Where leaks show up in Mount Pleasant
Where the unit sits decides how urgent a leak is, and in Mount Pleasant that is not uniform. Crawlspace and utility room through the older core, garage in the newer building. Access is the variable that moves the price here more than anything else, and we quote it before the visit rather than after we are under the house.
That matters more than the leak itself. Water escaping from a unit in a garage is an inconvenience. The same leak from an attic or an upper-floor closet is a ceiling, and it is the one case where we would rather you shut the cold inlet and call than wait for the morning rate.
- From the tank body: the unit is finished. A perforated shell cannot be patched, and anyone who says otherwise is selling you a delay.
- From the relief valve discharge: usually pressure rather than a failed valve. Put a gauge on a hose bib before replacing anything.
- From a fitting or connector: genuinely repairable, and frequently a $150 to $300 job rather than a replacement.
- Pooling with no obvious source: often condensate or the pan drain rather than the heater, which is worth establishing before anyone quotes you a tank.

What Mount Pleasant itself changes
The housing in Mount Pleasant
Mount Pleasant is a small town with a genuinely old core, listed as a historic district, wrapped in newer building on the edges. The older properties are the ones that surprise people: heaters tucked into spaces that were never designed for them, discharge pipes that were run to suit the room rather than the code, and shutoff valves that have not been turned in twenty years. We plan for that rather than discovering it.
The pipe era
The older core is where galvanised supply may still be in service. That shows up as weak flow on hot and cold together, which is a different fault from the hot-only restriction a heat trap nipple causes, and it is worth separating before anyone quotes you for a heater.
