All modern plumbing systems in residential construction have a plumbing vent. It doesn’t just vent unwanted odors from the drainage system to the outside; it actually serves an important purpose by supplying air to the system.
The plumbing drainage system in your home is actually called a drainage, waste and vent (DWV) system. When water flows down the piping, an air supply (vent) is needed to allow the water to flow. Think of the vertical pipe as a drinking straw. If you plug the top end of a straw, liquid won’t drain from it.
The DWV system in your home consists of a series of pipes connected to each fixture; they extend above each fixture, and the system terminates at an open pipe that extends through the roof. This piping allows air into the system and prevents unbalanced pressures in the piping.
The vent also prevents the system from drawing water out of a trap at the fixture with the characteristic “glug-glug-glug” as the drain gasps for air. Plumbing traps should drain smoothly and never “glug” or gasp for air.
If your home has a drain that empties slowly or gurgles as it drains, this may indicate a venting problem. If you flush a toilet and the sink gurgles, there’s definitely a vent problem. Have a plumber check this.

Most bathroom sinks have a “pop-up” sink stopper that opens and closes when you operate a small knob or lever built into the faucet. Push it down and the stopper pops up to drain the sink; lift it up and the stopper closes.
Most of these mechanisms need adjustments from time to time, and many are never set just right in the first place. Take a look at the illustration. The rod at the rear of the sink will allow adjustment where the metal strap with holes attaches to the stopper rod. The rod can be placed in holes at different heights to raise or lower the mechanism. The perforated rod also allows a sliding adjustment where it is attached to the solid rod that goes up through the sink.
If the sink is plugged, place a bucket below the sink, then loosen the nut and pull back the rod for the pop-up stopper at the tail piece of the sink drain. (A little water may leak out.) This will disconnect the pop-up stopper, and you can remove it to clear out debris that always collects here.

If your home has natural gas or propane appliances, you should know where the gas valves are located and how to turn them off.
All gas appliances are required to have a special valve located on the pipe near the appliance. Look at your gas cooking range – you should see a valve just behind the unit where the flexible connector connects to the pipe. Also, there should be a valve on the side of a gas furnace or gas water heater.
The illustration shows a typical gas valve that is operated with a small wrench. The valve may have a larger handle you can operate with your hand, and in some newer installations there may be a valve with a large handle. In essence they all work the same: when the handle is parallel to the pipe, the gas is on; when perpendicular to the pipe, the gas is off.
Make sure the valves are off and the pipe is capped if your home has a gas supply line with no appliance connected to it. If you ever smell gas in your home, leave immediately. Call for help from outside your home – you can call the local gas utility or the fire department.

OK, for many years compact fluorescent lamps (CFL) were a bit of a pain. They provided an eerie color, took a long time to reach full brightness, never worked outdoors in cold weather, and failed early.
Most of those problems have been solved in the last 20 years. Now it’s hard to resist these lamps, which provide the same amount of light as incandescent lamps for about 25 percent of the energy cost. They also generate about 75 percent less heat inside an air-conditioned space, which is important in areas where air conditioning is used often.
They are color-corrected to provide a natural color. When you purchase the lamps, look for the “warm white” or “natural” color notation on the packaging. The color-corrected CFLs really do have great color. They’re available as spotlights and floodlights, and there are special versions for circuits with light dimmers. The bulbs are small enough to fit in most household lamps and fixtures.
If you do the energy calculation, you’ll see there is a great payback for substituting CFLs over incandescent bulbs. They also last about six to 12 times longer than incandescents.

So you run the bath exhaust fan to remove moisture – but then you get that drip, drip, drip from the fan on your nice clean rug. Bath exhaust fans should not drip. If yours does, there’s something wrong with it.
First, check the exhaust ducting or tubing; it should be insulated, straight and vented to the outside. There should be a minimum of bends for proper air flow. If there is no insulation around the duct, the problem could be condensation in the cold duct. Adding insulation around the duct may solve the problem.
The fan’s damper can also get stuck in the open position, allowing hot air into the cool duct and creating condensation. Check the small damper at the fan. It should open when the fan is on and close when the fan turns off. This damper responds to fan pressure and gravity. Most vent connectors through the roof or sidewall should also have a damper to keep cold air out, and it should open and close with fan operation.
For many years, contractors installed bath fan vent ducting incorrectly, creating a bend or low loop to catch condensation. This just allows water to accumulate and may cause a large leak when the water lets go.

When a rain gutter and downspout send their discharge below grade to a pipe, it may appear that rainwater is draining into a sanitary sewer, but it really isn’t. In municipal areas with sewer systems, gutter (rainwater) discharge is normally routed into a storm sewer. This storm piping routes water to rivers and streams and is separate from the sanitary sewer system.
Municipal systems include a sanitary sewer system that routes toilet, shower and sink water to a sewage treatment plant. The flow of storm and sanitary sewer systems would never be combined unless a really old system is in place or there are problems with the system. In the old days before good sewage treatment, homes had combined sewers – but that is not common today.
When you live out in the country, your gutters may discharge below grade and be directed underground to the side of a hill or a lower spot. Rural areas don’t have storm sewers.
Here is a tip. Look at the curb and gutter in front of your house. If you see grates there, rainwater flows into a storm sewer system below the street.

You may not know what a GFCI is, but chances are it’s making your home safer. A ground fault circuit interrupter (GFCI) measures current flowing through a circuit. It looks simple, but it’s really a complex electronic device.
Electricity flows like water through a circuit. The GFCI measures this flow; if the device is operating properly, the flow into and out of the device should be the same. If the GFCI detects a slight leak of current (perhaps through your body), it immediately disconnects the circuit. That’s where the term “ground fault” comes from – the GFCI detects that the current is “grounding” when it’s not supposed to.
What about a circuit breaker or fuse? Wouldn’t one of these detect an imbalance? Circuit breakers and fuses are designed to prevent wires and devices from overheating. A 15-amp breaker will allow 15 amps of power to flow before it trips the circuit. That 15 amps is enough to light more than 15 100-watt bulbs; it’s enough current to kill a person. In fact, just a fraction of an amp flowing through your heart could be fatal. A GFCI will trip before that happens.
Remember to use the test button to check the GFCI periodically. Plug a lamp into the circuit; the lamp should turn off when you push the test button, tripping the GFCI.

You should view extension cords as a necessary evil. Avoid using them. If you must use an extension cord, use a heavy duty cord with a sturdy plug and outlet. Make sure the cord is in good condition.
Some basic rules:
- Never run an extension cord through a doorway where it could get damaged.
- Never run an extension cord under a rug where it can’t be seen and could overheat.
- Never run a cord where it could present a trip hazard.
- Never use two extension cords end to end – you just double the risk.
- Never use a cord with exposed wires or a loose plug or outlet.
- Never cut or modify the cord or connectors.
For appliances like washing machines, toasters or hair dryers, don’t use an extension cord, period. Have an electrician install an outlet near the appliance so a cord is not needed. These appliances use lots of energy and can overheat an extension cord.
All permanently installed appliances – a garage door operator or sump pump, for example – must have an electrical outlet nearby so an extension cord is not needed.

All types of siding eventually accumulate dirt and grime, maybe even some mildew. It might make you think you need to paint the siding. But that’s not so. Often, it’s easy to wash dirt from the surface if the underlying finish is in good shape.
Some professionals use a pressure washer on siding, but that is really overkill. It can damage caulk and force water into the siding.
Try washing your siding with a mild detergent and water. You can wet the surface and then spray with the detergent/water mix in a garden sprayer. Use a soft brush – the kind you use for washing a car – and put the brush on a long pole to make the job easier. Work from the bottom up, and keep wetting the area below the part you’re scrubbing to prevent dirty wash water from streaking dry siding. Rinse with clear water.
If your siding has gray, black or green spots, try washing with JOMAX – a great product for removing mildew. Just follow label directions. You spray the product on the surface, wait and then rinse it off. For tougher dirt, you may need to scrub a little.
You will be surprised at how a little elbow grease and detergent can make your siding look like new.

Let’s say that every time you turn the small globe valve for the outdoor hose bib, you get that drip-drip-drip from the body of the valve. Or maybe your drip occurs at the small needle valve for the icemaker or the humidifier – turn the valve, and the darned thing leaks.
Maybe you wire a coffee can below the valve to catch drips, and the problem is solved – until the can overflows onto the floor.
It’s time to adjust the packing nut. What’s that? Most needle, globe and gate valves have a packing nut that surrounds the valve stem. On these valves you normally turn the handle around and around to control the flow. The valve handle is sealed at the stem with a packing nut and flexible packing below the nut.
The fix? Tighten the hex nut slightly to compress the packing around the valve stem, and the leak will stop. This may make the valve harder to turn, so don’t tighten it too much – just enough to stop the drip. If the drip continues, you may need to dismantle the valve and replace the packing, a job often best left to a plumber.
If you allow a valve to continue dripping, deposits will build up around the valve stem and eventually ruin the valve.
