When to get a brand-new water heater
Your hot water heater is dead when the storage tank leaks. The indication that your water heater requires replacing is a slow-moving drip below, normally showing up as a path of rusty water. This suggests that the steel container has actually rusted through as well as can not be repaired. Various other signs and symptoms, such as inadequate or no warm water, generally signal other hot water heater repair issues that you can deal with.
If you detect a drip, strategy to replace the water heater today. Do not wait until the leakage obtains bad.
New hot water heater include installation directions and also lots of cautions to make certain you take care of the gas, electrical and also various other links securely. In this post, we’ll supplement those essentials with methods as well as “real life” suggestions from several specialist plumbing professionals.
Yet beware: You’ll be dealing with gas, gas or electrical power, every one of which are dangerous. If you don’t feel confident, call in a professional to take care of the hard parts. And have your job examined when it’s done.
Pipes codes differ by area. Describe your prepared installment to your neighborhood plumbing examiner, consisting of the kinds of materials you mean to use for your new links. Better to get advice initially so you don’t have to alter points later on!

Number B: Links for Steel and Plastic Pipeline
FAMILY MEMBERS HANDYMAN
Many homes have actually galvanized steel or plastic (CPVC) water system pipelines. Galvanized steel pipes are challenging to change. We advise that you get rid of the pipes back to the local tee, screw on a plastic-lined galvanized nipple and also finish the links with copper as received our image series.
Due to possible warm build-up, maintain plastic pipeline at least 6 in. away from the air vent and also storage tank. Make a shift from plastic to copper with a special combining that’s readily available anywhere CPVC is marketed.
Flexible copper adapters are much easier to set up than strong copper, specifically when the existing pipes as well as the storage tank inlets don’t align. But not all local codes permit them. If yours does, take unique treatment not to pinch or kink them. You can obtain a leakage.

Shut down the gas as well as water
Switch off the gas to the water heater by turning the neighboring shutoff valve a quarter turn. When off, the take care of should be at an ideal angle to the pipe. Turn off the major water also and drain the lines by opening up a faucet on the most affordable flooring.
Drain the water in the container
Attach a garden 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 nearby union with a pair of wrenches and also unscrew the pipeline from the gas control shutoff with a monkey wrench.
Cut off the water lines
Loosen the vent pipeline from the air vent hood and also 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 adaptable connectors if you have them.) Move the old water heater out of the way.
Connect the relief valve
Cover the threads of the new temperature as well as pressure safety valve with Teflon tape (3 turns). Screw it snugly into the storage tank with a pipe wrench. Attach a copper discharge pipe (see Fig. A for directing details).
Connect pipeline settings up
Solder new copper adapters to 6-in. sizes of 3/4-in. copper and also screw the assemblies into the warm water outlet and also cool water inlet ports in the top of the container. Add short, plastic lined nipple areas to shield versus galvanic rust, especially if you have hard water or if they’re called for by regional codes.
Connect the water lines
Move the brand-new hot water heater right into location, recut or expand the old tubing to meet the new, and solder the tubing with each other making use of copper slip combinings. If the tubes does not line up, offset the lines as required with sets of 45-degree joints.
Reattach the vent
Reconnect the air vent. Push it firmly over the draft hood as well as anchor it with 3 3/8-in. No. 6 sheet metal screws. Predrill the holes. The air vent must increase a minimum of 12 in. vertically before turning at the initial elbow joint.
Usage 2 wrenches to connect the gas line
Reconnect the gas line. Coat the threaded ends with pipeline joint substance and also screw the first nipple right into the gas shutoff. Usage two pipe wrenches to avoid stressing the shutoff. Reconstruct the continuing to be nipples, ending up with the union (Image 2). Then adhere to these 4 actions to fill the container: (1) Close the drain valve; (2) turn the water back on at the major shutoff as well as open the cool water valve to the hot water heater (leave it open); (3) activate a close-by hot water tap till water comes out; and (4) evaluate all the joints and also installations for water leaks.
Check for backdrafting
The majority of hot water heater rely on a natural draft to draw combustion fumes up the flue. If the draft doesn’t work, those fumes, potentially consisting of fatal carbon monoxide, will splash out right into your residence. After completing your installation, check the draft.
Close all exterior windows and doors and also turn on your bathroom and kitchen exhaust fans. After that open a close-by hot water tap till you listen to the burner in the hot water heater stir up. After a minute, move a smoking match around the edge of the draft hood (Image 7) on top of the heater. The smoke should be drawn up the vent pipeline. If the smoke doesn’t draw, the fumes from the heater aren’t venting. Switch off the gas to the hot water heater and call a certified plumbing professional to remedy the problem.
Look for leakages
Seek bubbles at connections
Activate the gas as well as inspect connections for leaks by cleaning a 50-50 mixture of dishwashing fluid and also water over the joints. If the mix bubbles, you have a leakage. Tighten up or reconnect joints that leakage. Wipe the joints dry when ended up. Call the plumbing assessor to check over your work. Comply with the how-to advice that accompanies the pictures to ensure the connections are limited.
Light the pilot burner
Use a lighter to light the pilot burner
Light the pilot light according to the maker’s instructions. (For electrical hot water heater, turn the power on at the primary panel after the electrical inspector checks your work.) Ultimately, established the temperature to 120 degrees F., adhering to the installment directions. Light the pilot light in the new hot water heater as well as readjust the temperature level setup. Innovative Plumbing & Drain
Setup Information for Electric Water Heaters
First turn off the power to the hot water heater at your major electrical panel. After that follow the very same draining procedures when it comes to a gas hot water heater.
When the hot water heater is drained, separate the electrical cables from the screw terminals under the access panel, which is normally found near the top. (If you don’t have electrical experience, employ an electrician to handle all the electrical circuitry.)
Adhere to the supplier’s guidelines for electrical wiring the brand-new water heater. If the brand-new hot water heater is much shorter as well as the old cables will not reach, surface-mount a 4-in. x 4-in. x 1-1/2 in. metal electrical box on the wall or ceiling nearby, run the old wires to package, and then run a brand-new section of armored cable or electric avenue to the hot water heater. Inspect the directions as well as see to it the ranking of the old fuse or circuit breaker is high sufficient to take care of the new hot water heater. On top of that, the circuit ought to have a shutoff button within view of the hot water heater.
Call your neighborhood electric assessor prior to you start the job. You’ll possibly require an authorization. Then, when you’re ended up, have the electric assessor examine your job.
Light weight aluminum wiring needs special handling. If you have aluminum electrical wiring, employ a qualified pro that’s licensed to collaborate with it. This wiring is boring grey, not the dull orange that’s characteristic 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 get rid of as well as get rid of a water heater in our video tutorial. He will certainly additionally reveal you the easy way to carry a hot water heater out of your home, even if you are working alone.
These suggestions will certainly make your job go much faster as well as easier:
Measure the height of your old water heater and also purchase a new one the exact same height so you do not have to change the size of the water, gas or electric lines.
The drainpipe shutoff (Picture 2) on old hot water heater usually clogs up. If the water drains gradually, be patient. CARE: It’s scalding warm! POINTER: Turn your water heater off two hrs beforehand to allow the water to cool.
Water heaters weigh concerning 150 lbs. You’ll need a strong assistant or a dolly when you relocate the old one out and also wheel the brand-new one in. Trash solutions commonly charge about $25 to take the old one. Innovative Plumbing & Drain
Prior to you start, purchase the devices and also products revealed here at a plumbing supply or equipment shop or a home center. Check the dimensions of the water pipelines (most will certainly be 3/4 in. like the ones in our photos) as well as acquire the right-size fittings. With every little thing accessible, you’ll need 4 to six hrs to complete the job (assuming no huge drawbacks!).
The temperature and stress safety valve is a safety and security gadget that restricts storage tank stress as well as keeps it from exploding (Picture 4). A new one must be consisted of with every setup. For the shutoff to function properly, the discharge pipeline should be maintained devoid of obstructions (Fig. A).
In regions with highly mineralized water, or where called for by regional codes, utilize 3/4-in. plastic-lined nipples (concerning $2 each; Photo 5 as well as Fig. A) for joining different metals, typically copper tubing to the steel tank. This reduces corrosion.
When connecting the water lines, solder the copper fittings before you screw them to the container so you don’t warm the container itself while soldering (Photo 5).
Usage “slip” couplings to attach the old as well as new lines (Photo 6). Unlike normal couplings, they don’t have an interior stop. You can move them on, align the copper tubes, then slide them back and also focus them over the joint.
The brand-new inlets and electrical outlets on the tank do not always line up with the old supply lines. Solder in a pair of 45-degree installations to offset each line if needed. Also change the old shutoff valve with a new round valve while you go to it (Photo 6). Vent sizes are sized according to the warm outcome of the water heater. You might have to raise or reduce the air vent dimension to ensure the very best draft. CAUTION: If you’re unsure if your chimney has a lining, ask your plumbing assessor. Cutting-edge Pipes & & Drain
Make gas connections with solid steel pipeline (Picture 8) or soft copper with flare installations (Fig. A). Both are more trusted and cheaper than flexible stainless steel ports, which are not always allowed. Use rigid copper instead of adaptable copper water supply lines for the exact same reasons.
If you find your water heater substitute where leakage might create damages to the floor or other components of the house, set a pan of an accepted size under it (steel for gas hot water heater). The pan must have a drain tube that leads to a house drain or various other accepted location (outdoors where allowed). The temperature level and also pressure safety valve discharge tube additionally need to cause a drain if leakage would certainly harm the floors. If directing is tough, go over choices with your neighborhood plumbing inspector.
If you reside in an earthquake-prone area, band the hot water heater to the wall with special straps (Fig. A; offered at plumbing stores and also residence centers). Your pipes examiner will inform you if they’re required.
Set the new water temperature level readying to no more than 120 levels F. to prevent hot.
