water heater question


have a gas water heater. makes a 'popping' sound when it is re-heating water. I assume this is from sediment build up. what is the best way to remove the sediment? hoping someone has some good pointers...

Re: water heater question


Drain the tank and flush it out.

Re: water heater question


It's just a fact of life that the heater is over the hill and is calling for a youngster to take its place.

I've read that heating the water very hot makes draining more successful. Let's think about that for a few seconds. It has a dip tube that goes to near the bottom and if the dip tube is good the water draining becomes cold very quickly. If the water remains hot the dip tube has probably shot craps.

Re: water heater question


You don't need to drain it unless you're moving it, flushing it is enough. That said, if it's several years old and you've never flushed it, you should waive off and leave it alone.

so, what are the steps for just 'flushing' it? We just purchased the house, water heater is pretty new.

Re: water heater question


When you drain it, you stop the incoming water and open the drain at the bottom. Flushing is half the work - you don't shut off the incoming water and let a few gallons out. If the water is murky, keep doing it until the water runs clear.

would you need to shut off the power source? gas?

No, just don't close the incoming water valve.

Cheers!

Re: water heater question


(short answer) No, do not stop the incoming water and open the water tank drain until after you turn off the water heater heat (gas or electric). Otherwise the heater might kick on and self destruct.

Re: water heater question


When a gas water heater (WH) starts making the "popping" sound, it is time to replace it. The "popping" sound is from a layer of sediment in the bottom of the WH, which has solidified into a limestone type rock. You have waited too long to do the required maintenance on your WH. Replace it and remember to drain the sediment out of the new WH at least once a year.

If it's that new, then it's still under warranty and may be a normal sound. Call the manufacture and ask them directly about the noise or look in your owners manual under the troubleshooting section. They should be able to help you further.

Newer energy saver models have heat traps on the top that may cause that issue. Nothing really to worry about. If it turns out to be a heat trap issue, You can replace them with ordinary dielectric nipples available at any big box store.
