Getting Started Setting Up Your New Hot Water Tank
We’re replacing a gas water heater in our presentation. The actions for replacing a lp water heater are precisely the exact same, and also those for an electric water heater are similar.
Regardless, when you’re intending a water heater substitute, play it risk-free. Call your neighborhood department of assessments as well as ask if you need a permit. And also make certain a plumbing or electrical examiner checks your job.
Setup Costs and also Labor
Plumbing technicians normally charge $45 to $65 a hr and can typically mount a water heater in a day or in 6-8 hrs.
The majority of property water heaters set you back $150 to $400 for either gas or electrical, plus $200 to $450 if you have a plumber mount it. More costly gas hot water heater with special airing vent systems likewise are offered. However they’re more difficult to install, and we will not handle them here.

When to obtain a new water heater
Your hot water heater is dead when the tank leaks. The indicator that your water heater needs replacing is a sluggish drip below, generally turning up as a route of corroded water. This indicates that the steel tank has actually rusted with and can not be repaired. Other signs, such as inadequate or no hot water, normally signal other water heater fixing issues that you can repair.
If you identify a drip, strategy to change the hot water heater right away. Do not wait until the leak gets negative.
Brand-new water heaters come with setup directions and also lots of warnings to ensure you manage the gas, electric and also other links securely. In this article, we’ll supplement those essentials with methods and also “real world” recommendations from a number of professional plumbers.
However take heed: You’ll be dealing with gas, propane or electrical energy, every one of which are hazardous. If you don’t feel confident, employ a professional to look after the challenging components. As well as have your work evaluated when it’s done.
Plumbing codes vary by area. Explain your planned installation to your regional plumbing inspector, including the types of materials you mean to utilize for your new links. Much better to get advice initially so you don’t need to transform points later on!

Figure B: Links for Steel as well as Plastic Pipeline
Numerous homes have actually galvanized steel or plastic (CPVC) water pipelines. Galvanized steel pipelines are hard to change. We advise that you get rid of the pipelines back to the closest tee, screw on a plastic-lined galvanized nipple area and also finish the links with copper as shown in our picture collection.
Because of possible warmth accumulation, maintain plastic pipeline a minimum of 6 in. far from the air vent as well as tank. Make a shift from plastic to copper with a special combining that’s available anywhere CPVC is offered.
Versatile copper connectors are simpler to install than strong copper, particularly when the existing pipes and the tank inlets do not align. But not all neighborhood codes permit them. If yours does, take unique care not to pinch or kink them. You can obtain a leakage.

Job step-by-step (12 )
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 deal with must go to an appropriate angle to the pipe. Turn off the main water also and drain pipes the lines by opening a faucet on the most affordable flooring.
Drain pipes the water in the storage tank
Attach a garden hose pipe to the drainpipe shutoff as well as drain pipes the water left in the container. Caution: The water will be scalding hot! Disconnect the gas line at the close-by union with a pair of wrenches and also unscrew the pipeline from the gas control valve with a monkey wrench.
Cut off the water lines
Loosen the air vent pipeline from the air vent hood and also relocate to the side. Then reduce the hot and cold water lines with a tube cutter. (Unscrew unions for galvanized pipeline or the nuts on adaptable ports if you have them.) Glide the old water heater off the beaten track.
Connect the relief valve
Cover the strings of the new temperature and also stress relief valve with Teflon tape (3 turns). Screw it firmly right into the storage tank with a pipe wrench. Affix a copper discharge pipe (see Fig. A for transmitting details).
Affix pipe settings up
Solder brand-new copper adapters to 6-in. sizes of 3/4-in. copper and screw the settings up right into the hot water electrical outlet as well as cold water inlet ports in the top of the container. Include short, plastic lined nipples to protect versus galvanic rust, particularly if you have hard water or if they’re needed by regional codes.
Attach the water lines
Move the brand-new hot water heater into location, recut or prolong the old tubing to meet the brand-new, as well as solder the tubing together utilizing copper slip combinings. If the tubing does not line up, offset the lines as required with sets of 45-degree elbows.
Reattach the vent
Reconnect the air vent. Shove it tightly over the draft hood as well as slow with three 3/8-in. No. 6 sheet metal screws. Predrill the openings. The vent should increase a minimum of 12 in. vertically before transforming at the very first elbow joint.
Use two wrenches to connect the gas line
Reconnect the gas line. Cover the threaded ends with pipeline joint substance and also screw the very first nipple area right into the gas valve. Use two pipe wrenches to prevent worrying the valve. Rebuild the continuing to be nipples, finishing up with the union (Photo 2). After that comply with these four steps to load the storage tank: (1) Shut the drainpipe shutoff; (2) turn the water back on at the primary shutoff and open the cold water valve to the hot water heater (leave it open); (3) turn on a neighboring warm water tap up until water appears; and (4) evaluate all the joints as well as installations for water leaks.
Check for backdrafting
Many hot water heater rely on an all-natural draft to draw burning fumes up the flue. If the draft does not work, those fumes, perhaps including dangerous carbon monoxide gas, will spill out right into your house. After finishing your installment, examine the draft.
Close all outside doors and windows as well as turn on your bathroom and kitchen exhaust fans. Then open a nearby warm water tap until you hear the burner in the hot water heater ignite. After a min, relocate a smoking match around the side of the draft hood (Picture 7) in addition to the heater. The smoke must be drawn up the vent pipe. If the smoke doesn’t attract, the fumes from the heater aren’t airing vent. Shut off the gas to the hot water heater and also call a qualified plumbing technician to correct the problem.
Look for leaks
Seek bubbles at links
Activate the gas as well as examine connections for leaks by cleaning a 50-50 blend of dishwashing fluid and also water over the joints. If the mix bubbles, you have a leakage. Tighten up or reconnect joints that leakage. Clean the joints dry when ended up. Call the pipes inspector to check over your job. Comply with the how-to recommendations that goes along with the images to make certain the connections are tight.
Light the pilot light
Use a lighter to light the pilot burner
Light the pilot light according to the manufacturer’s instructions. (For electric water heaters, turn the power on at the main panel after the electrical inspector checks your job.) Ultimately, set the temperature level to 120 degrees F., adhering to the installation guidelines. Light the pilot light in the new water heater and also change the temperature level setup. Innovative Plumbing & Drain
Installation Information for Electric Water Heaters
First switch off the power to the water heater at your major electric panel. After that comply with the same draining pipes procedures as for a gas water heater.
When the water heater is drained pipes, detach the electric cables from the screw terminals under the access panel, which is usually found near the top. (If you don’t have electric experience, work with an electrician to manage all the electric circuitry.)
Adhere to the producer’s instructions for wiring the new water heater. If the brand-new hot water heater is much shorter and also the old cables will not 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 cords to the box, and afterwards run a new area of armored wire or electrical avenue to the water heater. Inspect the directions as well as ensure the score of the old fuse or circuit breaker is high sufficient to deal with the new water heater. Furthermore, the circuit must have a shutoff switch within sight of the hot water heater.
Call your regional electric inspector before you start the task. You’ll probably need a license. Then, when you’re ended up, have the electric examiner examine your job.

Exactly how to Deal with a Hot Water Heater
Jeff Gorton, an editor at The Household Handyman, will certainly reveal you exactly how to eliminate and also dispose of a water heater in our video tutorial. He will also show you the very easy method to lug a hot water heater out of your house, also if you are functioning alone.
These suggestions will make your job go quicker as well as easier:
Gauge the height of your old water heater and also buy a brand-new one the exact same elevation so you don’t have to transform the size of the water, gas or electric lines.
The drainpipe valve (Image 2) on old hot water heater often blocks. If the water drains gradually, hold your horses. CAUTION: It’s scalding warm! SUGGESTION: Transform your water heater off two hours beforehand to allow the water to cool down.
Hot water heater consider regarding 150 lbs. You’ll require a strong helper or a dolly when you move the old one out as well as wheel the new one in. Rubbish solutions typically bill concerning $25 to take the old one. Innovative Plumbing & Drain
Prior to you start, purchase the tools and also materials revealed right here at a plumbing supply or equipment shop or a home center. Inspect the sizes of the supply of water pipes (most will certainly be 3/4 in. like the ones in our photos) as well as buy the right-size fittings. With every little thing handy, you’ll need four to six hours to finish the job (thinking no big hitches!).
The temperature level and pressure relief valve is a security gadget that limits storage tank pressure and also keeps it from blowing up (Picture 4). A brand-new one have to be consisted of with every installment. For the shutoff to function correctly, the discharge pipe need to be maintained devoid of obstructions (Fig. A).
In areas with highly mineralized water, or where required by local codes, make use of 3/4-in. plastic-lined nipple areas (concerning $2 each; Photo 5 and also Fig. A) for joining various steels, normally copper tubing to the steel tank. This slows down corrosion.
When connecting the water lines, solder the copper installations before you screw them to the tank so you don’t heat the storage tank itself while soldering (Picture 5).
Usage “slip” combinings to link the old and new lines (Image 6). Unlike regular couplings, they don’t have an internal quit. You can slide them on, align the copper tubing, then glide them back and also focus them over the joint.
The brand-new inlets and also outlets on the container do not constantly associate the old supply lines. Solder in a pair of 45-degree installations to balance out each line if essential. Also change the old shutoff valve with a brand-new ball valve while you’re at it (Photo 6). Air vent sizes are sized according to the heat result of the hot water heater. You may need to enhance or lower the vent size to make sure the very best draft. CAUTION: If you’re unclear if your chimney has a lining, ask your pipes assessor. Innovative Pipes & & Drainpipe
Make gas connections with solid steel pipe (Image 8) or soft copper with flare installations (Fig. A). Both are more trustworthy and also more economical than adaptable stainless steel connectors, which are not always permitted. Usage inflexible copper rather than versatile copper water lines for the exact same factors.
If you situate your water heater replacement where leak can cause damage to the floor or various other parts of your home, set a pan of an approved size under it (metal for gas water heaters). The frying pan must have a drain tube that brings about a house drainpipe or other authorized location (outdoors where allowed). The temperature and pressure relief valve discharge tube also must cause a drain if leakage would damage the floorings. If transmitting is difficult, go over options with your regional pipes examiner.
If you reside in an earthquake-prone region, strap the water heater to the wall surface with unique straps (Fig. A; available at pipes shops as well as residence facilities). Your pipes assessor will inform you if they’re needed.
Establish the brand-new water temperature level readying to no more than 120 degrees F. to prevent hot.
