Number B: Links for Steel as well as Plastic Pipe
FAMILY MEMBERS HANDYMAN
Numerous homes have actually galvanized steel or plastic (CPVC) water supply pipelines. Galvanized steel pipelines are difficult to change. We recommend that you eliminate the pipelines back to the nearby tee, screw on a plastic-lined galvanized nipple and finish the connections with copper as shown in our photo series.
As a result of prospective heat accumulation, maintain plastic pipeline a minimum of 6 in. away from the air vent as well as storage tank. Make a change from plastic to copper with an unique combining that’s offered anywhere CPVC is sold.
Adaptable copper adapters are less complicated to set up than strong copper, especially when the existing pipelines as well as the storage tank inlets don’t align. Yet not all neighborhood codes enable them. If yours does, take unique care not to pinch or kink them. You could get a leakage.

Shut down the gas and also water
Shut off the gas to the hot water heater by transforming the nearby shutoff valve a quarter turn. When off, the take care of need to go to an appropriate angle to the pipe. Shut off the main water system also and also drain pipes the lines by opening up a faucet on the lowest floor.
Drain the water in the tank
Connect a yard hose pipe to the drain valve and also drain pipes the water left in the tank. Caution: The water will certainly be scalding hot! Separate the gas line at the close-by union with a pair of wrenches and also unscrew the pipeline from the gas control shutoff with a pipe wrench.
Cut off the water lines
Loosen the vent pipe from the air vent hood and also relocate sideways. After that reduce the cold and hot water lines with a tube cutter. (Unscrew unions for galvanized pipe or the nuts on versatile adapters if you have them.) Slide the old hot water heater out of the way.
Attach the safety valve
Wrap the strings of the brand-new temperature level as well as pressure relief valve with Teflon tape (three turns). Screw it snugly into the storage tank with a pipe wrench. Connect a copper discharge pipeline (see Fig. A for directing information).
Affix pipeline settings up
Solder brand-new copper adapters to 6-in. lengths of 3/4-in. copper and screw the settings up right into the warm water electrical outlet as well as cold water inlet ports in the top of the storage tank. Add short, plastic lined nipple areas to secure against galvanic rust, especially if you have hard water or if they’re needed by local codes.
Connect the water lines
Glide the brand-new water heater into place, recut or prolong the old tubing to fulfill the new, and solder the tubes with each other using copper slip couplings. If the tubes does not line up, counter the lines as required with sets of 45-degree elbows.
Reattach the air vent
Reconnect the air vent. Shove it snugly over the draft hood and also anchor it with three 3/8-in. No. 6 sheet metal screws. Predrill the openings. The vent need to climb a minimum of 12 in. vertically before turning at the very first elbow.
Use two wrenches to attach the gas line
Reconnect the gas line. Coat the threaded ends with pipeline joint substance and screw the initial nipple area into the gas shutoff. Usage 2 monkey wrench to avoid stressing the shutoff. Rebuild the remaining nipples, ending up with the union (Photo 2). Then comply with these 4 actions to fill the container: (1) Close the drain valve; (2) turn the water back on at the major shutoff and also open up the chilly water valve to the hot water heater (leave it open); (3) turn on a close-by warm water tap until water appears; and also (4) inspect all the joints and also fittings for water leakages.
Look for backdrafting
Many water heaters rely on an all-natural draft to draw combustion fumes up the flue. If the draft doesn’t work, those fumes, potentially consisting of deadly carbon monoxide, will certainly splash out right into your home. After finishing your installment, check the draft.
Close all outside windows and doors and also activate your kitchen and bathroom exhaust fans. Then open up a close-by hot water tap up until you hear the burner in the hot water heater stir up. After a minute, relocate a cigarette smoking suit around the side of the draft hood (Image 7) in addition to the heating unit. The smoke ought to be created the vent pipeline. If the smoke does not attract, the fumes from the burner aren’t airing vent. Switch off the gas to the hot water heater and call an accredited plumber to fix the issue.
Check for leakages
Try to find bubbles at connections
Activate the gas and also inspect links for leaks by brushing a 50-50 mix of dishwashing fluid and water over the joints. If the blend bubbles, you have a leakage. Tighten up or reconnect joints that leak. Clean the joints completely dry when ended up. Call the plumbing examiner to check over your job. Follow the how-to recommendations that goes along with the pictures to see to it the connections are limited.
Light the pilot burner
Make use of a lighter to light the pilot light
Light the pilot burner according to the maker’s directions. (For electrical water heaters, transform the power on at the major panel after the electrical assessor checks your job.) Finally, set the temperature level to 120 degrees F., adhering to the installation directions. Light the pilot light in the new hot water heater as well as adjust the temperature level setup.

Setup Information for Electric Water Heaters
First turn off the power to the water heater at your main electrical panel. After that comply with the very same draining pipes treatments when it comes to a gas water heater.
When the water heater is drained, detach the electrical cables from the screw terminals under the gain access to panel, which is typically situated near the top. (If you do not have electric experience, work with an electrical contractor to handle all the electric circuitry.)
Comply with the producer’s guidelines for electrical wiring the new water heater. If the new water heater is much shorter and the old cords won’t reach, surface-mount a 4-in. x 4-in. x 1-1/2 in. steel electrical box on the wall surface or ceiling close by, run the old cords to package, and then run a new area of armored cable television or electric avenue to the water heater. Examine the directions and also make certain the ranking of the old fuse or circuit breaker is high enough to take care of the new water heater. Additionally, the circuit ought to have a shutoff switch within view of the water heater.
Call your neighborhood electrical assessor prior to you begin the task. You’ll possibly need a permit. Then, when you’re completed, have the electric assessor inspect your job.
Aluminum circuitry calls for special delivery. If you have aluminum electrical wiring, call a licensed pro who’s accredited to work with it. This electrical wiring is boring grey, not the boring orange that’s particular of copper.
How to Throw away a Hot Water Heater
Jeff Gorton, an editor at The Household Handyman, will show you exactly how to remove and throw away a water heater in our video tutorial. He will additionally reveal you the simple means to lug a water heater out of your house, also if you are functioning alone.
These suggestions will certainly make your work go quicker and easier:
Measure the height of your old hot water heater and also get a brand-new one the very same height so you don’t need to transform the length of the water, gas or electrical lines.
The drain shutoff (Photo 2) on old hot water heater frequently clogs up. If the water drains slowly, be patient. CAUTION: It’s scalding warm! SUGGESTION: Transform your hot water heater off 2 hours beforehand to permit the water to cool.
Hot water heater weigh regarding 150 lbs. You’ll require a strong assistant or a dolly when you relocate the old one out and wheel the brand-new one in. Rubbish solutions usually charge concerning $25 to take the old one. Innovative Plumbing & Drain
Before you begin, purchase the tools and also materials revealed here at a pipes supply or hardware store or a residence center. Inspect the dimensions of the supply of water pipes (most will certainly be 3/4 in. like the ones in our pictures) and buy the right-size fittings. With whatever available, you’ll need four to 6 hrs to finish the task (presuming no big drawbacks!).
The temperature level as well as stress relief valve is a safety and security tool that restricts container stress and also keeps it from taking off (Photo 4). A brand-new one need to be consisted of with every installment. For the shutoff to work effectively, the discharge pipeline must be kept free of blockages (Fig. A).
In regions with very mineralized water, or where needed by neighborhood codes, make use of 3/4-in. plastic-lined nipple areas (concerning $2 each; Photo 5 and Fig. A) for joining different metals, usually copper tubing to the steel tank. This slows corrosion.
When connecting the water lines, solder the copper fittings before you screw them to the tank so you do not heat up the tank itself while soldering (Image 5).
Use “slip” couplings to attach the old and new lines (Picture 6). Unlike routine combinings, they do not have an inner quit. You can move them on, straighten the copper tubing, after that glide them back and also focus them over the joint.
The brand-new inlets as well as outlets on the container do not always associate the old supply lines. Solder in a pair of 45-degree fittings to counter each line if required. Also change the old shutoff valve with a brand-new ball shutoff while you go to it (Picture 6). Vent sizes are sized according to the warmth output of the hot water heater. You might have to boost or decrease the vent dimension to make sure the most effective draft. CAUTION: If you’re unclear if your chimney has a liner, ask your pipes inspector. Innovative Plumbing & & Drain
Make gas connections with strong steel pipe (Picture 8) or soft copper with flare fittings (Fig. A). Both are more trustworthy and less expensive than adaptable stainless-steel adapters, which are not always permitted. Usage stiff copper instead of versatile copper water supply lines for the exact same reasons.
If you find your water heater substitute where leak might cause damages to the floor or other components of your home, established a pan of an authorized size under it (metal for gas water heaters). The pan must have a drainpipe tube that results in a house drain or various other approved location (outdoors where allowed). The temperature and also pressure safety valve discharge tube likewise need to bring about a drainpipe if leak would damage the floorings. If directing is hard, go over choices with your regional pipes assessor.
If you live in an earthquake-prone area, band the hot water heater to the wall surface with special straps (Fig. A; readily available at pipes stores and home centers). Your pipes examiner will inform you if they’re required.
Set the brand-new water temperature readying to no greater than 120 degrees F. to avoid hot.
