High country plumbing is a different discipline from valley plumbing. The building materials are the same, but the conditions are not: colder for longer, thinner air, properties that sit empty for weeks, water from a well rather than a main, waste into a tank rather than a sewer, and access that a February storm can simply cancel. Most serious mountain plumbing damage is a freeze that happened while nobody was there.
Vacancy is the real hazard
An occupied house is a monitored house. Taps run, warm air circulates, someone notices when the heat goes off. An empty one has none of that, so a tripped furnace, a power outage, an unplugged heat tape or a propane tank that ran dry becomes a burst pipe with hours of unattended water behind it. That is the pattern behind most of the expensive calls up here, and the reason the useful conversation happens in October rather than in January.
If you own a property you do not occupy full time, there are only two defensible strategies. Winterise it properly — water off, system drained, traps and appliances dealt with — or keep it heated with real redundancy: a reliable heat source, a remote temperature alarm you actually receive, and someone local who can physically get to the house when it alerts. Half measures, like leaving the thermostat at fifty and hoping, are how ceilings end up on floors.
Anyone renting a mountain property short-term inherits a third problem: guests who turn the heat down when they leave, open windows in winter, and put things down drains that a septic system cannot process.

Call About an Empty PropertyWells, septic and boilers
Three systems dominate mountain service calls. Wells, where the usual failures are a pressure tank that has lost its charge, a pressure switch, or a pump at the end of its life — and where the symptom for all of them is simply no water. Septic systems, which need pumping on a schedule and which announce trouble as slow drains everywhere at once, a green stripe over the field, or backups after a heavy-use weekend. And hydronic heat: boilers and radiant floors are far more common up here than in valley subdivisions, and they fail in ways forced-air homeowners find unfamiliar.
Heat tape deserves a category of its own. It is what keeps exposed lines and vulnerable runs above freezing in cold country, and it is routinely found unplugged, damaged by rodents, or simply dead after years of service. Knowing where yours runs, and testing it before the first hard freeze, is one of the highest-value ten minutes available to a mountain homeowner.
Appliance sized at valley elevation? That is a common and expensive mismatch up here.
Question the SizingWhat altitude does to appliances
Gas appliances lose output as air thins, and much of this region sits between eight and nine thousand feet. A water heater specified without accounting for that can run out of hot water in midwinter, when incoming water is coldest — and tankless units are the most sensitive of all, since their output depends on temperature rise across a flow rate. Venting, combustion air and derating are part of a correct installation up here, not optional refinements.
If you arrive to a frozen house
Close the main shutoff before you start thawing anything. A frozen line that has already split will release water the moment it thaws, and if the water is off you get a controlled repair instead of a flood. Then call, and say whether you have heard water running.

Shut the water off at the source, drain the system from the lowest point, open taps to break the vacuum, deal with the water heater and any appliance that holds water, and put antifreeze rated for plumbing in the traps and toilets. Do not use automotive antifreeze. Once it is done properly the house can sit at any temperature without freeze risk, which is a far better position than depending on a furnace all winter.
Usually, with patience and the right method — gentle even heat applied from the open end of the line toward the blockage, so meltwater has somewhere to go. Torches and rapid heat are how pipes split and how houses catch fire. If the pipe has already cracked, thawing simply reveals it, so the water should be off before anyone starts.
Roughly every three to five years for a full-time household, and it depends on tank size and how heavily the house is used. Vacation rentals often need it sooner than the owner expects because occupancy comes in bursts. Slow drains throughout the house rather than at one fixture is the classic sign that the tank rather than the plumbing is the problem.
Because the incoming water is much colder in January, so the same heater has to do considerably more work for the same shower. At altitude a gas unit also produces less than its sea-level rating. That combination is why heaters that seem fine for nine months fall short in the coldest ten weeks, and why sizing here needs to be done for winter conditions.
Shut the water off at the main and drain what you can from the lowest fixture, which stops the damage from growing. Move what matters out of the water path, take photographs for any claim, and get a temperature reading if you can. When you call, describe the access honestly — road conditions, plowing, gates, the last stretch of driveway — because that is what decides who can come and when.
The equipment is similar, the conditions are harder. Well houses and exposed pipe runs freeze, access for pulling a pump can be limited by snow, and depth to water varies more in fractured rock. The practical difference is that mountain well repairs are more weather-dependent to schedule, which makes replacing an aging pump before it fails more attractive than it would be elsewhere.
