Sump Overload After Renovation Fixes
A French drain overloads a sump after renovation when new downspouts, regrading, or hardscape send more surface and roof water into the drain than the sump was sized to handle.
Symptom Guides · landscaping
Old French Drain Clogged With Sediment
A French drain in an older home clogs with sediment because fine silt migrates into the gravel and perforated pipe over time, especially in drains built without filter fabric. Flushing the pipe often restores partial flow, but a fully packed line usually needs replacement.
Symptom Guides · landscaping
French Drain Backs Up in Heavy Rain
A French drain outlet blocks during heavy rain because silt, leaves, roots, or debris pack the discharge end (the daylight point or pop-up emitter), so water backs up faster than the choked outlet can release it.

Generator Overload Shutdown in Winter
A whole-house generator hits winter overload shutdown when heating loads (furnace, well pump, space heaters) and their startup surges exceed the unit's output. Fix it by shedding non-essential circuits, adding a load management module, or repairing a weak capacitor or governor.

Attic Fan Not Pulling Air in Summer
Your attic exhaust fan isn't pulling air because of a failed thermostat that won't trigger the fan, a stalled or slow motor from a bad capacitor, a broken belt on belt-drive units, or blocked soffit intake vents that starve the fan of makeup air.
Symptom Guides · hvac
Attic Fan Running, Humidity Still High?
Your attic humidity stays high because the exhaust fan can't pull fresh air in (blocked soffit vents), the humidistat is set too high or failed, or moisture is entering the attic from bathroom fans, roof leaks, or the crawlspace below.
Symptom Guides · hvac
Attic Fan Wiring Suddenly Overheating?
Attic exhaust fan wiring overheats when a connection loosens, the wire is undersized for the motor's draw, or a failing motor pulls excess current. Shut the circuit off at the breaker and inspect before running it again.

Well Faucets Sputtering Air?
Intermittent sputtering faucets on a well system are caused by air in the water lines, most often from a waterlogged pressure tank, a well water level dropping below the pump intake, or an air leak on the suction side of the pump.
Symptom Guides · plumbing
Well Pump Pressure Getting Worse?
Worsening well pump water pressure is most often caused by a waterlogged pressure tank, a clogged pump intake, or a drifting pressure switch, and the fix ranges from a free air-charge adjustment to a pump replacement.

Sediment in Older Home Well Water
Sediment in an older home's well water is usually caused by a dropping water table, a worn well screen, a pump set too deep near the well bottom, or corroding galvanized pipe. A settling jar test tells you whether the source is the well or the plumbing.

Upstairs Pressure Loss: Bladder Tank
Your pressure tank's bladder has probably failed, so it can't hold an air cushion. Upstairs fixtures lose pressure first because height eats psi, and the collapsed pressure range starves them.
Symptom Guides · plumbing
Pressure Tank Leak at a Downstairs Fitting
Your pressure tank is leaking at a downstairs fitting because a threaded joint has loosened or corroded, usually on the tank tee where the gauge, switch, and drain connect. Downstairs fittings carry the highest system pressure, so they fail first.

Doorbell Dead in Winter? Here's Why
Your doorbell chime stops working in winter usually because a weak transformer finally fails or the exterior button corrodes and shorts from freeze-thaw moisture. Test the transformer for 16 to 24 volts AC, then check the button.
Symptom Guides · electrical
Doorbell Transformer Buzzing in Summer
Your doorbell transformer buzzes louder in summer because heat expands the metal laminations inside the coil, worsening normal 60Hz AC hum. A stuck doorbell button or an aging, overheating transformer are the common culprits.
Symptom Guides · electrical
Video Doorbell Low Power Fix
Your video doorbell shows low power because the doorbell transformer can't deliver enough voltage or wattage. Most need 16-24V AC and 10 VA or more, while older transformers only put out 8-10V at 5 VA.

Radiant Floor: Sudden Cold Zones
Sudden cold zones on radiant floor heat are usually caused by trapped air in a heating loop, a stuck zone valve, or a failing circulator pump that stopped moving warm water through that section.
Symptom Guides · hvac
Radiant Pump Won't Circulate Steady
A radiant floor pump that runs intermittently is usually air-locked, cycling on thermal overload, or losing power from a loose connection or failing capacitor. Bleed the loops, check the wiring, and listen for a hum without spin before replacing the circulator.
Symptom Guides · hvac
Radiant Floor Heat Keeps Overshooting
Your radiant floor heat overshoots because the slab keeps releasing stored heat after the thermostat stops calling, and a stat without floor sensing or proper cycle tuning can't compensate. It worsens as sensor calibration drifts or settings shift.
Symptom Guides · hvac
Radiant Manifold Leak in an Older Home
Your radiant floor manifold is leaking because an aging O-ring, corroded fitting, or loose compression connection has failed. In homes over 15 years old, brittle rubber seals are the most common cause.

Bay Window Center Pane Foggy in Winter
Your bay window's center pane fogs in winter because warm indoor moisture hits cold glass (surface condensation you can wipe off) or the sealed double-pane unit has lost its seal (fog trapped between panes you can't wipe off).
Symptom Guides · windows
Bay Window Seat Board Rot in Summer
Your bay window seat board rots in summer because warm humid air condenses on the cooler glass and drips onto the flat wood shelf, which holds moisture long enough to break down the board, especially if drainage or ventilation under the seat is blocked.
