Look around valves, put your hand on one, carefully for temp..., and see if you can determine the source. What happens is the rubber seats eventually start to fail and become loose. They can chatter on water flow.

Refrigerator has developed a low buzz or hum. Do I need to be concerned?


Hello friend, thank you for your post!

I understand that your Frigidaire refrigerator, LFHT1817LW1, is buzzing or humming. With modern, high efficiency compressors you may hear a high pitched humming or pulsating sound. Additionally, if you have an icemaker equipped inside of your refrigerator the water valve may produce a buzzing noise as the valve opens to fill the icemaker with water. I hope this has been helpful. -Matt

Random banging and whooshing sound


New water heater?
http://waterheatertimer.org/New-water-heater-making-noise.html
http://waterheatertimer.org/Repair-water-heater-valve.html
Water does not compress. So each faucet has air chamber located behind wall. Air chamber is usually just a vertical piece of pipe about 18" long with a cap so it never fills with water. When water flows... all the water back to the main supply begins to move toward the faucet. The weight of this water can be considerable. When faucet is turned off, the whole column of water suddenly stops, but weight of water is still pushing forward.
Without air chambers to cushion the sudden stop of water weight, the pipes bang and rattle. With air chambers, the weight of the water pushes up into the air chamber causing the air to compress, which silently cushions the weight of water, but also causes a push-back when water stops moving forward. The push back can then move water backwards where it compresses air inside another air chamber. So the water can slosh back and forth.
IF you have factory-installed heat traps on your water heater, these things have rubber baffles. The baffles hum and rattle and whistle and clog and cause strange sounds that carry through the pipes and water heater and wood joists etc. The water sloshing back and forth can move the baffles and cause noise.
Or maybe you have a check valve that has gotten loose.

I would have to go along with your brother on this one. The aluminum anode rod is by far the cheapest way to go. Other options include extensive filtration,ozone treatment and acid treatment.
The aluminum anode rod is much cheaper and I would recommend you change it yearly at least. Good luck and thank you.

Grundfos recirculating system. Never has produced semi instant hot water at sink it is installed on. Could the original comfort valve be defective


http://waterheatertimer.org/Water-heater-recirculation-system.html

The circulation system should draw hot water directly from the water heater as shown on illustrations on link above.

The Grundfos pump works on a thermostat, and some work on a timer.
Can you hear the pump working?
There should be a humming sound.
Check the timer -or- thermostat setting.

It is possible the lines are clogged with sediment if you have hard water.

If I was going to fix the problem:
1) check thermostat or timer
2) listen for pump sound
3) check electricity going to unit
4) take apart the pipes and inspect for clogging
If there is a clog, I would flush the line or soak the part in CLR (calcium lime rust remover)

The circulation pumps are sealed and there is no way to take apart the motor, timer, or thermostat for repairs.

add a comment if you need more assistance.

MY UNDER FLOOR HEATING IS WORKING , BUT ALL OF A SUDDEN THE ROOMS HAVE ALL GONE COLD AND THE HOT WATER ONLY RUNS HOT FOR ABOUT TEN SECONDS HELP!!!


Hi, It sounds to me that you have a floor furnace that is working, but you have hot water set-up for the rest of the house. You say the water stays hot for about 10 minutes only? Is it on a hot water heater or small boiler with a circulating pump? If this is how it is set up, It sounds as though what ever is heating the water to the rest of the house is shutting off to soon, or if you have a pump, it may have failed. If you do have a pump that has failed, they are set - up to shut the heating system down if it were to fail. Please check to see what set-up you have and get back to me asap, so that I can solve this for you. Check these things out I have Mentioned to you and let me know.
Sincerely,
Shastalaker7

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.
