Hot Water and Gas
Water Heaters and Gas Lines
These two go together more than people think. A gas water heater depends on a properly sized gas line, and a new gas appliance can change what your whole system needs. Because we’re a heating, cooling and plumbing company, the same team understands the water side, the gas side and the venting.
Water Heater Repair and Replacement
No hot water, water that runs out fast, rumbling from the tank, rusty water or a puddle at the base. We find the cause and tell you straight whether it’s a repair or a replacement. A leak from the tank body means replacement. A worn part, like a thermocouple, valve or anode rod, is usually worth fixing.
When you replace, we size the new tank to your household and give you more than one option at more than one price point. We also flush tanks and check anode rods, which is the cheapest way we know to help a water heater last.
Gas Line Installation and Repair
Adding a gas range, a fireplace, an outdoor grill or a new furnace? We run new lines, extend existing ones and repair old piping. Every line gets sized for the total load of the appliances on it and pressure tested before it goes into service, as the National Fuel Gas Code (NFPA 54) requires. If you’re replacing your heating system at the same time, we handle the gas side as part of furnace installation in Traverse City.
Find It Early
Leak Detection
A hidden leak doesn’t announce itself. It shows up as a stain on the ceiling, a soft spot in the floor or a water bill that doesn’t make sense.
How much water can one small leak really waste?
More than you’d guess. According to the U.S. Environmental Protection Agency, leaks in an average home can waste nearly 10,000 gallons of water a year. On city water, you pay for that on your bill. On a private well, you pay for it in pump wear, because the pump keeps kicking on to replace water that’s going nowhere.
Signs you might have a leak:
Our approach is to start with the simple checks and narrow it down from there, so we find the source with as little disruption to your home as possible. Then we explain what we found and what it takes to fix it.
Private Wells and Hard Water
Well Pumps and Water Softeners
Well Pump Service
Plenty of homes outside Traverse City run on private wells. According to Michigan’s Department of Environment, Great Lakes, and Energy (EGLE), Michigan has more household wells than any other state. When the pump has a problem, the whole house feels it.
We work on well pumps and the parts around them. Call us if you notice:
- No water, or water that comes and goes
- Low or uneven water pressure
- Sputtering faucets or air in the lines
- A pump that turns on and off far more than it used to
- Higher electric bills from a pump that runs too long
A submersible pump sits down inside the well itself, sometimes 100 feet or more below the surface, so diagnosing it properly matters before anyone pulls it. We check the pressure tank and the controls first, because a problem up top can look a lot like a failing pump down below.
Water Softener Installation
Hard water is common in Northern Michigan, and well water in this area can carry iron too. You’ll see it as white scale on faucets, spots on dishes, stains in sinks and soap that never seems to lather.
Hard water is also rough on your water heater. Minerals settle out as the water heats and build a sediment layer in the bottom of the tank. A water softener protects the tank, your fixtures and the pipes in between. We’ll talk through what your water needs and install a system that fits your home.
Our opinion? If you’re on a well with hard water and you’re putting in a new water heater, put in a softener too. It’s the easiest way we know to protect that new tank.
Summer Homes
Seasonal Winterization and Spring Turn-On
This is a big one up here. Summer homes and cottages around Grand Traverse Bay, on the inland lakes and up into Leelanau County, sit empty for months while the temperature drops well below freezing. Water left in the pipes freezes, expands and splits them.
Our summer home winterization service gets the water out of the system before the first hard freeze. We shut down and drain the plumbing, take care of the water heater and protect the system so it comes through the winter intact.
Then in spring, we handle the turn-on. We bring the water back, check for any damage from the winter, restart the water heater and make sure everything runs the way it should before you arrive for the season.
Planning to close up a cottage this fall?
Book early. Everyone wants it done in the same few weeks, and the calendar fills faster than you’d think.
Our Process
How We Work on Every Plumbing Job
Our process is the same no matter what we’re there for. We listen first, find the real cause, explain it in plain words and give you clear options and prices before any work starts. No surprise invoices.
In our experience, homeowners make better decisions when they understand the problem, and they don’t need a sales pitch to get there. It’s the same way we run our heating and cooling work.
We serve homes in Traverse City and across Leelanau County, Benzie County and Kalkaska County. If you’re already on our HVAC maintenance plans or you book heating maintenance this fall, ask us to check your water heater on the same visit. You can see everything else we do on our HVAC and plumbing services page, or get in touch through our contact page.
