Let’s sort this out together
There's a small brass valve on the side of your water heater with a pipe running down toward the floor, and most homeowners never give it a second thought — until it starts dripping. Then the questions start: is this dangerous? Can I just tighten it? (Please don't cap it — we'll explain why.) That valve is the temperature and pressure relief valve, the tank's built-in safety release, and when it weeps, it's either worn out or trying to tell you something about pressure inside the tank. We sort out which one it is, replace the valve with one rated correctly for your unit, and make sure the underlying pressure is healthy. Call (833) 713-2101 and we'll take a careful look — Certified Professional, Licensed & Insured Team.
About this service
First, some neighborly context on what this valve actually does. Your water heater is a sealed steel tank full of very hot water under pressure. The T&P valve is designed to open around 210°F or 150 psi — letting off steam, literally — if temperature or pressure climbs too high. It's the reason a water heater is a household appliance instead of a hazard. So when it drips, we take it seriously, and you should too.
The visit itself is methodical. We check your home's water pressure (normal is around 40 to 60 psi; much above 80 is high), test the expansion tank if you have one, and look at whether the thermostat is behaving. If the pressure is normal and the valve still weeps, the valve has simply worn out — they do, after years of heat cycles. We install a new valve with the correct temperature and pressure ratings for your specific tank, route the discharge pipe properly, and verify everything under operating conditions. And we'll say it again because it matters: never cap, plug, or restrict that discharge pipe. If yours has been capped by a previous owner, tell us — that's the first thing we'll fix.
How it works
Water and energy don't mix, so the first move is always the same: the water supply to the heater gets shut off, and the gas or the breaker gets switched off too. Only then do we start looking closely.
Water travels, so the puddle isn't always under the leak. We check the top fittings, the T&P valve, the drain valve, and the tank shell itself — and we sort true leaks from plain winter condensation, which fools a lot of folks.
Before any wrench turns, you get the full picture in everyday language: what failed, what the fix involves, and — just as important — when a repair isn't the smart move and a replacement is.
Failed valves, fittings, and components get replaced with parts rated for your unit, connections get resealed properly, and the work area gets left tidy. No shortcuts, no mystery parts.
Water and power or gas go back on, every connection gets checked under pressure, the T&P valve gets verified, and we make sure hot water is flowing the way it should before we leave.
FAQ
Usually one of two things: the valve's internal spring and seal have worn out after years of service, or the valve is doing exactly what it was built to do — releasing water because temperature or pressure in the tank is running too high. That second case often traces back to a failed expansion tank or a thermostat that's letting the water get too hot. We test to find out which one you're dealing with, because the fix is different.
No — please don't. Capping the T&P valve or its discharge pipe removes the tank's protection against excessive pressure, which is a genuine safety hazard. The drip is a symptom; the right move is diagnosing the cause and fixing that, whether it's the valve itself or the pressure behind it.
With a gauge and a little detective work. We measure your home's static water pressure, check the expansion tank's air charge and bladder, and look at how the system behaves as it heats. If pressure is in the normal range and the valve still drips, the valve is the problem. If pressure is elevated, we fix the root cause first — a new valve alone won't solve that.

The spigot-like valve at the bottom of the tank takes a beating over the years, and the old plastic ones are famous for cracking or refusing to seal. We swap failed drain valves for sturdy brass ones that shut tight — and make your next tank flush a whole lot easier.
Years of heating and cooling work the top fittings loose, and where copper meets steel, corrosion quietly sets in. We reseat or replace weeping connections, renew dielectric unions, and replace tired flex lines — then check every joint under pressure before we call it done.
Tankless units are a different animal: no tank to rust through, but their own roster of leak points — condensate lines, isolation valves, heat-exchanger seals. We know where to look, and we get them sealed up and running right again.
A simple pan under the tank with a drain line to carry water away is the simplest peace of mind an older water heater can have. We fit properly sized pans for tanks in basements, closets, and finished spaces, so a slow leak stays a footnote instead of a flooring project.
Gas units deserve extra respect: water leaks and fuel systems in the same cabinet. We shut the gas down before touching a wrench, fix the water-side problem, then check the burner, venting, and connections before the unit goes back into service.
Electric tanks leak from their own special weak spots — heating-element gaskets and thermostat covers that can weep for months before anyone notices. Power comes off at the breaker first, every time; then we replace what's failed and confirm both elements are heating properly.
That small tank hanging near your water heater is the shock absorber for your whole plumbing system. When its bladder gives out, pressure spikes and the T&P valve starts weeping — and folks blame the valve. We test the air charge, replace tired tanks, and match the new one to your home's water pressure.
The shutoff on your cold-water inlet is the valve you reach for in a panic — and old gate valves love to seize or only half-close. We replace them with quarter-turn ball valves that shut positively with one motion, so the next leak is a mop-up, not a flood.
For the mornings you walk downstairs to standing water: we focus on stopping the water first, making the unit safe, and then sorting out whether a repair or a replacement is the honest answer. If water is spreading right now, shut off the heater's water supply if you safely can, then call.
Sometimes the kindest thing you can do for an old tank is retire it. When the tank shell itself is compromised or repairs have become a habit, we install a correctly sized new unit — new connections, proper venting on gas models, expansion tank checked — and we'll tell you straight when replacement beats another repair.
