do first in an emergency? Move items off the floor, shut the water off only if you can do so safely, and call us. Full triage on our emergency page.
How do I schedule service? Contact us to schedule your service at (480) 555-0147. Tell us where the water first appears, how fast it is spreading, whether it is hot, and whether the home is site-built, manufactured, or a park model.
Frequently asked questions
Where is my water heater leak coming from?
Work top to bottom: top fittings, TPR valve, drain valve, element covers, then base and seam. Our diagnosis hub gives the full order and a leak-location guide.
Should I repair or replace my leaking water heater?
Repair fits a part or connection leak on a sound tank. Replacement fits a tank body or seam leak, or a heater whose condition makes another repair a short-term fix. See our repair-versus-replacement page for the framework.
Is a TPR valve drip an emergency?
Intermittent discharge often relates to expansion, while steady discharge needs attention sooner. Never cap or block the discharge pipe, and call us if discharge is steady or the valve will not reseat.
Do you provide services for manufactured and park-model homes?
Yes. Park-model replacements follow the City rule on equivalent type and size, same or less demand, no exterior installation, and a permit plus an approved detached accessory structure for a larger unit.
What should I do if water is spreading from my heater?
Move items off the floor, shut the water off only if you can do so safely, and call us. Do not use gas or electrical controls if the floor is wet around them.
