When to obtain a new hot water heater
Your hot water heater is dead when the tank leaks. The dead giveaway that your water heater needs replacing is a sluggish drip beneath, typically turning up as a path of corroded water. This implies that the steel storage tank has actually rusted with and also can not be dealt with. Other signs and symptoms, such as inadequate or no warm water, generally signal various other water heater repair work troubles that you can repair.
If you find a drip, plan to replace the hot water heater as soon as possible. Don’t wait till the leakage gets poor.
New water heaters feature installment guidelines and also great deals of warnings to make sure you deal with the gas, electric and various other links safely. In this post, we’ll supplement those basics with techniques as well as “real world” recommendations from several professional plumbings.
However take heed: You’ll be dealing with natural gas, gas or electrical energy, every one of which are harmful. If you don’t feel great, call a pro to deal with the tough components. And also have your work evaluated when it’s done.
Pipes codes vary by region. Define your prepared installation to your local pipes inspector, including the types of products you mean to make use of for your new connections. Much better to get assistance first so you do not have to transform points later!
Number A: Gas Water Heater Particulars
To print out this photo, see the Additional Info at the end of this write-up.
Number B: Links for Steel as well as Plastic Pipeline
Lots of homes have galvanized steel or plastic (CPVC) water system pipes. Galvanized steel pipelines are tough to change. We advise that you get rid of the pipelines back to the closest tee, screw on a plastic-lined galvanized nipple and also finish the connections with copper as displayed in our image series.
Due to prospective warm build-up, maintain plastic pipe at the very least 6 in. away from the air vent and also storage tank. Make a change from plastic to copper with an unique coupling that’s offered any place CPVC is offered.
Versatile copper connectors are less complicated to mount than strong copper, specifically when the existing pipelines and the tank inlets don’t line up. Yet not all neighborhood codes allow them. If your own does, take unique care not to squeeze or kink them. You can obtain a leakage.

Turn off the gas as well as water
Shut off the gas to the hot water heater by transforming the nearby shutoff valve a quarter turn. When off, the manage need to be at a right angle to the pipeline. Turn off the primary water system too as well as drain the lines by opening up a tap on the lowest flooring.
Drain pipes the water in the storage tank
Connect a yard tube to the drain valve as well as drain the water left in the storage tank. Caution: The water will certainly be scalding hot! Disconnect the gas line at the neighboring union with a pair of wrenches as well as loosen the pipe from the gas control shutoff with a pipe wrench.
Cut off the water lines
Loosen the air vent pipe from the vent hood and also move it to the side. After that cut the cold and hot water lines with a tube cutter. (Unscrew unions for galvanized pipe or the nuts on flexible adapters if you have them.) Slide the old hot water heater off the beaten track.
Attach the relief valve
Wrap the strings of the new temperature level as well as pressure relief valve with Teflon tape (3 turns). Screw it tightly into the storage tank with a pipe wrench. Attach a copper discharge pipeline (see Fig. A for directing details).
Affix pipeline settings up
Solder new copper adapters to 6-in. lengths of 3/4-in. copper and screw the assemblies into the hot water electrical outlet and chilly water inlet ports in the top of the storage tank. Include short, plastic lined nipples to secure versus galvanic deterioration, specifically if you have difficult water or if they’re called for by regional codes.
Attach the water lines
Move the brand-new water heater into location, recut or expand the old tubes to fulfill the new, and solder the tubes with each other using copper slip couplings. If the tubes doesn’t line up, balance out the lines as required with pairs of 45-degree elbow joints.
Reattach the vent
Reconnect the air vent. Push it firmly over the draft hood and also anchor it with 3 3/8-in. No. 6 sheet metal screws. Predrill the holes. The vent must rise a minimum of 12 in. up and down before turning at the initial arm joint.
Use two wrenches to attach the gas line
Reconnect the gas line. Cover the threaded ends with pipeline joint compound as well as screw the first nipple right into the gas valve. Usage 2 pipe wrenches to stay clear of stressing the shutoff. Rebuild the staying nipples, ending up with the union (Picture 2). Then follow these four actions to fill the storage tank: (1) Shut the drain valve; (2) turn the water back on at the main shutoff and also open the cool water shutoff to the water heater (leave it open); (3) switch on a nearby hot water tap until water comes out; and also (4) inspect all the joints as well as installations for water leaks.
Look for backdrafting
A lot of water heaters rely upon an all-natural draft to draw combustion fumes up the flue. If the draft does not function, those fumes, potentially consisting of harmful carbon monoxide gas, will spill out into your residence. After completing your setup, inspect the draft.
Close all outside doors and windows as well as switch on your bathroom and kitchen exhaust fans. After that open up a neighboring hot water faucet up until you hear the burner in the hot water heater fire up. After a minute, relocate a cigarette smoking match around the edge of the draft hood (Picture 7) on top of the heating unit. The smoke ought to be drawn up the vent pipe. If the smoke doesn’t draw, the fumes from the heater aren’t airing vent. Switch off the gas to the water heater and also call an accredited plumbing to correct the trouble.
Look for leakages
Look for bubbles at links
Switch on the gas and inspect links for leakages by cleaning a 50-50 combination of dishwashing fluid and also water over the joints. If the combination bubbles, you have a leak. Tighten or reconnect joints that leak. Clean the joints dry when ended up. Call the pipes assessor to check out your work. Comply with the how-to recommendations that goes along with the photos to make certain the connections are tight.
Light the pilot burner
Make use of a lighter to light the pilot light
Light the pilot light according to the maker’s directions. (For electrical water heaters, transform the power on at the main panel after the electric inspector checks your job.) Lastly, established the temperature to 120 levels F., complying with the installment guidelines. Light the pilot light in the brand-new water heater as well as change the temperature level setup.

Installment Details for Electric Water Heaters
First shut off the power to the hot water heater at your main electrical panel. After that adhere to the same draining pipes procedures as for a gas water heater.
When the water heater is drained pipes, detach the electrical wires from the screw terminals under the access panel, which is normally found near the top. (If you do not have electric experience, employ an electrical contractor to manage all the electrical circuitry.)
Follow the producer’s directions for wiring the new hot water heater. If the brand-new water heater is shorter as well as the old cords won’t reach, surface-mount a 4-in. x 4-in. x 1-1/2 in. steel electric box on the wall surface or ceiling close by, run the old cables to package, and after that run a new area of armored wire or electrical channel to the hot water heater. Inspect the instructions and ensure the ranking of the old fuse or circuit breaker is high sufficient to manage the new hot water heater. Furthermore, the circuit should have a shutoff button within sight of the water heater.
Call your regional electric inspector before you start the work. You’ll possibly need an authorization. Then, when you’re completed, have the electrical assessor inspect your work.
Aluminum electrical wiring requires special handling. If you have light weight aluminum electrical wiring, contact a certified pro who’s accredited to work with it. This wiring is boring gray, not the plain orange that’s particular of copper.
How to Get rid of a Hot Water Heater
Jeff Gorton, an editor at The Household Handyman, will certainly reveal you exactly how to remove and also get rid of a water heater in our video clip tutorial. He will certainly likewise reveal you the very easy means to carry a water heater out of your home, even if you are functioning alone.
These ideas will make your job go much faster as well as easier:
Measure the elevation of your old water heater and also acquire a brand-new one the exact same height so you do not need to change the size of the water, gas or electrical lines.
The drainpipe shutoff (Picture 2) on old hot water heater commonly clogs up. If the water drains slowly, be patient. CARE: It’s scalding warm! TIP: Turn your water heater off 2 hours ahead of time to permit the water to cool down.
Water heaters consider regarding 150 lbs. You’ll require a strong assistant or a dolly when you relocate the old one out and also wheel the new one in. Trash solutions generally bill about $25 to take the old one. Innovative Plumbing & Drain
Prior to you begin, acquire the tools as well as products shown right here at a plumbing supply or equipment store 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 buy the right-size installations. With every little thing handy, you’ll need four to six hours to finish the job (thinking no large drawbacks!).
The temperature as well as pressure safety valve is a safety tool that limits container pressure and maintains it from taking off (Picture 4). A brand-new one must be included with every installment. For the valve to work effectively, the discharge pipeline need to be maintained free of blockages (Fig. A).
In areas with extremely mineralized water, or where required by regional codes, make use of 3/4-in. plastic-lined nipples (concerning $2 each; Photo 5 as well as Fig. A) for joining various steels, normally copper tubes to the steel tank. This reduces deterioration.
When linking the water lines, solder the copper fittings before you screw them to the tank so you don’t warm the storage tank itself while soldering (Photo 5).
Use “slip” couplings to connect the old and new lines (Photo 6). Unlike regular couplings, they do not have an internal stop. You can move them on, align the copper tubes, after that move them back and also focus them over the joint.
The new inlets as well as electrical outlets on the tank don’t always associate the old supply lines. Solder in a pair of 45-degree installations to offset each line if needed. Additionally change the old shutoff valve with a new sphere valve while you go to it (Image 6). Vent sizes are sized according to the warm outcome of the water heater. You could need to increase or reduce the vent dimension to guarantee the very best draft. CARE: If you’re unclear if your chimney has a lining, ask your pipes examiner. Ingenious Plumbing & & Drainpipe
Make gas links with strong steel pipeline (Picture 8) or soft copper with flare installations (Fig. A). Both are more trustworthy and also cheaper than versatile stainless steel connectors, which are not always permitted. Usage stiff copper instead of adaptable copper supply of water lines for the very same reasons.
If you locate your water heater substitute where leak can cause damage to the floor or various other components of your home, set a pan of an authorized dimension under it (steel for gas water heaters). The pan needs to have a drainpipe tube that brings about a residence drainpipe or various other approved area (outdoors where permitted). The temperature level and also pressure safety valve discharge tube likewise have to bring about a drainpipe if leakage would certainly harm the floors. If directing is difficult, go over choices with your local pipes examiner.
If you stay in an earthquake-prone area, strap the hot water heater to the wall with special bands (Fig. A; available at pipes stores and also residence centers). Your plumbing inspector will certainly tell you if they’re required.
Set the brand-new water temperature level readying to no greater than 120 degrees F. to stay clear of hot.
