Tomball properties run the range from century-old homes near Main Street to acreage on private wells to subdivisions that finished construction last spring. Leaks look different in each of them. Molberg Plumbing handles leak detection and repair across all of it, from a failed supply connector in a new build to a well line that’s been losing water underground for months. We locate the source with proper equipment before recommending anything, so you’re not paying to open walls on a hunch.
Leaks get more expensive the longer they run. If your water bill climbed, your pressure dropped, or something smells damp, contact us and we’ll track it down.

The causes tend to repeat, and most of them come down to age, pressure, and ground movement:
We’ve also found leaks in shower pans, irrigation manifolds, and pressure tanks that looked fine from the outside. However yours started, locating it comes first.

Some leaks put water on the floor within minutes. Others run underground or behind tile for a year. Here are the failures our Tomball techs see most and what usually gives each one away.
Cracked supply tubes, loose P-trap joints, and corroded angle stops drip into cabinets where the damage stays hidden. The cabinet floor swells first, then the subfloor, and mold follows before the smell reaches you.
Water lines running beneath a concrete foundation corrode and split, saturating the soil underneath. Warm flooring, a meter that keeps moving with everything off, and a rising bill are the signs. We locate the break precisely instead of opening concrete to search.
Pipes inside framing can weep for months. Bubbling paint, yellow or brown staining, and drywall that gives under pressure are the symptoms. In older homes near downtown Tomball, pinhole corrosion in aging copper is a frequent cause.
A deteriorated wax ring releases water onto the subfloor at every flush, rotting the area around the flange. Inside the tank, a failing flapper wastes water continuously with nothing visible to see.
Exterior spigots crack at the stem or split below grade, releasing water directly into the soil against your foundation. Nothing drips where you’d notice, which is why these run so long.
Rust at the base, weeping at the pressure relief valve, or pooling under the unit means the tank is failing. Hard water shortens tank life around here, so keep an eye on anything approaching ten years old.
Cracked grout, failed pan liners, and worn valve seals let water pass into the subfloor and framing. The tile can look perfect while the structure beneath takes on water week after week.
Sprinkler laterals and service lines crack from soil movement and root pressure. Soggy ground, one section of grass outgrowing the rest, and summer bills that don’t match your watering schedule are the clues.
On well properties, leaks in the supply line, pitless adapter, or pressure tank connections cause the pump to short cycle and run up your electric bill. We diagnose the plumbing side and address the leak at its source.

Repairs usually happen on the spot. Bigger jobs get scheduled around you, and every job is backed by our workmanship warranty.

Once we know exactly where the leak is, we can talk about the smartest fix. Sometimes a single fitting solves it. A slab leak in a home that has already leaked twice may be better handled by rerouting the line than by repeating the same repair a third time. Long runs across acreage often benefit from replacement rather than patching. For failing drain and sewer lines, our trenchless methods restore the pipe without trenching through your yard. Every option comes with a real price attached.
A few practical habits cut your risk considerably. Have your water pressure tested and install a regulator if it’s running above the recommended range, because high pressure is behind a surprising share of failures. Keep grease and debris out of drains so lines aren’t working under strain. Swap out flexible appliance connectors every few years rather than waiting for one to burst.
With hard water common in Tomball, water treatment does real preventive work by slowing scale buildup inside your water heater and fixtures. Annual maintenance handles the rest, and our VIP Membership keeps it scheduled with priority service when something comes up.
Listen for the pump. If it cycles on when no water is being used, something in the system is losing pressure. That can be a leak in the supply line, the pitless adapter, a bad check valve, or a failing pressure tank, and we can narrow it down for you.
Not to find it. We use acoustic listening equipment and line tracing to pinpoint the location first, which keeps any excavation limited to the spot that needs it rather than a long exploratory trench.
Hard water. Mineral content builds scale on the tank bottom and eats through the anode rod faster, and once that protection is gone the tank itself starts corroding. Annual flushing and a softener both extend the life of the unit considerably.
Treat it as one. Water under the foundation saturates soil that moves with moisture, which leads to cracked tile, uneven floors, and foundation repair that costs far more than the plumbing. It also runs continuously, so the waste accumulates around the clock.
Yes. Long runs across a property are common in Tomball and they’re a frequent source of losses that never show up as a puddle. We trace the line, locate the break, and repair or replace the affected section.
Shut off the supply valve at the fixture if you can reach it, or close the main if the source isn’t clear. Move rugs and belongings out of the water, photograph the damage in case you file a claim, and hold off on running the dishwasher or washing machine.
It depends on your policy. Sudden failures are often covered while slow leaks that ran unnoticed frequently aren’t, and many policies cover the resulting damage without paying for the pipe repair. We provide written findings and photos to support your claim.
No. Estimates are free, you’ll have the price before work starts, and financing is available if the repair turns out larger than you planned for.
Water heaters, repipes and sewer lines don’t wait for a good month. Get the price on paper first, then pay it off over time.
