Plumbing answers for Campbellsville, Kentucky homes.

TC’s Plumbing & Service posted in May 2025 that most residential water heaters can be replaced for under $1,000, including all the materials and an inspection. Prices for tanks and parts change, so call 270-299-1414 for today’s figure on your heater.

What moves the price is the size and type of tank, whether it is electric or gas, how hard it is to reach, and whether the old installation has to be brought up to the current Kentucky Plumbing Code. A like-for-like electric tank in a basement or utility closet is the simplest case.

Yes. Kentucky requires a plumbing permit and an inspection for every water heater replacement, including a like-for-like swap in a house.

The permit comes from the Division of Plumbing in the Kentucky Department of Housing, Buildings and Construction, and a state plumbing inspector assigned to the county checks the work. A licensed plumber takes out the permit as part of the job. A homeowner can take out a homeowner permit for work on their own primary residence, but not for a rental.

A tank water heater usually lasts 8 to 12 years. Hard, limestone-fed water tends to push that toward the short end unless the tank is flushed.

The date of manufacture is on the rating label, often worked into the serial number. If the tank is past ten years and showing rust at the bottom, damp insulation or rusty hot water, plan the replacement before it lets go on its own schedule.

That noise is sediment. Minerals settle on the bottom of the tank, water gets trapped underneath, and it pops as it boils up through the layer.

It is common in limestone country. The sediment makes the heater work harder and, on an electric tank, buries the lower element until it burns out. Flushing helps if it is done regularly from the start. On an old tank that has never been flushed, ask a plumber first, because the drain valve can clog or fail to close.

Once a year is a good habit here, starting when the heater is new.

Flushing drains a few gallons from the valve at the bottom of the tank to carry sediment out. Turn the power off at the breaker on an electric heater before draining it, because an element that runs dry burns out in seconds. If the heater is gas, or old and never flushed, have a plumber do it.

It is a thermal expansion tank. It gives heated water somewhere to go as it expands.

When a home has a check valve, a backflow preventer or a pressure-reducing valve on its water line, the plumbing is a closed system. Without an expansion tank, pressure climbs every time the heater fires and the relief valve drips. The plumbing code calls for expansion control on closed systems, so many replacements now include one.

That pipe comes from the temperature and pressure relief valve, the heater’s main safety device. A drip means the valve is opening or wearing out, and it should be looked at soon.

Never cap or plug that pipe, whatever the reason. If the valve is discharging a lot of hot water, turn off the power at the breaker (or set a gas heater’s control to off), close the cold water valve above the heater and call a plumber.

It can be, but it is not automatically the better choice. A tankless heater costs more to put in and needs regular descaling in hard water.

Gas tankless units need a larger gas line and proper venting. Whole-house electric tankless units need a great deal of electrical capacity, often more than an older farmhouse panel has. For many homes here a good tank heater, flushed yearly, is the sensible answer. A plumber can tell you which way your house leans.

Keep the heat on, let a thin stream run from the taps farthest from where the water comes in, and open the cabinet doors under sinks on outside walls.

Before winter, take hoses off the outside faucets, close the crawl-space vents and insulate any pipe you can reach in the crawl space, garage or well house. If you leave home during a cold spell, leave the heat at 55°F or higher. The nights that do the damage here are the ones that fall into the single digits with wind.

Open the tap it feeds, and find your main water shut-off before anything thaws. A frozen pipe often does not leak until the ice melts.

Warm the pipe gently with a hair dryer or a heating pad, working from the tap back toward the frozen spot. Never use a torch, a heat gun or any open flame: it starts house fires and can burst the pipe with steam. If you cannot find the frozen section, or it is inside a wall or under the floor, shut the water off and call a plumber.

In most homes around Campbellsville it is where the water line comes into the house: in the basement or crawl space on the wall facing the road, or in a utility closet near the water heater.

There is also a shut-off at the water meter, in a box in the ground near the road. On a well, switch off the pump breaker and close the valve at the pressure tank. Find yours today and make sure it turns. In an emergency, closing it is the first thing to do.

Yes. In cold weather, closing the foundation vents keeps freezing wind off the water lines under the floor.

Also check that the crawl-space door fits and that pipe insulation has not fallen away. Open the vents again in spring unless your crawl space has been sealed and conditioned on purpose.

It might be. Turn off every tap and appliance and look at the water meter: if the dial is still moving, a pipe is leaking.

If the meter is still, the water is more likely groundwater or rain running under the house, which is common here on clay and limestone after a wet spell. Either way it should not be left. Standing water rots floor framing and draws termites, and a leaking drain line under the floor is a health problem.

Shut the water off at the main, drain the lines, and deal with the water heater and the traps. Turning the heat down is not enough.

A proper winterizing shuts off and drains the water heater (power off first), opens every tap, drains or blows out the supply lines, and puts non-toxic RV antifreeze in the toilet bowls and drain traps. Homes around Green River Lake that are closed for the winter are the ones that flood in the first thaw. A plumber can do it in one visit and turn it all back on in spring.

It froze and split. A frost-proof faucet that had a hose left on it over winter holds water in the barrel, and the barrel cracks.

The crack is inside the wall, so it only leaks when the faucet is running. Stop using it until it is replaced, and take hoses off every fall.

Yes, as a rule. This is limestone country, and water that has touched limestone carries dissolved calcium and magnesium.

You see it as white crust on faucets and shower heads, spots on dishes and sediment in the water heater. Your water utility’s annual water quality report, or a simple hardness test, will tell you how hard your own supply is. Well and spring water in karst ground is often harder than the public supply.

Campbellsville Municipal Water treats surface water and supplies the city, and its system draws on Green River Lake. Outside the city, rural water districts and associations carry treated water along the county roads.

By 2008 about 99 percent of Taylor County households were on public water, according to the Kentucky Geological Survey. If you are not sure who supplies you, the name is on your water bill.

If scale is building up on fixtures and your water heater is filling with sediment, a softener will help. It is a matter of comfort and of protecting the plumbing, not of safety.

Have the water tested first so the softener is sized to the hardness and the household. Softeners discharge salty water when they regenerate, so on a septic system it is worth asking how and where it will drain.

That is called short cycling, and the usual cause is a pressure tank that has lost its air charge or has a failed bladder.

It can also be a leak somewhere on the system or a bad pressure switch. Short cycling wears a pump out quickly, so have it looked at soon. Switch the pump off at the breaker if it is cycling every few seconds.

It can be, but it should be tested. In karst ground, surface water reaches the groundwater quickly through sinkholes and cracks, so wells and springs are easily contaminated.

Have a private well or cistern tested for bacteria at least once a year and after any flood. Your county health department can tell you how to get a sample tested. A cistern also needs its roof, gutters and screens kept clean. Treatment such as an ultraviolet light or a chlorinator can be plumbed in where it is needed.

If it is low at one tap, the aerator or cartridge is probably clogged with grit. If it is low through the whole house, look at the main valve, the pressure regulator, old galvanized pipe or a hidden leak.

Galvanized steel water lines, common in houses built before the 1960s, rust shut from the inside until only a trickle gets through. On a well, low pressure usually points to the pressure tank or switch.

One slow fixture is a clogged drain. Every fixture slow at once, gurgling toilets, or sewage at the lowest drain points to the main line or the septic tank.

Wet, green or smelly ground over the tank or the leach field means the septic system itself is in trouble. A plumber clears and repairs the line from the house. Pumping the tank is done by a licensed septic pumper.

Every three to five years for most households, according to the U.S. Environmental Protection Agency.

A small tank, a big family or a garbage disposal shortens that. Keep the pumping receipts, because they are the first thing a buyer’s inspector asks for.

The local health department. In Kentucky an on-site sewage permit and a site evaluation from the county health department are required before a septic system is installed or altered, and a certified installer must do the work.

The plumbing inside the house and the line out to the tank fall under the state plumbing code and the state plumbing inspector. The tank and the leach field belong to the health department.

Grease, wipes of any kind (including the ones marked flushable), paper towels, feminine products, paint, solvents and large doses of bleach or drain cleaner.

A septic tank works because of the bacteria living in it. Spread laundry loads through the week instead of doing them all on one day, and fix running toilets promptly, because constant water can flood the leach field.

We do not recommend them. They rarely clear a real clog, they can damage old pipe, and they leave caustic water sitting in the drain for whoever opens it next.

A plunger or a hand snake is safer for a simple clog. If a drain clogs again and again, the pipe has a problem that chemicals will not fix.

Gurgling means the drain is short of air, usually from a partly blocked line or vent. A sewer smell usually means a trap has dried out or a vent or seal has failed.

Pour water into floor drains and little-used sinks and tubs to refill their traps. If the smell stays, or more than one drain gurgles, have it checked: sewer gas should not be in the house.

Ask for the plumber’s name and license number and look it up with the Kentucky Department of Housing, Buildings and Construction (DHBC), which licenses plumbers through its Division of Plumbing.

Kentucky issues two plumbing licenses: master plumber and journeyman plumber. A master plumber is the one who can take out permits and run a plumbing business, and a journeyman works under a master. A reputable company will give you its license details without fuss.

A journeyman plumber is licensed to install plumbing while working for a master plumber. A master plumber is licensed to contract for the work and take out the plumbing permits.

Both licenses are earned by documented experience and a state examination, and both must be renewed with continuing education.

Yes. Kentucky has a statewide plumbing code, and state plumbing inspectors assigned to each county inspect permitted work.

New plumbing, water heater replacements, sewer and water service lines and most alterations need a permit. An inspection protects the homeowner: someone with no stake in the job confirms it was done to code.

Ask who holds the master plumber license, whether the company is insured, whether the job needs a permit and who takes it out, and what the price includes.

Ask too whether you will hear the price before work starts and who will actually be in your home. Recommendations from neighbors carry weight in a town this size, so read what local customers have written.

Water you cannot stop, sewage coming up into the house, no water at all, or a water heater that is leaking or blowing off its relief valve.

Close the main water valve first for anything involving water under pressure. A dripping tap or a slow drain can wait for a normal appointment. If you are unsure, call 270-299-1414 and describe it.

Leave the building straight away and call your gas utility or 911 from outside. Do not go looking for the leak.

Do not switch lights or appliances on or off, do not use a phone inside, and do not light anything. On propane, close the valve at the tank if you can reach it safely from outside, and call your propane supplier. Gas piping is work for a licensed professional, never a do-it-yourself repair.

Yes. Kentucky law requires a call to 811 before you dig, so that buried utility lines can be marked.

The service is free. It marks public utilities, not private lines such as the water line from your meter to the house, a line to a barn or a septic line, so a plumber may still need to locate those.

TC’s describes itself publicly as “a qualified, insured, and experienced team.”

You are welcome to ask for proof of insurance and for the company’s Kentucky plumbing license details when you call 270-299-1414.
