When to obtain a new hot water heater

Your water heater is dead when the tank leaks. The telltale sign that your hot water heater needs changing is a slow drip underneath, generally appearing as a trail of rusty water. This indicates that the steel tank has rusted via and also can’t be fixed. Various other signs, such as not enough or no hot water, normally signal other water heater repair issues that you can fix.

If you detect a drip, plan to replace the water heater right now. Do not wait until the leak obtains negative.

New water heaters come with installment instructions as well as lots of warnings to make certain you handle the gas, electric and various other links safely. In this short article, we’ll supplement those essentials with strategies and also “real world” guidance from numerous specialist plumbing technicians.

Yet take heed: You’ll be collaborating with gas, propane or power, all of which are hazardous. If you do not feel great, hire a professional to deal with the challenging components. And also have your job evaluated when it’s done.

Number A: Gas Hot Water Heater Details



To print out this picture, see the Extra Details at the end of this post.

Figure B: Links for Steel and also Plastic Pipe


Numerous homes have galvanized steel or plastic (CPVC) supply of water pipelines. Galvanized steel pipelines are hard to change. We recommend that you remove the pipes back to the local tee, screw on a plastic-lined galvanized nipple area and complete the links with copper as received our photo series.

Due to prospective heat accumulation, maintain plastic pipe at the very least 6 in. far from the vent and container. Make a transition from plastic to copper with a special combining that’s available anywhere CPVC is sold.

Versatile copper adapters are simpler to set up than strong copper, particularly when the existing pipelines as well as the tank inlets do not align. However not all neighborhood codes permit them. If your own does, take special treatment not to pinch or kink them. You might get a leakage.

Task detailed (12 )

Step 1

Turn off the gas and also water


Shut off the gas to the hot water heater by turning the neighboring shutoff valve a quarter turn. When off, the manage should be at a best angle to the pipeline. Turn off the primary supply of water too and also drain pipes the lines by opening a faucet on the most affordable floor.

Action 2

Drain pipes the water in the tank


Connect a garden hose pipe to the drainpipe shutoff and also drain the water left in the tank. Care: The water will certainly be scalding warm! Separate the gas line at the neighboring union with a set of wrenches and loosen the pipe from the gas control valve with a monkey wrench.

Action 3

Cut off the water lines


Loosen the air vent pipe from the vent hood as well as 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 versatile connectors if you have them.) Slide the old water heater out of the way.

Tip 4

Affix the safety valve


Cover the threads of the brand-new temperature and pressure relief valve with Teflon tape (three turns). Screw it securely right into the tank with a pipe wrench. Attach a copper discharge pipeline (see Fig. A for routing details).

Step 5

Connect pipe settings up


Solder brand-new copper adapters to 6-in. lengths of 3/4-in. copper and also screw the assemblies right into the warm water outlet as well as cold water inlet ports in the top of the storage tank. Add short, plastic lined nipples to protect versus galvanic rust, especially if you have tough water or if they’re required by neighborhood codes.

Step 6

Attach the water lines


Slide the brand-new hot water heater into area, recut or extend the old tubes to meet the new, and solder the tubing with each other utilizing copper slip couplings. If the tubes doesn’t line up, counter the lines as needed with pairs of 45-degree arm joints.

Action 7

Reattach the air vent


Reconnect the air vent. Shove it firmly over the draft hood and slow with 3 3/8-in. No. 6 sheet metal screws. Predrill the holes. The vent need to rise at least 12 in. up and down before turning at the first elbow joint.

Tip 8

Usage 2 wrenches to connect the gas line


Reconnect the gas line. Cover the threaded ends with pipe joint substance and also screw the initial nipple into the gas shutoff. Usage 2 pipe wrenches to avoid emphasizing the shutoff. Rebuild the remaining nipple areas, finishing up with the union (Picture 2). After that adhere to these 4 actions to fill up the container: (1) Close the drain valve; (2) transform the water back on at the major shutoff as well as open the chilly water valve to the hot water heater (leave it open); (3) activate a nearby warm water faucet until water comes out; as well as (4) evaluate all the joints as well as installations for water leaks.

Step 9

Check for backdrafting

A lot of water heaters depend on an all-natural draft to attract combustion fumes up the flue. If the draft does not work, those fumes, potentially consisting of harmful carbon monoxide, will certainly spill out right into your house. After completing your installment, inspect the draft.

Close all external doors and windows and activate your bathroom and kitchen exhaust followers. Then open up a close-by hot water tap till you hear the burner in the water heater ignite. After a min, move a smoking suit around the side of the draft hood (Photo 7) in addition to the heating system. The smoke must be created the air vent pipe. If the smoke does not draw, the fumes from the burner aren’t airing vent. Turn off the gas to the hot water heater and call a licensed plumbing technician to fix the trouble.

Action 10

Check for leakages

Try to find bubbles at links


Turn on the gas and check connections for leaks by cleaning a 50-50 blend of dishwashing liquid and also water over the joints. If the blend bubbles, you have a leak. Tighten up or reconnect joints that leakage. Wipe the joints completely dry when ended up. Call the plumbing assessor to check over your work. Adhere to the how-to recommendations that comes with the photos to ensure the links are limited.

Step 11

Light the pilot burner

Use a lighter to light the pilot burner


Light the pilot burner according to the maker’s instructions. (For electrical hot water heater, transform the power on at the main panel after the electric examiner checks your work.) Ultimately, established the temperature to 120 levels F., complying with the setup guidelines. Light the pilot light in the brand-new water heater as well as change the temperature level setting.

Installment Information for Electric Water Heaters

First shut off the power to the water heater at your main electric panel. After that follow the exact same draining pipes treatments when it comes to a gas hot water heater.

When the water heater is drained, detach the electrical cords from the screw terminals under the accessibility panel, which is typically found near the top. (If you do not have electric experience, employ an electrical contractor to handle all the electric circuitry.)

Adhere to the producer’s instructions for wiring the new hot water heater. If the brand-new water heater is shorter and also 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 cords to package, and afterwards run a brand-new area of armored cable television or electric channel to the hot water heater. Check the directions as well as see to it the ranking of the old fuse or breaker is high enough to take care of the brand-new hot water heater. In addition, the circuit must have a shutoff button within sight of the hot water heater.

Call your regional electric assessor prior to you begin the job. You’ll possibly need an authorization. Then, when you’re finished, have the electric assessor examine your job.

Light weight aluminum circuitry calls for special handling. If you have light weight aluminum wiring, call an accredited pro that’s licensed to work with it. This electrical wiring is plain grey, not the plain orange that’s characteristic of copper.

Exactly how to Get rid of a Hot Water Heater

Jeff Gorton, an editor at The Family members Handyman, will show you just how to get rid of and take care of a water heater in our video clip tutorial. He will certainly likewise show you the very easy way to bring a water heater out of your house, even if you are functioning alone.

These pointers will make your work go faster and also easier:

Measure the elevation of your old hot water heater and purchase a brand-new one the same elevation so you do not need to transform the size of the water, gas or electrical lines.

The drainpipe valve (Photo 2) on old hot water heater typically congests. If the water drains slowly, hold your horses. CARE: It’s scalding warm! TIP: Transform your hot water heater off 2 hours ahead of time to permit the water to cool down.

Water heaters evaluate 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. Rubbish solutions typically bill concerning $25 to take the old one. Innovative Plumbing & Drain

Prior to you begin, purchase the tools as well as products revealed right here at a pipes supply or equipment shop or a house facility. Check the dimensions of the supply of water pipes (most will be 3/4 in. like the ones in our pictures) and also acquire the right-size fittings. With whatever accessible, you’ll require 4 to six hrs to complete the task (thinking no large hitches!).

The temperature level and pressure relief valve is a safety and security tool that restricts tank pressure and maintains it from taking off (Photo 4). A new one should be consisted of with every installation. For the valve to work correctly, the discharge pipeline need to be kept devoid of obstructions (Fig. A).

In areas with very mineralized water, or where needed by local codes, use 3/4-in. plastic-lined nipples (about $2 each; Photo 5 and Fig. A) for joining different steels, usually copper tubing to the steel storage tank. This reduces rust.

When linking the water lines, solder the copper installations prior to you screw them to the container so you don’t heat the container itself while soldering (Photo 5).

Use “slip” combinings to connect the old and also brand-new lines (Image 6). Unlike routine couplings, they do not have an interior stop. You can move them on, align the copper tubes, after that glide them back and also center them over the joint.

The brand-new inlets as well as outlets on the tank do not constantly line up with the old supply lines. Solder in a pair of 45-degree fittings to balance out each line if needed. Also change the old shutoff valve with a brand-new sphere valve while you’re at it (Photo 6). Vent sizes are sized according to the heat outcome of the hot water heater. You may need to boost or reduce the vent dimension to guarantee the very best draft. CAUTION: If you’re unsure if your smokeshaft has a lining, ask your plumbing inspector. Innovative Pipes & & Drain

Make gas connections with strong steel pipe (Picture 8) or soft copper with flare installations (Fig. A). Both are much more reliable and also less expensive than flexible stainless-steel adapters, which are not always permitted. Use inflexible copper as opposed to flexible copper water system lines for the exact same factors.

If you situate your hot water heater substitute where leakage can trigger damages to the floor or other components of the house, set a pan of an authorized size under it (metal for gas water heaters). The frying pan should have a drain tube that results in a house drainpipe or various other approved place (outdoors where allowed). The temperature level as well as pressure safety valve discharge tube likewise must bring about a drain if leakage would certainly damage the floors. If directing is tough, go over choices with your local pipes examiner.

If you stay in an earthquake-prone region, strap the hot water heater to the wall with unique bands (Fig. A; offered at plumbing shops and also house centers). Your plumbing inspector will tell you if they’re called for.

Establish the brand-new water temperature level setting to no more than 120 degrees F. to stay clear of hot.
