When to get a new hot water heater
Your water heater is dead when the storage tank leakages. The telltale sign that your water heater needs replacing is a sluggish drip underneath, typically turning up as a trail of rustic water. This means that the steel storage tank has actually rusted through as well as can not be fixed. Other symptoms, such as not enough or no hot water, typically signal other water heater fixing problems that you can fix.
If you spot a drip, plan to replace the water heater today. Don’t wait till the leakage gets negative.
New water heaters feature installation guidelines and lots of cautions to see to it you manage the gas, electrical and other links securely. In this article, we’ll supplement those basics with techniques and also “real life” suggestions from numerous expert plumbing professionals.
But take heed: You’ll be working with natural gas, lp or electrical energy, every one of which are harmful. If you do not feel great, contact a professional to look after the challenging parts. And have your job examined when it’s done.
Pipes codes vary by region. Explain your intended installation to your regional pipes examiner, including the sorts of materials you mean to make use of for your new connections. Better to obtain advice initially so you do not have to transform points later on!

FAMILY MEMBERS HANDYMAN
Many houses have galvanized steel or plastic (CPVC) water system pipelines. Galvanized steel pipelines are tough to replace. We advise that you remove the pipelines back to the closest tee, screw on a plastic-lined galvanized nipple area as well as finish the connections with copper as shown in our image collection.
Due to possible warmth build-up, maintain plastic pipeline a minimum of 6 in. away from the vent and container. Make a shift from plastic to copper with an unique coupling that’s available wherever CPVC is offered.
Versatile copper connectors are less complicated to install than strong copper, especially when the existing pipes and also the storage tank inlets do not align. But not all neighborhood codes enable them. If your own does, take special treatment not to pinch or kink them. You can get a leakage.

Shut down the gas and water
Shut off the gas to the hot water heater by turning the neighboring shutoff valve a quarter turn. When off, the deal with must go to a right angle to the pipe. Turn off the main water too as well as drain the lines by opening a faucet on the lowest floor.
Drain the water in the storage tank
Connect a garden pipe to the drainpipe shutoff and also drain the water left in the container. Care: The water will be scalding warm! 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 monkey wrench.
Cut off the water lines
Unscrew the vent pipeline from the vent hood and also move it to the side. After that reduce the hot and cold water lines with a tube cutter. (Unscrew unions for galvanized pipe or the nuts on adaptable adapters if you have them.) Move the old hot water heater off the beaten track.
Attach the relief valve
Cover the strings of the brand-new temperature level and stress safety valve with Teflon tape (three turns). Screw it firmly right into the storage tank with a monkey wrench. Affix a copper discharge pipe (see Fig. A for directing details).
Affix pipe assemblies
Solder brand-new copper adapters to 6-in. sizes of 3/4-in. copper as well as screw the assemblies into the hot water outlet and chilly water inlet ports in the top of the tank. Add short, plastic lined nipples to protect against galvanic rust, particularly if you have difficult water or if they’re required by regional codes.
Connect the water lines
Move the new hot water heater into location, recut or extend the old tubes to fulfill the new, as well as solder the tubes with each other utilizing copper slip combinings. If the tubes doesn’t align, counter the lines as needed with sets of 45-degree arm joints.
Reattach the vent
Reconnect the air vent. Push it securely over the draft hood as well as slow with 3 3/8-in. No. 6 sheet steel screws. Predrill the holes. The vent need to increase at least 12 in. up and down before turning at the very first joint.
Usage two wrenches to affix the gas line
Reconnect the gas line. Coat the threaded ends with pipeline joint substance and also screw the initial nipple area into the gas valve. Usage two monkey wrench to avoid worrying the valve. Rebuild the remaining nipples, finishing up with the union (Image 2). Then comply with these 4 actions to fill the storage tank: (1) Close the drainpipe valve; (2) turn the water back on at the primary shutoff as well as open the cold water shutoff to the water heater (leave it open); (3) turn on a close-by hot water tap until water appears; as well as (4) examine all the joints as well as fittings for water leakages.
Check for backdrafting
A lot of water heaters count on a natural draft to attract burning fumes up the flue. If the draft does not function, those fumes, possibly consisting of dangerous carbon monoxide gas, will splash out right into your home. After finishing your setup, check the draft.
Close all outside doors and windows and switch on your bathroom and kitchen exhaust followers. After that open a nearby hot water tap till you hear the burner in the hot water heater spark. After a minute, move a smoking cigarettes match around the side of the draft hood (Photo 7) on top of the heating system. The smoke needs to be created the vent pipeline. If the smoke doesn’t draw, the fumes from the burner aren’t venting. Shut off the gas to the water heater and also call a certified plumbing technician to deal with the issue.
Look for leaks
Search for bubbles at links
Switch on the gas and examine connections for leaks by brushing a 50-50 mixture of dishwashing liquid as well as water over the joints. If the mixture bubbles, you have a leakage. Tighten or reconnect joints that leakage. Clean the joints dry when completed. Call the pipes assessor to check out your work. Comply with the how-to guidance that comes with the pictures to make certain the connections are limited.
Light the pilot burner
Utilize a lighter to light the pilot burner
Light the pilot light according to the maker’s directions. (For electrical hot water heater, transform the power on at the primary panel after the electric inspector checks your job.) Lastly, set the temperature to 120 degrees F., complying with the installation directions. Light the pilot burner in the brand-new hot water heater and adjust the temperature level setting. Innovative Plumbing & Drain
Setup Details for Electric Water Heaters
First turn off the power to the water heater at your major electric panel. Then follow the same draining treatments when it comes to a gas hot water heater.
When the water heater is drained, disconnect the electric cables from the screw terminals under the access panel, which is normally situated near the top. (If you do not have electrical experience, employ an electrical contractor to handle all the electrical circuitry.)
Follow the maker’s directions for electrical wiring the new water heater. If the new hot water heater is much shorter and also the old cords won’t reach, surface-mount a 4-in. x 4-in. x 1-1/2 in. metal electric box on the wall or ceiling close by, run the old cables to the box, and after that run a new area of armored cord or electric channel to the water heater. Check the guidelines and also make sure the ranking of the old fuse or breaker is high sufficient to deal with the brand-new hot water heater. Additionally, the circuit ought to have a shutoff button within view of the hot water heater.
Call your regional electrical assessor before you begin the job. You’ll probably require a permit. After that, when you’re ended up, have the electric examiner check your job.
Light weight aluminum circuitry calls for special delivery. If you have aluminum circuitry, call in a certified pro who’s licensed to collaborate with it. This circuitry is plain gray, not the plain orange that’s characteristic of copper.
Exactly how to Deal with a Water Heater
Jeff Gorton, an editor at The Household Handyman, will reveal you just how to eliminate as well as throw away a water heater in our video clip tutorial. He will certainly additionally show you the simple way to lug a water heater out of your residence, also if you are functioning alone.
These pointers will certainly make your work go faster and easier:
Gauge the height of your old hot water heater and acquire a brand-new one the same height so you do not have to alter the length of the water, gas or electric lines.
The drainpipe shutoff (Picture 2) on old water heaters frequently clogs up. If the water drains slowly, hold your horses. CAUTION: It’s scalding warm! SUGGESTION: Transform your hot water heater off two hrs ahead of time to enable the water to cool.
Hot water heater evaluate regarding 150 lbs. You’ll require a strong assistant or a dolly when you move the old one out and also wheel the brand-new one in. Waste solutions generally charge concerning $25 to take the old one. Innovative Plumbing & Drain
Before you begin, buy the devices as well as products shown here at a plumbing supply or equipment shop or a home facility. Check the dimensions of the water pipelines (most will be 3/4 in. like the ones in our images) as well as acquire the right-size fittings. With everything handy, you’ll require four to 6 hrs to complete the work (assuming no big hitches!).
The temperature level and stress relief valve is a safety and security gadget that limits tank pressure and keeps it from taking off (Image 4). A new one need to be included with every installment. For the shutoff to work effectively, the discharge pipe need to be maintained devoid of obstructions (Fig. A).
In areas with very mineralized water, or where called for by neighborhood codes, make use of 3/4-in. plastic-lined nipple areas (about $2 each; Photo 5 and also Fig. A) for joining different metals, normally copper tubes to the steel storage tank. This reduces corrosion.
When linking the water lines, solder the copper fittings before you screw them to the storage tank so you do not heat the container itself while soldering (Picture 5).
Use “slip” combinings to link the old and also new lines (Image 6). Unlike normal combinings, they do not have an inner stop. You can glide them on, straighten the copper tubes, after that slide them back and focus them over the joint.
The brand-new inlets as well as outlets on the storage tank do not always associate the old supply lines. Solder in a pair of 45-degree installations to counter each line if essential. Likewise replace the old shutoff valve with a new sphere valve while you’re at it (Picture 6). Air vent diameters are sized according to the warmth result of the water heater. You could have to enhance or decrease the air vent size to make sure the very best draft. CAUTION: If you’re uncertain if your smokeshaft has a lining, ask your plumbing assessor. Innovative Plumbing & & Drainpipe
Make gas links with strong steel pipe (Picture 8) or soft copper with flare fittings (Fig. A). Both are more dependable and also cheaper than flexible stainless steel adapters, which are not always permitted. Usage stiff copper instead of adaptable copper supply of water lines for the very same reasons.
If you find your water heater substitute where leakage could cause damages to the floor or various other components of the house, set a pan of an accepted dimension under it (metal for gas water heaters). The pan should have a drain tube that causes a residence drainpipe or other approved location (outdoors where allowed). The temperature level as well as stress relief valve discharge tube likewise have to bring about a drainpipe if leak would certainly harm the floorings. If directing is tough, talk about alternatives with your regional plumbing examiner.
If you stay in an earthquake-prone area, strap the hot water heater to the wall with special straps (Fig. A; available at plumbing stores and house facilities). Your pipes assessor will tell you if they’re needed.
Set the brand-new water temperature level readying to no greater than 120 levels F. to stay clear of hot.
