Question about Kitchen Ranges

2 Answers

Our house is 6 years old and the "gas" water heater has been recently making a louder than usual humming sound any time that it is "on". Is there something wrong with it or is it normal for the sound to get louder as the heater gets older? The water heater has not been drained in at least 3 years, which I plan to do soon, so I don't know if this could be one reason for the noise.

    Hi - Thx for your reply and recommendation that I look for a new heater.

    In the meantime, I'd like to drain the water heater- can you please provide me with the steps I need to follow to do so?

    Both our water heaters are in two different parts of the attic...can I attach a water hose and let it out right there in the pan that sits under the water heater? (the pan has a pipe that drains outside the house) or should I run a hose all the way out of the house?

It is more than likely the sound of the regulator on the tank,for the gas,you can replace the regulator,or buy another gas water heater,but the regulator is the most likely cause,if the water heater is a 30 gallon tank,then it may be just as affordable to replace it,and easier,and killing two birds with one stone,the heater may be getting some age,and other things could give a problem later,but the cost of the regulator would be cheaper,you will more than likely have to order the part.

The sound you are hearing is the most likely the heating elements, they are old and building up resistance more than they should.

Six years old...and not drained for 3 years...I would recommend looking for a new heater.

I have a Reliance 501 HWH, 15 yrs old. Nary a problem until now. Yesterday, HW was very hot. Today, no HW. I'm thinking of replacing both elements and thermostats due to the age. Sound reasonable?


At fifteen years of age it would be less cost over time and labor to replace the whole tank. How efficient is your old one and being it runs hot all the time you could have a tank that will not last very long anyway. Mine sprung a leak at 18 years and made a big mess.

"Infinity 20" probably 8yrs old now. Recently started making a humming noise whilst in use. The noise continues 15secs or so after hot water tap has been turned off.


Sounds like the diaphram in the gas control valve which is not replacable. You would have to replace the gas control valve and I would also suggest replacing the thermocouple. However since the heater is 8 years old you may think about replacing the entire hot water heater. Depending on how much water has gone through it in these past 8 years it will probably rust out soon and then you will be dealing with a flood.

Good luck,

Marty

Squeeling sound and lower pressure from gas water heater


Probably the factory-installed heat trap nipples are clogged.
Open following links.
http://waterheatertimer.org/Low-hot-water-pressure.html
http://waterheatertimer.org/Low-hot-water-pressure.html#trap
Noisy whistling and humming and low pressure are common problem with heat trap nipples and inserts from factory.
Replace heat-trap nipples with pex-lined nipples, or remove heat trap inserts with screwdriver or needle nose... careful not to break insert so it falls into tank ... which can then get lodged in hot water line elbow or under-sink shut off.
Factory-installed heat traps are part of overall strategy so manufactures can claim more efficient water heaters, without requiring customers to any thinking.
Other strategies include foam insulation instead of fiberglass (so that wires cannot be replaced on electric units), reducing factory-set temperature from previous 130-135 to 100-120, and re-estimating downward the hot water use for average family.
So some of the strategies are useful, while others problematic or imaginary.
Call manufacturer to pay-for or provide new pex-line nipples. Warranty for fist year covers Labor and parts, and after 1st year, warranty covers parts

I have a Rheemglas 50 gal electric water heater. It is 6 years old. It has always worked fine without any issues. I recently drained it and refilled it. I notice from time to time that water is draining...


Hello, It sounds like your T & P relief valve is leaking and needs to be replaced. Over the years, corrosion prevents the valve from sealing properly if it's been opened. It is usually threaded into the top or upper side of the water heater with a pvc pipe attached to it for drainage. If you want to replace this valve, you can buy it at any hardware or home improvement store. Turn off the cold water shutoff valve on the top of the water heater and open the lever on the T & P valve to let it drain out the water. When the water level reaches below the T & P valve, it will stop draining. Then disassemble the pvc pipe if it's threaded, or if it's glued, cut off a section or fitting and replace it with a new one when you reassemble it. Use teflon tape to seal the threads on the new T & P valve. Wrap it around the threads 3-4 times in a clockwise direction with the threads pointed at you. To remove the T & P valve, you can use a 3/4" x 6" black iron or galvanized nipple as a leverage tool to untwist the valve from the water heater. Turn the cold water back on and make sure your thread seal is holding before filling it up all the way. Good luck! Douglas

Neighbor's kerosene tank makes horrible noise at night


The oil lines that run from tank to furnace is acting like a guitar string. As oil is being pumped through the pipe, it is humming. Try placing an old rug on the tank to see if it absorbs the hum.

Can't regulate water temperature


Slower the flow hotter the water is how it works . Sounds like the water section is blocked and could well need cleaning out . Draw back with this system is you need a good inlet flow and flow will drop when you open other taps . they are good for a small house a family house not that good . Not much you can do put in a bigger water inlet to heater ?

A humming sound is coming from my gas water heater.


It is probable a lime build up in the bottom of the water heater tank. You can remove the bottom heating element and clean the lime out, keep in mind this sometimes turns into quite a job though. And you may damage the heating element during removal and have to purchase a new element.
