Water Heaters
Getting the old one out and the new one in is frequently harder than the plumbing, and it is the part that gets underestimated.
Repair or replace
A straightforward test that holds up most of the time: if a modest repair buys several more years of ordinary service, repair is the better financial decision. If the tank itself is leaking, replacement is the only answer, because a leaking tank is a failed tank and nothing brings it back.
| Repair | Heating element, thermostat, relief valve, a failed connector, a stuck mixing valve |
|---|---|
| Replace | Tank weeping or leaking, heavy internal corrosion, a unit near the end of its life needing a second repair |
Common complaints, and what they usually are
- Hot water runs out sooner than it used to. Sediment in the bottom of the tank taking up volume, or an element that has failed while a second one carries on.
- Water is hot then cold then hot. Often a mixing valve rather than the heater itself.
- Hot is weak but cold is fine. Scale in the hot run. A supply problem wearing a water heater costume. See water pressure.
- Rumbling or popping. Sediment. Flushing may help if it is caught early enough.
- Water around the base. Establish whether it is the tank or the relief valve discharging, because those are very different conversations.
The access problem
In a Chelsea walk-up or a loft with a service elevator that has a booked schedule, the route matters as much as the unit. A tank that fits the closet may not fit the stairs, the doorway, or the elevator. We work this out before ordering, not on the day of delivery, because a heater standing in a lobby helps nobody.
This is also where a narrower or shorter tank of the same capacity sometimes solves an otherwise impossible job, and occasionally where a tankless unit earns its keep purely on footprint.
Tankless
Endless hot water and a much smaller footprint, which in a Manhattan apartment is often the real attraction. In exchange it needs adequate electrical capacity, and flow rate governs how many fixtures can run at once. The honest version: it is an excellent answer where space is the binding constraint and the supply can carry it, and an expensive one where it is chosen for its own sake.
Building hot water plant
Where the building generates hot water centrally, one plant serves everybody and a fault is noticed by every tenant at the same time. Those jobs are about planning the shutdown as much as the repair. See commercial plumbing for how we handle work in occupied buildings.
Exercise the temperature and pressure relief valve once a year and drain a few gallons off the bottom of the tank. It takes ten minutes and it is the difference between a heater reaching its life expectancy and falling short of it.
