Number B: Connections for Steel and also Plastic Pipeline
FAMILY MEMBERS HANDYMAN
Many residences have actually galvanized steel or plastic (CPVC) water system pipelines. Galvanized steel pipelines are tough to replace. We suggest that you eliminate the pipes back to the nearest tee, screw on a plastic-lined galvanized nipple area and also complete the connections with copper as displayed in our picture series.
Due to potential heat accumulation, keep plastic pipeline at least 6 in. far from the air vent and container. Make a shift from plastic to copper with an unique combining that’s available anywhere CPVC is sold.
Versatile copper ports are much easier to set up than strong copper, especially when the existing pipelines and also the container inlets don’t line up. Yet not all neighborhood codes allow them. If yours does, take special treatment not to pinch or kink them. You can get a leakage.

Shut off the gas as well as water
Shut off the gas to the hot water heater by turning the close-by shutoff valve a quarter turn. When off, the handle should be at an ideal angle to the pipeline. Shut off the main supply of water too as well as drain the lines by opening a tap on the lowest flooring.
Drain the water in the storage tank
Affix a yard tube to the drain shutoff as well as drain the water left in the container. Caution: The water will be scalding hot! Disconnect the gas line at the nearby union with a pair of wrenches and also loosen the pipe from the gas control valve with a pipe wrench.
Cut off the water lines
Loosen the air vent pipeline from the vent hood as well as relocate sideways. After that reduce the hot and cold water lines with a tube cutter. (Unscrew unions for galvanized pipe or the nuts on flexible connectors if you have them.) Glide the old hot water heater off the beaten track.
Attach the relief valve
Wrap the strings of the brand-new temperature level and also stress relief valve with Teflon tape (3 turns). Screw it tightly into the container with a pipe wrench. Attach a copper discharge pipe (see Fig. A for transmitting details).
Connect pipe assemblies
Solder new copper adapters to 6-in. sizes of 3/4-in. copper and screw the settings up into the hot water electrical outlet as well as cold water inlet ports in the top of the container. Add short, plastic lined nipple areas to secure against galvanic deterioration, especially if you have hard water or if they’re needed by local codes.
Affix the water lines
Glide the brand-new hot water heater right into area, recut or expand the old tubing to satisfy the new, and also solder the tubing with each other making use of copper slip couplings. If the tubes does not align, balance out the lines as required with sets of 45-degree elbows.
Reattach the vent
Reconnect the air vent. Shove it snugly over the draft hood and anchor it with 3 3/8-in. No. 6 sheet metal screws. Predrill the holes. The vent need to climb at least 12 in. up and down before turning at the first arm joint.
Use 2 wrenches to connect the gas line
Reconnect the gas line. Coat the threaded ends with pipeline joint compound and also screw the initial nipple area right into the gas valve. Usage two pipe wrenches to avoid worrying the valve. Reassemble the continuing to be nipples, ending up with the union (Picture 2). After that follow these four actions to fill up the container: (1) Shut the drain shutoff; (2) turn the water back on at the main shutoff and open the chilly water shutoff to the water heater (leave it open); (3) activate a nearby hot water tap till water appears; as well as (4) evaluate all the joints and installations for water leaks.
Look for backdrafting
A lot of hot water heater depend on an all-natural draft to attract combustion fumes up the flue. If the draft does not work, those fumes, possibly including dangerous carbon monoxide gas, will certainly spill out right into your house. After completing your setup, examine the draft.
Close all external doors and windows and also turn on your kitchen and bathroom exhaust fans. After that open up a close-by hot water faucet up until you hear the burner in the hot water heater ignite. After a minute, relocate a cigarette smoking match around the edge of the draft hood (Image 7) in addition to the heating system. The smoke must be created the vent pipeline. If the smoke doesn’t attract, the fumes from the burner aren’t venting. Switch off the gas to the hot water heater as well as call an accredited plumbing technician to correct the problem.
Check for leakages
Look for bubbles at links
Activate the gas and check links for leakages by cleaning a 50-50 combination of dishwashing liquid and also water over the joints. If the blend bubbles, you have a leak. Tighten or reconnect joints that leakage. Clean the joints completely dry when ended up. Call the pipes assessor to check out your work. Adhere to the how-to guidance that goes along with the photos to make certain the connections are tight.
Light the pilot light
Utilize a lighter to light the pilot burner
Light the pilot light according to the producer’s directions. (For electrical water heaters, turn the power on at the main panel after the electrical inspector checks your work.) Lastly, established the temperature to 120 degrees F., following the installment guidelines. Light the pilot burner in the new hot water heater and readjust the temperature setup.

Installation Details for Electric Water Heaters
First turn off the power to the water heater at your main electric panel. After that comply with the very same draining pipes treatments as for a gas hot water heater.
When the hot water heater is drained pipes, disconnect the electrical cords from the screw terminals under the access panel, which is normally situated near the top. (If you do not have electrical experience, employ an electrician to deal with all the electrical circuitry.)
Comply with the producer’s instructions for electrical wiring the new hot water heater. If the new hot water heater is much shorter as well as the old cables will not get to, surface-mount a 4-in. x 4-in. x 1-1/2 in. metal electric box on the wall surface or ceiling close by, run the old cables to package, and then run a new area of armored cable television or electrical conduit to the hot water heater. Examine the instructions and also see to it the score of the old fuse or breaker is high sufficient to deal with the brand-new hot water heater. Additionally, the circuit needs to have a shutoff switch within sight of the hot water heater.
Call your neighborhood electric inspector prior to you begin the work. You’ll possibly require a permit. Then, when you’re completed, have the electrical assessor check your job.
Light weight aluminum circuitry needs special handling. If you have light weight aluminum electrical wiring, call an accredited pro that’s licensed to deal with it. This electrical wiring is boring grey, not the boring orange that’s particular of copper.
Exactly how to Get rid of a Water Heater
Jeff Gorton, an editor at The Family Handyman, will reveal you just how to get rid of and also dispose of a hot water heater in our video clip tutorial. He will likewise show you the easy way to carry a water heater out of your residence, also if you are working alone.
These suggestions will certainly make your job go much faster as well as easier:
Determine the height of your old water heater and also buy a new one the same height so you do not need to transform the length of the water, gas or electrical lines.
The drain valve (Image 2) on old water heaters typically congests. If the water drains pipes slowly, hold your horses. CARE: It’s scalding hot! SUGGESTION: Transform your water heater off 2 hrs ahead of time to allow the water to cool down.
Hot water heater evaluate concerning 150 pounds. You’ll need a solid assistant or a dolly when you relocate the old one out as well as wheel the new one in. Trash solutions commonly charge about $25 to take the old one. Innovative Plumbing & Drain
Prior to you start, acquire the tools as well as products revealed right here at a plumbing supply or equipment shop or a home facility. Inspect the dimensions of the supply of water pipes (most will certainly be 3/4 in. like the ones in our pictures) and also acquire the right-size installations. With every little thing accessible, you’ll need 4 to 6 hours to finish the job (thinking no huge drawbacks!).
The temperature level as well as pressure safety valve is a safety and security device that limits container stress and also keeps it from blowing up (Picture 4). A brand-new one have to be included with every installment. For the shutoff to function appropriately, the discharge pipe have to be kept without blockages (Fig. A).
In areas with extremely mineralized water, or where called for by regional codes, use 3/4-in. plastic-lined nipple areas (concerning $2 each; Picture 5 and Fig. A) for joining various metals, normally copper tubes to the steel storage tank. This slows deterioration.
When linking the water lines, solder the copper fittings prior to you screw them to the storage tank so you do not heat up the container itself while soldering (Image 5).
Usage “slip” couplings to attach the old and brand-new lines (Photo 6). Unlike normal combinings, they do not have an interior stop. You can glide them on, line up the copper tubing, then move them back as well as center them over the joint.
The new inlets as well as outlets on the tank do not constantly line up with the old supply lines. Solder in a set of 45-degree fittings to offset each line if essential. Also replace the old shutoff valve with a brand-new round shutoff while you’re at it (Photo 6). Air vent diameters are sized according to the heat outcome of the water heater. You could need to raise or lower the air vent size to ensure the most effective draft. CARE: If you’re uncertain if your smokeshaft has a lining, ask your plumbing assessor. Cutting-edge Plumbing & & Drain
Make gas links with solid steel pipe (Picture 8) or soft copper with flare fittings (Fig. A). Both are a lot more reliable as well as less expensive than versatile stainless steel connectors, which are not constantly allowed. Use stiff copper rather than flexible copper water supply lines for the exact same reasons.
If you locate your water heater replacement where leak could trigger damages to the floor or other parts of your home, set a pan of an approved dimension under it (steel for gas water heaters). The pan should have a drain tube that causes a residence drainpipe or other approved area (outdoors where allowed). The temperature level and also pressure relief valve discharge tube additionally must bring about a drain if leak would certainly harm the floorings. If routing is hard, review alternatives with your neighborhood plumbing inspector.
If you reside in an earthquake-prone area, strap the water heater to the wall with unique bands (Fig. A; available at pipes stores as well as residence centers). Your plumbing inspector will tell you if they’re required.
Set the brand-new water temperature setting to no more than 120 degrees F. to prevent scalding.
