Number B: Connections for Steel and also Plastic Pipeline
FAMILY MEMBERS HANDYMAN
Many homes have galvanized steel or plastic (CPVC) supply of water pipes. Galvanized steel pipes are tough to replace. We suggest that you eliminate the pipelines back to the nearest tee, screw on a plastic-lined galvanized nipple and complete the connections with copper as shown in our photo collection.
As a result of potential heat buildup, keep plastic pipeline at least 6 in. away from the air vent and storage tank. Make a shift from plastic to copper with a special coupling that’s offered anywhere CPVC is marketed.
Versatile copper adapters are much easier to set up than solid copper, specifically when the existing pipes and the tank inlets do not align. However not all local codes enable them. If your own does, take special care not to pinch or kink them. You can get a leak.

Shut down the gas as well as water
Shut off the gas to the water heater by turning the nearby shutoff valve a quarter turn. When off, the handle ought to be at a right angle to the pipe. Turn off the main water system also and also drain pipes the lines by opening a tap on the lowest flooring.
Drain pipes the water in the storage tank
Affix a garden pipe to the drainpipe shutoff as well as drain pipes the water left in the container. Care: The water will be scalding warm! Separate the gas line at the neighboring union with a pair of wrenches as well as unscrew the pipeline from the gas control valve with a pipe wrench.
Cut off the water lines
Loosen the air vent pipe from the vent hood and move it sideways. Then reduce the hot and cold water lines with a tube cutter. (Unscrew unions for galvanized pipeline or the nuts on flexible adapters if you have them.) Glide the old water heater off the beaten track.
Connect the safety valve
Cover the threads of the new temperature and stress safety valve with Teflon tape (three turns). Screw it tightly into the container with a pipe wrench. Affix a copper discharge pipeline (see Fig. A for routing information).
Connect pipeline assemblies
Solder brand-new copper adapters to 6-in. lengths of 3/4-in. copper and also screw the settings up into the warm water outlet and also chilly water inlet ports in the top of the tank. Add short, plastic lined nipple areas to protect versus galvanic corrosion, especially if you have tough water or if they’re called for by neighborhood codes.
Attach the water lines
Slide the new water heater right into location, recut or expand the old tubing to meet the brand-new, and solder the tubing together making use of copper slip couplings. If the tubing does not align, offset the lines as needed with sets of 45-degree joints.
Reattach the vent
Reconnect the air vent. Shove it tightly over the draft hood and also anchor it with 3 3/8-in. No. 6 sheet metal screws. Predrill the openings. The vent should rise a minimum of 12 in. up and down prior to transforming at the very first elbow.
Use 2 wrenches to affix the gas line
Reconnect the gas line. Cover the threaded ends with pipeline joint substance and also screw the first nipple right into the gas shutoff. Use 2 monkey wrench to stay clear of emphasizing the shutoff. Reconstruct the continuing to be nipple areas, ending up with the union (Photo 2). After that adhere to these four steps to load the container: (1) Close the drain shutoff; (2) transform the water back on at the main shutoff and open up the cool water valve to the water heater (leave it open); (3) switch on a nearby hot water faucet until water appears; as well as (4) examine all the joints and installations for water leakages.
Look for backdrafting
Many water heaters depend on a natural draft to attract burning fumes up the flue. If the draft does not work, those fumes, perhaps consisting of lethal carbon monoxide, will certainly spill out into your home. After finishing your installment, inspect the draft.
Close all exterior windows and doors and switch on your kitchen and bathroom exhaust fans. After that open up a neighboring warm water tap until you hear the gas burner in the water heater fire up. After a minute, move a smoking suit around the edge of the draft hood (Picture 7) on top of the heating unit. The smoke ought to be formulated the air vent pipeline. If the smoke does not attract, the fumes from the burner aren’t venting. Switch off the gas to the hot water heater and also call a licensed plumbing technician to correct the issue.
Check for leaks
Look for bubbles at connections
Activate the gas as well as check connections for leaks by brushing a 50-50 blend of dishwashing liquid and water over the joints. If the mix bubbles, you have a leakage. Tighten up or reconnect joints that leak. Clean the joints dry when ended up. Call the plumbing inspector to check out your job. Comply with the how-to recommendations that accompanies the photos to see to it the connections are tight.
Light the pilot light
Make use of a lighter to light the pilot light
Light the pilot burner according to the maker’s directions. (For electrical water heaters, turn the power on at the major panel after the electrical examiner checks your job.) Lastly, established the temperature level to 120 levels F., complying with the setup instructions. Light the pilot light in the brand-new hot water heater and readjust the temperature setting.

Setup Information for Electric Water Heaters
First shut off the power to the water heater at your major electrical panel. Then follow the exact same draining pipes procedures when it comes to a gas water heater.
When the water heater is drained, disconnect the electrical cables from the screw terminals under the accessibility panel, which is usually found near the top. (If you don’t have electrical experience, work with an electrical expert to deal with all the electrical circuitry.)
Adhere to the supplier’s instructions for wiring the brand-new water heater. If the brand-new hot water heater is much shorter and the old wires won’t reach, surface-mount a 4-in. x 4-in. x 1-1/2 in. steel electric box on the wall or ceiling nearby, run the old cables to package, and after that run a new section of armored cord or electrical conduit to the hot water heater. Inspect the guidelines and make certain the score of the old fuse or breaker is high sufficient to deal with the new hot water heater. In addition, the circuit should have a shutoff switch within view of the hot water heater.
Call your regional electric inspector prior to you begin the job. You’ll probably require a license. After that, when you’re ended up, have the electrical assessor inspect your work.
Light weight aluminum circuitry requires special handling. If you have light weight aluminum wiring, call a qualified pro that’s licensed to deal with it. This circuitry is dull grey, not the dull orange that’s particular of copper.
Just how to Get rid of a Hot Water Heater
Jeff Gorton, an editor at The Family Handyman, will certainly show you exactly how to eliminate and also throw away a hot water heater in our video clip tutorial. He will certainly also show you the easy way to bring a hot water heater out of your home, even if you are functioning alone.
These suggestions will make your job go faster and also easier:
Measure the height of your old water heater as well as get a new one the exact same elevation so you don’t need to transform the length of the water, gas or electric lines.
The drain valve (Picture 2) on old water heaters commonly clogs up. If the water drains gradually, hold your horses. CARE: It’s scalding hot! POINTER: Transform your water heater off two hrs beforehand to allow the water to cool.
Water heaters consider regarding 150 lbs. You’ll need a strong helper or a dolly when you relocate the old one out and also wheel the brand-new one in. Trash solutions generally charge concerning $25 to take the old one. Innovative Plumbing & Drain
Before you start, get the devices as well as materials shown here at a plumbing supply or equipment shop or a house center. Inspect the sizes of the water system pipelines (most will be 3/4 in. like the ones in our pictures) as well as acquire the right-size fittings. With everything accessible, you’ll require 4 to six hrs to finish the job (assuming no large hitches!).
The temperature level and pressure safety valve is a safety and security device that limits container pressure as well as keeps it from taking off (Photo 4). A new one have to be consisted of with every installation. For the valve to work effectively, the discharge pipeline have to be maintained devoid of blockages (Fig. A).
In areas with very mineralized water, or where needed by neighborhood codes, use 3/4-in. plastic-lined nipple areas (about $2 each; Picture 5 and Fig. A) for signing up with various steels, usually copper tubing to the steel container. This slows down deterioration.
When attaching the water lines, solder the copper installations prior to you screw them to the storage tank so you don’t heat the storage tank itself while soldering (Picture 5).
Use “slip” combinings to connect the old as well as new lines (Image 6). Unlike regular couplings, they do not have an inner stop. You can move them on, align the copper tubes, then slide them back as well as focus them over the joint.
The brand-new inlets and also outlets on the storage tank don’t always associate the old supply lines. Solder in a pair of 45-degree fittings to offset each line if required. Also change the old shutoff valve with a brand-new round shutoff while you’re at it (Image 6). Air vent diameters are sized according to the warmth output of the water heater. You may need to enhance or reduce the vent dimension to make certain the best draft. CAUTION: If you’re uncertain if your smokeshaft has a liner, ask your plumbing assessor. Innovative Pipes & & Drain
Make gas connections with solid steel pipeline (Photo 8) or soft copper with flare installations (Fig. A). Both are much more reliable as well as less expensive than versatile stainless steel ports, which are not constantly permitted. Usage inflexible copper as opposed to versatile copper water lines for the exact same reasons.
If you find your water heater replacement where leak can cause damages to the flooring or various other components of your home, established a frying pan of an accepted size under it (steel for gas water heaters). The frying pan needs to have a drainpipe tube that causes a residence drainpipe or various other accepted location (outdoors where allowed). The temperature level as well as pressure relief valve discharge tube also must bring about a drain if leakage would certainly damage the floors. If routing is challenging, review options with your local plumbing assessor.
If you live in an earthquake-prone area, strap the water heater to the wall surface with unique bands (Fig. A; readily available at plumbing stores and also house centers). Your plumbing examiner will certainly tell you if they’re needed.
Establish the new water temperature level setting to no greater than 120 levels F. to prevent hot.
