I have been a plumber for twenty-seven years. I have been known as by home owners at all several hours of the evening for, broken drinking water lines spewing crystal obvious h2o almost everywhere creating its beautiful existence identified to carpet, seemingly to say, “I’m right here to ruin you, or, “I am heading to drench you, and fade your pretty colour.” I have been known as out to gorgeous residences with sewage in every single corner of the house, producing it seem like a barn fairly than a mansion. Practically nothing is much more annoying than likely to a house wherever the drinking water heater is torn apart, and the property owner is complaining that he ought to have very hot drinking water prior to early morning, or he will absolutely die. I’ve needed to say, so many situations, “if you wouldn’t have touched it, and just left it alone, then it would have been great right up until early morning.” Had I stated one thing like that, he would have been on the cellphone to my boss, and I can listen to him now, “That’s your task. You are on get in touch with. If you don’t want to do the work, I’ll uncover somebody who will.” So I bite the bullet, and speak great to the property wrecker, I mean home owner, while doing work on his screw up. Right after awhile I forget all about my irritation with him.
Anyway, enough explained about why I’ve had to change h2o heaters in the center of the night time. I may be in a position to shed some light on the correct mode of installation in this column, which I so diligently publish to evince a diverse plumbing problem every single week.
One particular point about plumbing is that every single work ought to be carried out in a step-by-stage way, specially h2o heaters. When you’ve identified that the leak is without a doubt, from the tank…
one. Shut off the drinking water to the appliance.
According to the Uniform Plumbing Code. (The Plumber’s bible.) There is meant to be a shut off, not a lot more than two feet from the drinking water heater on the inlet, or cold side of the appliance. It will most most likely be a “wheel valve.” It ought to flip to the appropriate to flip off the water, and it must turn to the left to flip on the drinking water. Flip this valve to the proper, until finally it won’t turn anymore. The water should be off to the h2o heater. You will nevertheless have cold h2o in the residence to all the fixtures. I advocate you really don’t use the cold water until the installation is total, because you will get a back again- feeding of h2o out of the pipes you disconnected from the water heater. If the house is really aged, or the authentic plumber didn’t adhere to the U.P.Do. a shutoff may possibly not have been incorporated for the water heater. If you encounter this circumstance, you’ll need to have to shut off the water to the total home at the principal shutoff, which is typically positioned in the front of the property, on the wall outside. This act of necessity is not normally a problem for an experienced plumber, but can be a scary encounter for a property owner, or newbie repairman, due to the fact soon after you are completed replacing the drinking water heater, and you can not turn the drinking water back again on since of a leak or an additional unexpected issue. Wives, girlfriends, or children are inclined to get irate when they don’t have any drinking water for showers or cooking. Also, it can practically wreck a marriage when you have to call a plumber at two in the morning on a Sunday, and pay out him or her $two,five hundred.00 for an emergency get in touch with, after you have worked on it all day.
two. Drain the drinking water heater.
Track down the drain valve at the bottom of the h2o heater. It appears like an exterior faucet, and you almost certainly have two or 3 of them close to your house at diverse areas. Screw your garden hose to the drain valve, and pull it exterior to a area exactly where you can permit water drain. The drinking water won’t hurt the grass.
At times these drain valves are clogged with sediment, and require to be cleared so the w/h will drain in a timely way. (A wire coat hanger performs properly.) Subsequent, find the temperature stress relief valve at the best of the water heater, (also essential by the code) and open up it manually. (Some individuals get in touch with these the pop off valve) This will force air into the drinking water heater and let it to drain. The cause I do this is the exact same principle as holding your thumb on a straw, with h2o in it. The drinking water stays there. When you get your thumb off, the drinking water drains out. Open this valve and start off the heater draining.
3. Disconnect the previous h2o heater.
Identify the unions on the sizzling (outlet) and cold (inlet) lines to the w/h. (Also essential by the UPC, not much more than twelve inches from the appliance.) Undo the unions with two pipe wrenches. Shut off the gasoline valve on the left side, at the bottom of the water heater, and disconnect that union too. Disconnect the vent, by unscrewing the 3 sheet steel screws from the draft diverter dead center on top of the waterheater. The h2o heater is completely disconnected, and you can proceed to the up coming action.
four. Prep new h2o heater for set up.
It is time to get the new drinking water heater prepared to install, in the spot of the previous water heater. I always use a ¾” x3 in. brass nipple, with a brass ball valve screwed onto it for the cold facet. (Remember, the cold facet is the inlet, where the shutoff is supposed to be.) By getting brass screwed into the metal tank of the drinking water heater, I’m avoiding electrolysis. Electrolysis occurs whenever copper is screwed into steel. It will tremendously speed up the corrosion approach, and the pipe will very last about 1 3rd of the time, if you use dissimilar metals. Up coming, I screw a brass nipple into the hot side of the h2o heater, with a brief piece of pipe, and include unions to each sides. Any residence that is older than eight years or so, is most likely copper, and will require to be soldered. The pipe and unions connecting the hot, and cold aspect of the water heater, will have to be cleaned with a piece of sand cloth manufactured with aluminum oxide, and fluxed with a brand name flux, to make certain the solder normally requires effectively in the joints. Make confident the unions are at the exact same height from the best of the drinking water heater, and solder every thing. Also install a pipe from the new temp. and pressure relief valve to specifically six inches from the flooring. (Also needed by the Uniform Plumbing Code.) This completes the water hook up.
There needs to be a drip leg on the gasoline hook up to catch moisture, and sediment, as not to clog the pilot and burners. Set up a new gas shut off, and reconnect the fuel line to the fuel handle, on the left aspect of the appliance. Then make certain the vent pipe is the appropriate measurement in diameter for the B.T.U. rating of the new heater, and connect it to the new draft diverter. Make certain you use three sheet metal screws, in each joint of the vent. Generate them in with a screw gun.
5. Flip the drinking water on.
Turn the h2o on soon after you have opened the sizzling facet of the faucet only, on the bathtub. It is greatest to open the 1 farthest absent from the h2o heater, to bleed the air out, and assist in a quicker fills up. Also repeat the step that you did earlier, by opening the temperature, strain relief valve, until you hear the h2o nearly to the leading of the heater. At initial only air will come out. Once the drinking water is flushed out good in the tub, close the tub faucet, and check the drinking water heater place for leaks. Open up the gas valve, and check out for leaks at the gasoline line.
6. Light the pilot
When lights the pilot use a lengthy match, because most folks cannot get their hand in the tiny firebox. If you can, you are going to most likely reduce your hand when you pull it out.
Push down the red button, whilst the knob is on pilot, and light the pilot. Hold the button down for about 30 seconds or so. When you allow the red button go, the pilot really should remain lit. Flip the knob to the “on” position, and turn up the thermostat, to the placement that is marked, “standard.” The flame on the burner should arrive on with a woosh! Do not be afraid, due to the fact this is standard. Inspect the flame from the burner. It must be a good yellow shade, with blue suggestions on the flame. Clean up the location, in front of the drinking water heater.
The last point I ought to mention is that you will hear a drip, drip, drip audio, that you right away believe is a leak. Don’t be alarmed! It is condensation from heating up forty gallons of cold h2o all at as soon as. It will cease in about thirty minutes.
A new water heater has arrive out, and in accordance to code, by September 4, 2007 the h2o heaters will be distinct with a sealed combustion chamber. These new ones will light by just pushing a button, and are a lot safer. You do not even require to elevate them over the garage floor 18″ like used to be the code.
I hope it will be easier for you to change that h2o heater when it commences leaking. Just don’t forget though, don’t panic. Place a towel about the aged, leaking water heater, and wait right up until the up coming morning to tackle the activity.
