Here’s a question worth asking in Arlington: if your water heater started leaking right now, where would the water go? For too many Arlington homeowners the honest answer is ‘across the garage floor,’ ‘into the hallway carpet,’ or — worst of all — ‘through the bedroom ceiling.’ East Arlington’s 76018 ZIP sits between the entertainment-district buzz and quiet ranch-home streets where water heaters have been quietly aging in garages for decades. A drain pan doesn’t prevent leaks; it controls them, catching the water and carrying it outside through a dedicated drain line while an alarm alerts you. It’s a simple installation that changes the entire consequence of a leak.

What a Proper Pan Installation Includes in Arlington
Plumbing codes require a drain pan under a water heater where a leak could cause damage — which, in practice, means attics, upper floors, finished spaces, and anywhere above living areas. But ‘required’ and ‘present’ are two different things in Arlington: we routinely find attic heaters with no pan, pans with no drain line, and drain lines that terminate inside the attic — which is like installing a smoke detector with no battery. Most homes in 76018 are 1960s through early-1980s brick ranch houses on concrete slabs, with the water heater tucked into the garage or a small utility closet. Many are long-held family homes and rentals, and it is common to find original-era plumbing that has been patched in places rather than replaced wholesale. Garages here pull double duty as laundry rooms and storage, so a weeping water heater can go unnoticed behind boxes for months.
A proper installation has four parts. First, the pan itself: sized at least 2 inches larger in diameter than the tank (for a standard 50-gallon unit, that means a 24- to 26-inch pan), made of corrosion-resistant material — we use heavy-gauge aluminum or high-quality polymer, never the thin pans that rust through in five years. Second, the drain line: minimum 3/4-inch pipe, sloped continuously downward, routed to an approved termination outside the home — never into a wall cavity, never just ‘near’ a floor drain. Third, elevation: the pan must sit level so water actually reaches the drain outlet. Fourth, and most overlooked: a leak alarm or automatic shutoff sensor in the pan, so you know about the leak while it’s still a drip.
In Arlington, the details matter more than average. Arlington’s municipal water runs moderately hard, and decades of mineral exposure take their toll on tank linings and anode rods. Homes of this era often still carry galvanized-steel piping segments or older copper with corroded dielectric unions at the heater connections. Slab foundations mean a leak that escapes the heater area can travel under flooring and surface in a bedroom or hallway far from the source. With so many 76018 water heaters pushing 15 to 25 years of service, the question is rarely whether sediment has built up — it is how much. We routinely drain tanks here that have several inches of hardened mineral sitting on the bottom. And for heaters in tight closets, we plan the pan around the reality of the space — including how a future replacement unit will be lifted in and out without destroying the pan, a detail installers who’ve never had to do a change-out routinely miss.
Does Your Arlington Water Heater Need a Pan (or a Better One)?
Start with the obvious: look under your water heater. No pan at all is the most common finding in Arlington’s 1960s–1980s brick ranch homes — especially garage installs from decades when nobody thought about it. Next most common: a pan is present but rusted through, which we see constantly on older steel pans in humid garages. A rusted pan isn’t a pan; it’s a decoration. Tap it — if it flexes, flakes, or has visible holes, it needs replacement.
Then check the drain. A pan with no drain line is just a shallow bathtub waiting to overflow — and in Arlington we find them everywhere, particularly under attic units where running the drain line was ‘too much trouble’ for the original installer. Follow the drain line if there is one: does it actually exit the building? We’ve traced pan drains that end inside wall cavities, drip onto garage floors, and terminate six inches above attic insulation. Most homes in 76018 are 1960s through early-1980s brick ranch houses on concrete slabs, with the water heater tucked into the garage or a small utility closet. Many are long-held family homes and rentals, and it is common to find original-era plumbing that has been patched in places rather than replaced wholesale. Garages here pull double duty as laundry rooms and storage, so a weeping water heater can go unnoticed behind boxes for months.
Finally, consider the location risk honestly. A garage heater with no pan risks the garage and whatever’s stored in it. A utility-closet heater shares walls with living space — a leak there means drywall, baseboards, and flooring. An attic heater with no pan is the nightmare scenario: 40 to 50 gallons draining through your ceiling. In Arlington, where slab foundations let heater-area leaks travel under flooring and surface rooms away, the pan isn’t optional equipment — it’s the difference between a service call and an insurance claim.
Our Pan Installation Process, Step by Step
Every pan installation in Arlington starts with an assessment: we look at the heater’s location, the space around it, where a drain line can realistically run, and — critically — the heater’s age and condition. If your tank is 14 years old and rusting, we’ll say so honestly: installing a pan under a dying tank is fine, but you should know a replacement is coming. If the heater is healthy, we proceed. Call (833) 713-2101 and we can usually assess and install within a day or two.
On installation day, we shut down the heater — power off for electric, gas to pilot or off for gas units — and drain enough water to lighten the tank for lifting. (Full drain-down isn’t always necessary, but we never lift a full 50-gallon tank; that’s 400-plus pounds of water.) We disconnect the supply lines as needed, lift the unit with proper equipment, set the new pan level, and reset the heater into it. Then we reconnect everything, run the new drain line with proper slope to an exterior termination, install the leak alarm sensor, refill and purge air, relight or re-energize, and test every connection.
Before we leave, we test the whole assembly: we pour water into the pan to verify it drains freely to the outside — not just ‘theoretically.’ We trigger the leak alarm so you hear what it sounds like. And we walk you through what to do if you ever hear it: which valve to close, and our number — (833) 713-2101 — to call next. The whole job typically takes two to three hours for a garage or closet install; attic installs with long drain runs can take longer.
