Plumbing & Drains
18 articles · A–Z master index
Drain Systems
- How Traps and Vents Work in Drain Systems — The two-part system that keeps sewer gas out and drains flowing: how P-traps seal, why vents exist, siphoning and its signs, and the illegal traps inspectors still find.
- Main Sewer Line Problems: Roots, Bellies, and Collapses — The failure modes of the buried sewer lateral: root invasion, sags, offset joints, and collapse, the symptoms that point past the house, and the camera-first repair economics.
- Sewer Gas Smell in the House: Finding the Source — The sewer smell suspect list in order of likelihood: dry traps, failed wax rings, sink overflows, vent problems, and the rarer cracked pipe, with the test for each.
- Slow Drains: Diagnosis Before You Reach for Chemicals — The slow drain decision tree: one fixture versus many, the vent question, mechanical clearing that works, and why chemical openers sit last on the list.
- Sump Pumps: Types, Testing, and Maintenance — Pedestal versus submersible sump pumps, the five-minute quarterly test, check valves and discharge rules, battery backup strategy, and the failure signs before the flood.
Fixtures
- Leaking Faucet Repair: Cartridge, Ball, and Compression Types — Identify which of the four faucet mechanisms you own, match the drip to the worn part, and rebuild it: washers, cartridges, ball kits, and ceramic disc seals.
- Shower Diverter and Mixing Valve Problems — Why showers dribble from the spout, run lukewarm, or lose pressure: diverter types, cartridge and pressure-balancing valve failures, scald-limit stops, and the fixes.
- Toilet Keeps Running: Fill Valve and Flapper Diagnosis — The three-part machine inside every toilet tank, the food-coloring test that names the failing part, and the ten-minute repairs for flappers, fill valves, and chains.
Supply Systems
- Backflow Prevention: What Homeowners Should Know — How contaminated water can flow backward into drinking supply, the air gaps and vacuum breakers already protecting your house, irrigation backflow devices, and the annual test some systems require.
- Copper vs. PEX vs. CPVC: Residential Piping Compared — The three modern supply piping materials compared on lifespan, freeze behavior, water chemistry sensitivity, cost, and DIY-friendliness, with the honest weaknesses of each.
- Diagnosing Low Water Pressure in a House — A systematic low water pressure diagnosis: one fixture versus whole house, hot versus cold, sudden versus gradual, with the pressure regulator, filters, and pipe corrosion as the usual suspects.
- Dielectric Unions and Galvanic Corrosion in Plumbing — Why copper touching steel eats the steel, where galvanic corrosion strikes in houses, how dielectric unions and brass buffers break the circuit, and the water heater connection everyone forgets.
- Frozen Pipes: Prevention and Safe Thawing — Which pipes freeze and why, the prevention hierarchy from insulation to dripping taps, how to thaw a frozen line without starting a fire, and what to do the moment one bursts.
- Galvanized Pipe in Older Homes: Risks and Replacement — How galvanized steel supply pipe fails from the inside out, the symptoms by decade, the lead question, partial versus full repipe strategy, and what replacement involves.
- How to Find Your Main Water Shutoff Valve — Where main water shutoff valves hide by region and house type, gate versus ball valves, the curb stop, and why exercising the valve annually matters more than knowing the address.
- How to Read Your Water Meter and Detect Hidden Leaks — The water meter as a leak detector: reading dials and digital displays, the leak indicator triangle, the shutoff isolation test that localizes the leak, and what the usual suspects are.
- Washing Machine Hoses: The Overlooked Flood Risk — Why washer supply hoses are a leading cause of home water damage, rubber versus braided stainless, the five-year replacement rule, and the shutoff habits that cap the risk.
- Water Hammer: Causes and How Arrestors Fix It — Why pipes bang when valves close, the physics of hydraulic shock, the difference between hammer and other pipe noises, and the fixes from arrestors to pressure control.
