Getting Started Installing Your New Warm Water Storage Tank
We’re replacing a natural gas hot water heater in our presentation. The actions for replacing a gas hot water heater are precisely the same, and those for an electric hot water heater are comparable.
Regardless, when you’re planning a water heater replacement, play it safe. Call your local department of assessments and also ask if you require a permit. And make certain a plumbing or electric inspector checks your job.
Installation Costs and Labor
Plumbing technicians commonly bill $45 to $65 an hour as well as can usually set up a water heater in a day or in 6-8 hours.
Many residential water heaters set you back $150 to $400 for either gas or electrical, plus $200 to $450 if you have a plumbing mount it. A lot more expensive gas water heaters with unique venting systems also are available. However they’re more difficult to install, as well as we won’t take care of them below.

When to obtain a new water heater
Your water heater is dead when the storage tank leakages. The indicator that your water heater requires replacing is a slow drip below, typically appearing as a route of rusty water. This indicates that the steel tank has actually rusted via as well as can not be taken care of. Other signs, such as not enough or no hot water, normally signal various other hot water heater repair service problems that you can take care of.
If you detect a drip, strategy to change the water heater right now. Do not wait until the leak obtains negative.
New hot water heater include installation guidelines and also lots of cautions to make certain you manage the gas, electrical as well as other links securely. In this post, we’ll supplement those basics with techniques as well as “real world” suggestions from a number of expert plumbing technicians.
But take heed: You’ll be working with natural gas, propane or electrical power, all of which are unsafe. If you do not feel great, employ a pro to deal with the tough components. And also have your work evaluated when it’s done.
Plumbing codes differ by area. Describe your planned setup to your local pipes inspector, consisting of the sorts of materials you mean to make use of for your brand-new links. Much better to obtain guidance first so you do not have to change things later on!

Number B: Links for Steel and also Plastic Pipe
FAMILY MEMBERS HANDYMAN
Several houses have galvanized steel or plastic (CPVC) water supply pipelines. Galvanized steel pipes are challenging to replace. We suggest that you remove the pipes back to the nearest tee, screw on a plastic-lined galvanized nipple area and also finish the links with copper as displayed in our image collection.
Because of prospective heat buildup, keep plastic pipeline at the very least 6 in. far from the air vent and also tank. Make a transition from plastic to copper with an unique combining that’s offered wherever CPVC is marketed.
Adaptable copper connectors are easier to mount than solid copper, especially when the existing pipelines and also the tank inlets do not line up. Yet not all local codes enable them. If yours does, take special care not to squeeze or kink them. You can obtain a leak.

Turn off the gas as well as water
Switch off the gas to the hot water heater by turning the nearby shutoff valve a quarter turn. When off, the handle must go to a best angle to the pipe. Shut off the main water system as well and also drain pipes the lines by opening up a faucet on the lowest floor.
Drain pipes the water in the container
Attach a garden tube to the drain valve as well as drain the water left in the tank. Caution: The water will certainly be scalding hot! Detach the gas line at the neighboring union with a pair of wrenches and also loosen the pipeline from the gas control valve with a pipe wrench.
Cut off the water lines
Loosen the vent pipeline from the vent hood and also move it sideways. After that cut 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.) Move the old water heater out of the way.
Affix the safety valve
Wrap the strings of the brand-new temperature level and also stress safety valve with Teflon tape (3 turns). Screw it firmly into the tank with a monkey wrench. Attach a copper discharge pipe (see Fig. A for routing details).
Connect pipe assemblies
Solder new copper adapters to 6-in. sizes of 3/4-in. copper and also screw the assemblies into the hot water outlet and also cool water inlet ports in the top of the container. Add short, plastic lined nipple areas to protect against galvanic corrosion, particularly if you have difficult water or if they’re called for by regional codes.
Affix the water lines
Move the brand-new hot water heater into location, recut or prolong the old tubes to fulfill the new, and also solder the tubing together utilizing copper slip couplings. If the tubing doesn’t align, counter the lines as required with sets of 45-degree elbows.
Reattach the vent
Reconnect the vent. Push it snugly over the draft hood and also slow with 3 3/8-in. No. 6 sheet metal screws. Predrill the holes. The air vent ought to increase a minimum of 12 in. up and down before turning at the very first joint.
Use two wrenches to connect the gas line
Reconnect the gas line. Coat the threaded ends with pipeline joint substance as well as screw the very first nipple area into the gas valve. Usage two monkey wrench to avoid emphasizing the shutoff. Reconstruct the staying nipples, ending up with the union (Image 2). After that adhere to these 4 actions to load the container: (1) Shut the drain shutoff; (2) transform the water back on at the primary shutoff and also open up the cool water valve to the hot water heater (leave it open); (3) switch on a nearby warm water tap up until water comes out; as well as (4) inspect all the joints and installations for water leaks.
Look for backdrafting
The majority of hot water heater depend on a natural draft to attract combustion fumes up the flue. If the draft does not function, those fumes, possibly having dangerous carbon monoxide gas, will certainly spill out right into your home. After completing your setup, inspect the draft.
Close all outside windows and doors and activate your kitchen and bathroom exhaust followers. After that open a close-by hot water faucet till you listen to the burner in the hot water heater spark. After a minute, relocate a smoking match around the edge of the draft hood (Picture 7) in addition to the heating system. The smoke must be formulated the vent pipe. If the smoke doesn’t attract, the fumes from the heater aren’t venting. Shut off the gas to the hot water heater as well as call a licensed plumbing professional to correct the issue.
Look for leaks
Try to find bubbles at connections
Switch on the gas and inspect links for leaks by brushing a 50-50 mix of dishwashing liquid as well as water over the joints. If the mixture bubbles, you have a leakage. Tighten or reconnect joints that leakage. Wipe the joints dry when completed. Call the plumbing inspector to check over your work. Follow the how-to guidance that goes along with the pictures to ensure the links are tight.
Light the pilot light
Make use of a lighter to light the pilot burner
Light the pilot light according to the manufacturer’s directions. (For electric water heaters, transform the power on at the major panel after the electrical assessor checks your work.) Ultimately, set the temperature level to 120 levels F., adhering to the installment guidelines. Light the pilot light in the new water heater and also change the temperature level setup.

Installment Details for Electric Water Heaters
First shut off the power to the hot water heater at your major electrical panel. After that follow the very same draining pipes treatments as for a gas water heater.
When the hot water heater is drained pipes, disconnect the electric cords from the screw terminals under the access panel, which is typically located near the top. (If you do not have electrical experience, employ an electrical contractor to manage all the electric circuitry.)
Follow the producer’s instructions for wiring the brand-new water heater. If the new hot water heater is much shorter and the old cables 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 wires to the box, and after that run a new area of armored cord or electrical avenue to the water heater. Examine the directions and also see to it the ranking of the old fuse or breaker is high enough to handle the brand-new hot water heater. Additionally, the circuit ought to have a shutoff switch within sight of the water heater.
Call your regional electrical assessor before you start the job. You’ll most likely require an authorization. Then, when you’re completed, have the electrical inspector check your work.
Aluminum wiring requires special handling. If you have light weight aluminum electrical wiring, contact a licensed pro that’s certified to deal with it. This wiring is boring gray, not the boring orange that’s characteristic of copper.
Just how to Take care of a Water Heater
Jeff Gorton, an editor at The Family Handyman, will certainly reveal you exactly how to get rid of as well as get rid of a hot water heater in our video tutorial. He will likewise reveal you the easy way to bring a hot water heater out of your residence, also if you are functioning alone.
These ideas will make your work go much faster and also easier:
Gauge the height of your old hot water heater and also buy a new one the very same elevation so you do not have to change the length of the water, gas or electric lines.
The drain valve (Picture 2) on old hot water heater frequently blocks. If the water drains slowly, be patient. CARE: It’s scalding warm! SUGGESTION: Transform your hot water heater off two hours beforehand to allow the water to cool.
Water heaters consider regarding 150 pounds. You’ll need a solid assistant or a dolly when you move the old one out and wheel the brand-new one in. Waste solutions commonly charge regarding $25 to take the old one. Innovative Plumbing & Drain
Prior to you start, acquire the tools and also materials revealed below at a pipes supply or equipment shop or a home facility. Inspect the sizes of the water pipes (most will certainly be 3/4 in. like the ones in our photos) and also buy the right-size fittings. With whatever available, you’ll need 4 to 6 hours to complete the job (thinking no huge drawbacks!).
The temperature as well as pressure relief valve is a safety and security tool that restricts container pressure as well as maintains it from blowing up (Picture 4). A brand-new one have to be consisted of with every setup. For the shutoff to work correctly, the discharge pipeline must be maintained devoid of obstructions (Fig. A).
In areas with highly mineralized water, or where required by local codes, utilize 3/4-in. plastic-lined nipples (about $2 each; Picture 5 and also Fig. A) for joining different steels, usually copper tubing to the steel container. This reduces rust.
When attaching the water lines, solder the copper fittings prior to you screw them to the tank so you don’t warm the tank itself while soldering (Photo 5).
Use “slip” couplings to link the old and brand-new lines (Photo 6). Unlike routine combinings, they don’t have an internal stop. You can glide them on, align the copper tubing, then slide them back as well as focus them over the joint.
The new inlets and also outlets on the tank don’t constantly associate the old supply lines. Solder in a pair of 45-degree fittings to offset each line if necessary. Additionally change the old shutoff valve with a brand-new round valve while you’re at it (Picture 6). Vent diameters are sized according to the warmth outcome of the hot water heater. You might have to boost or reduce the air vent dimension to ensure the very best draft. CARE: If you’re unsure if your chimney has a lining, ask your plumbing assessor. Innovative Plumbing & & Drain
Make gas links with strong steel pipe (Image 8) or soft copper with flare installations (Fig. A). Both are more reliable as well as cheaper than flexible stainless-steel connectors, which are not constantly allowed. Usage inflexible copper as opposed to adaptable copper water supply lines for the exact same factors.
If you find your hot water heater substitute where leakage can create damage to the floor or various other components of the house, set a pan of an authorized size under it (steel for gas water heaters). The pan needs to have a drain tube that causes a house drain or other authorized place (outdoors where allowed). The temperature as well as stress safety valve discharge tube additionally have to cause a drainpipe if leak would damage the floors. If routing is challenging, review alternatives with your local plumbing inspector.
If you live in an earthquake-prone area, band the hot water heater to the wall with unique straps (Fig. A; offered at pipes stores and also home centers). Your plumbing examiner will tell you if they’re called for.
Set the brand-new water temperature readying to no greater than 120 levels F. to stay clear of scalding.
