Getting the installation right in Davidson
The permit is the part that varies most between towns, and getting it wrong is what turns a one-day job into three weeks. In Davidson it goes through Mecklenburg County alongside Town of Davidson planning. We pull it where the work needs one and we tell you plainly where it does not, rather than adding a fee for a permit nobody filed.
We size on first-hour rating rather than raw gallons, because that is what decides whether you run out. A 50 gallon gas unit and a 50 gallon electric unit are not the same appliance in practice.
- Expansion control charged to your measured pressure. Tanks ship pre-charged at 20 to 40 psi and this region routinely runs far higher. Fitted unchanged, it is waterlogged from day one.
- A discharge pipe that will pass inspection: full valve size, no valves or tees, no threads on the end, terminating within six inches of the floor.
- Pan and drain line wherever the unit sits above living space, which in Davidson is decided by where the heater actually is.
- Refill and purge before energising on electric units. Powering an element before the tank is full destroys it in under a minute.
What Davidson itself changes
Where the heaters sit
Utility room, closet and crawlspace in the older centre. Garage and attic in the newer subdivisions. Attic installs are the ones we want to know about on the phone, because a leak in an attic is a different urgency from a leak in a garage.
The pipe era
Mixed with the build years. The oldest properties near the campus may have galvanised in service; the newer stock is copper and PEX.
