When to obtain a new water heater
Your water heater is dead when the container leaks. The telltale sign that your water heater requires replacing is a slow drip below, generally appearing as a path of rusty water. This implies that the steel storage tank has rusted with and also can not be dealt with. Other signs and symptoms, such as insufficient or no warm water, generally signal various other water heater fixing problems that you can fix.
If you identify a drip, plan to replace the water heater as soon as possible. Do not wait until the leakage gets bad.
New hot water heater include setup guidelines and great deals of cautions to see to it you deal with the gas, electrical and other connections securely. In this post, we’ll supplement those fundamentals with techniques and also “real world” recommendations from numerous expert plumbing professionals.
Yet take heed: You’ll be dealing with natural gas, lp or electrical power, all of which are dangerous. If you do not feel confident, contact a pro to look after the hard components. And have your work inspected when it’s done.
Pipes codes differ by region. Define your intended setup to your neighborhood plumbing examiner, consisting of the sorts of products you mean to make use of for your brand-new connections. Better to get guidance first so you do not need to change things later!
Number A: Gas Water Heater Details
To print out this picture, see the Additional Information at the end of this article.
Figure B: Links for Steel and also Plastic Pipe
Many residences have galvanized steel or plastic (CPVC) water pipelines. Galvanized steel pipelines are difficult to replace. We advise that you eliminate the pipes back to the nearest tee, screw on a plastic-lined galvanized nipple area and complete the links with copper as shown in our image collection.
As a result of possible heat accumulation, keep plastic pipe a minimum of 6 in. far from the vent as well as tank. Make a shift from plastic to copper with a special combining that’s available any place CPVC is marketed.
Adaptable copper connectors are less complicated to install than strong copper, particularly when the existing pipes and the container inlets don’t align. However not all regional codes enable them. If yours does, take special treatment not to pinch or kink them. You might get a leakage.

Project step-by-step (12 )
Turn off the gas and 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 must be at an ideal angle to the pipe. Shut off the main water system also as well as drain pipes the lines by opening a faucet on the lowest floor.
Drain pipes the water in the container
Connect a yard hose to the drainpipe shutoff as well as drain the water left in the storage tank. Care: The water will certainly be scalding hot! Separate the gas line at the close-by union with a pair of wrenches as well as loosen the pipe from the gas control shutoff with a monkey wrench.
Cut off the water lines
Loosen the vent pipeline from the air vent hood as well as relocate 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 versatile adapters if you have them.) Move the old water heater out of the way.
Connect the relief valve
Wrap the threads of the brand-new temperature and also pressure safety valve with Teflon tape (three turns). Screw it firmly right into the storage tank with a monkey wrench. Connect a copper discharge pipeline (see Fig. A for directing information).
Attach pipeline assemblies
Solder brand-new copper adapters to 6-in. sizes of 3/4-in. copper and also screw the assemblies into the hot water electrical outlet as well as cool water inlet ports in the top of the storage tank. Include short, plastic lined nipples to secure against galvanic rust, especially if you have tough water or if they’re required by regional codes.
Attach the water lines
Move the new hot water heater into place, recut or prolong the old tubing to fulfill the new, and solder the tubing with each other using copper slip combinings. If the tubes does not line up, counter the lines as needed with pairs of 45-degree elbows.
Reattach the air vent
Reconnect the air vent. Shove it tightly over the draft hood and also slow with 3 3/8-in. No. 6 sheet metal screws. Predrill the holes. The vent must rise at least 12 in. vertically before turning at the first elbow.
Use 2 wrenches to affix the gas line
Reconnect the gas line. Coat the threaded ends with pipe joint substance and also screw the very first nipple area right into the gas valve. Usage 2 monkey wrench to avoid stressing the valve. Reassemble the remaining nipples, ending up with the union (Image 2). After that comply with these 4 actions to fill the storage tank: (1) Close the drainpipe valve; (2) transform the water back on at the primary shutoff and also open up the cold water valve to the hot water heater (leave it open); (3) switch on a neighboring warm water tap until water appears; as well as (4) evaluate all the joints and also installations for water leaks.
Look for backdrafting
A lot of hot water heater rely upon a natural draft to draw combustion fumes up the flue. If the draft doesn’t function, those fumes, perhaps including fatal carbon monoxide gas, will certainly splash out into your home. After completing your installment, check the draft.
Close all exterior doors and windows and activate your kitchen and bathroom exhaust fans. After that open a close-by warm water faucet until you hear the gas burner in the water heater fire up. After a minute, relocate a cigarette smoking match around the side of the draft hood (Photo 7) in addition to the heating system. The smoke ought to be drawn up the air vent pipe. If the smoke doesn’t draw, the fumes from the burner aren’t venting. Shut off the gas to the water heater and call an accredited plumbing to correct the trouble.
Look for leaks
Seek bubbles at links
Turn on the gas and also examine links for leaks by cleaning a 50-50 mix of dishwashing liquid as well as water over the joints. If the blend bubbles, you have a leak. Tighten 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 photos to make sure the connections are tight.
Light the pilot light
Make use of a lighter to light the pilot light
Light the pilot burner according to the supplier’s directions. (For electric hot water heater, transform the power on at the primary panel after the electrical inspector checks your job.) Finally, set the temperature level to 120 levels F., following the installment guidelines. Light the pilot light in the brand-new water heater and adjust the temperature setup.

Setup Information for Electric Water Heaters
First switch off the power to the water heater at your primary electric panel. After that adhere to the same draining pipes treatments as for a gas hot water heater.
When the hot water heater is drained pipes, detach the electrical cables from the screw terminals under the access panel, which is generally situated near the top. (If you don’t have electrical experience, hire an electrical expert to manage all the electric wiring.)
Follow the supplier’s instructions for wiring the new hot water heater. If the brand-new water heater is much shorter as well as the old wires will not reach, surface-mount a 4-in. x 4-in. x 1-1/2 in. steel electric box on the wall or ceiling nearby, run the old cables to package, and afterwards run a new area of armored cable television or electrical conduit to the water heater. Examine the directions and also see to it the ranking of the old fuse or circuit breaker is high sufficient to manage the new hot water heater. In addition, the circuit ought to have a shutoff switch within sight of the water heater.
Call your neighborhood electric examiner before you start the task. You’ll probably require a permit. After that, when you’re ended up, have the electrical assessor check your work.
Aluminum circuitry calls for special delivery. If you have aluminum circuitry, call in a qualified pro that’s accredited to deal with it. This circuitry is dull grey, not the boring orange that’s particular of copper.
How to Get rid of a Hot Water Heater
Jeff Gorton, an editor at The Household Handyman, will show you exactly how to remove and also get rid of a water heater in our video tutorial. He will certainly likewise reveal you the easy means to carry a hot water heater out of your home, even if you are functioning alone.
These pointers will make your work go quicker and easier:
Gauge the height of your old water heater and acquire a brand-new one the same elevation so you don’t need to change the size of the water, gas or electrical lines.
The drain shutoff (Photo 2) on old hot water heater frequently congests. If the water drains slowly, hold your horses. CAUTION: It’s scalding hot! TIP: Transform your hot water heater off two hours ahead of time to allow the water to cool down.
Water heaters evaluate regarding 150 lbs. You’ll require a solid assistant or a dolly when you move the old one out and also wheel the brand-new one in. Rubbish solutions usually bill about $25 to take the old one. Innovative Plumbing & Drain
Prior to you begin, buy the devices as well as materials shown right here at a plumbing supply or hardware store or a home facility. Examine the dimensions of the water pipelines (most will be 3/4 in. like the ones in our photos) and get the right-size installations. With every little thing on hand, you’ll require 4 to 6 hours to finish the work (presuming no big hitches!).
The temperature and also pressure relief valve is a security tool that limits container stress as well as keeps it from exploding (Photo 4). A brand-new one should be consisted of with every installation. For the shutoff to function effectively, the discharge pipeline should be maintained free of obstructions (Fig. A).
In areas with very mineralized water, or where needed by neighborhood codes, use 3/4-in. plastic-lined nipple areas (regarding $2 each; Image 5 as well as Fig. A) for joining various metals, usually copper tubing to the steel container. This reduces corrosion.
When connecting the water lines, solder the copper installations before you screw them to the storage tank so you don’t heat the tank itself while soldering (Image 5).
Usage “slip” couplings to connect the old and new lines (Picture 6). Unlike regular combinings, they do not have an inner stop. You can glide them on, line up the copper tubes, then slide them back and center them over the joint.
The brand-new inlets and electrical outlets on the storage tank don’t constantly line up with the old supply lines. Solder in a set of 45-degree installations to offset each line if necessary. Additionally replace the old shutoff valve with a new ball valve while you’re at it (Picture 6). Air vent diameters are sized according to the warm output of the hot water heater. You could need to boost or lower the vent size to make sure the very best draft. CAUTION: If you’re unsure if your chimney has a liner, ask your plumbing inspector. Innovative Pipes & & Drainpipe
Make gas links with solid steel pipe (Photo 8) or soft copper with flare installations (Fig. A). Both are a lot more reputable and also more economical than adaptable stainless steel adapters, which are not always permitted. Use inflexible copper as opposed to versatile copper supply of water lines for the very same reasons.
If you locate your hot water heater substitute where leakage could cause damage to the floor or other parts of your house, established a frying pan of an accepted dimension under it (steel for gas hot water heater). The frying pan should have a drain tube that leads to a home drain or other authorized place (outdoors where permitted). The temperature as well as stress safety valve discharge tube also should result in a drain if leakage would certainly harm the floorings. If directing is difficult, go over alternatives with your neighborhood pipes inspector.
If you live in an earthquake-prone region, strap the water heater to the wall surface with special bands (Fig. A; available at plumbing shops and home facilities). Your plumbing examiner will tell you if they’re called for.
Establish the brand-new water temperature setting to no greater than 120 levels F. to avoid hot.
