TPR Valve Replacement
The T&P valve is the tank’s pressure whistle — it opens near 210°F or 150 psi. When it weeps, we determine whether the valve has worn out or the system pressure is genuinely high, then install a correctly rated replacement.

Emergency Quick Call
Every tank water heater will weep someday — a valve seal, a fitting, the slow beginning of the end. A leak pan is the humble answer: a tray under the tank with a drain line that carries that first water away before it reaches floors, drywall, and stored belongings. Our leak pan installation in Medford, MA sizes the pan to the tank and routes the drain line properly, so the protection actually protects. Call (833) 713-2101.

About this service
The cruelest leaks are the slow ones — a fitting that beads for weeks before anyone looks behind the tank, a drain valve that drips into a dark corner. By the time the puddle is visible, the subfloor has been drinking for a month. A pan changes the geometry of that story: water lands in the tray, the drain line carries it to a floor drain or exterior, and what would have been hidden damage becomes a visible trickle in a drain — or a leak alarm’s moment to sing, if you add one.
Installation is straightforward but fussy in the details: the pan must be wider than the tank’s footprint, the drain line needs continuous fall to its termination, and in tight closets the heater may need to be lifted and set into the pan. We handle the full job — pan, line, and placement — for tanks in garages, closets, attics, and finished spaces across Medford, MA. Call (833) 713-2101.

How it works
We look at where the tank sits, where a drain line can terminate with proper fall, and whether the space allows a pan under the footprint.
The pan must extend beyond the tank’s full footprint — a pan that the tank overhangs is decoration, not protection.
The heater is lifted and set squarely into the pan, with the T&P discharge pipe still terminating correctly above it.
Piping from the pan’s outlet to a floor drain or exterior termination, with continuous downward pitch — water will not climb to escape.
We pour water into the pan and watch it leave through the line, confirming the whole route before we call it done.
FAQ
No — a pan does not prevent leaks, it contains their consequences. The tank will still need its repair. What the pan does is buy time: slow leaks get carried to a drain instead of soaking into floors while nobody is looking.
Anywhere a leak would be destructive or hidden: finished basements, upstairs closets, attics, and anywhere the heater sits over living space. In an unfinished garage with a floor drain nearby the stakes are lower — but the pan still helps.
It is a natural pairing. The pan manages the water; the alarm announces it. A small sensor in the pan can alert you to a weeping fitting weeks before you would otherwise notice — and early notice is what turns a repair into a non-event.

When the tank shell has corroded or cracked, no component repair restores it. We install a correctly sized unit, evaluate the expansion tank, and test the full installation.
