There is air in the sytem somewhere, very common. They make a anti bang suppressor for household systems. Try the hardware store and tell them your issue. What it basically is, is a small storage tanks hooked to your system to absorb the banging from the air pockets.

How do I winterize my 2015 Jayco Jay Flight 32 RLs


Go to an RV parts store for a winterizing bypass kit for the water heater. Use POTABLE RV antifreeze and follow the instructions on the bottle. Drain all the water out of the water tank. Install the bypass kit on the water heater if it doesn't already have one. Put the water heater in the bypass mode. Add the antifreeze to the water tank. Open every water faucet including the shower head one at a time until antifreeze is present. Do this for hot and cold on every faucet. Once that is done, turn off the water pump and open all the faucets. That's all there is to it. Rember... DO NOT use automotive antifreeze. It will kill you.

Water Heater Rumbling When Running Cold Water In Faucet


Check and see if the cold water has been plumbed to the 'c' on the heater, the hot to the 'h', and the relief valve somewhere else, usually on the side. Maybe the plumber cheated somewhere to make installation easy.

How to clear Major plumbing clogs


I am assuming that you are referring to a calcium or rust build up in the water heater.
If you are having this issue you will need to turn off the water to the heater. You will need a garden hose, access to a outside water soucre, cold water is fine.
Shut off the gas or power to the hot water heater before starting.
Now you will need to place the garden house on the drain fitting on the water heater, placing the end of the hose outside and lower than the drain valve. Open the valve and drain the heater, you will need to open a hot water faucet to help drain the heater. I don't suggest opening the TPR ( Temp Pressures relief )valve due to the fact that they sometimes leak or don't reseal after opening them.
Hopefully the drain valve is not clogged, you should hear and see water exiting the garden hose.
If you are not getting any water from the drain valve you are going to have a challenging task.
If no water is coming out, my recommendation is to get the required tools to remove the hot water line from the top or side or the heater, also a few towels to soak up water A bucket is helpfull also.
remove the hot water line, then you will have to use a small hose to siphon the water from the tank. Once the tank is empty you can then remove the drain valve and replace it.
once you have replaced the drain valve you should ensure that it's closed and use a Gallon of CLR. Poor this into the water heater through the hot water outlet where you removed the pipe from. Now make sure the faucets are closed and replace the hot water line. You can now turn the water back on to the water heater.
After a few minutes open a hot water faucet to let out any air until water flows out, than close the faucet.
Let the water heater set for a few hours, then drain the tank!
when the tank drains, close the drain valve again and refill the water heater. Once again open a a hot water faucet and let the air out till the water heater fills. Again let sit for a hour.
At this point open a hot water faucet at the farthest point from the heater and let the water run for 5 min. , than close it and move to the next closest faucet and repeat until all faucets have been opened and run for 5 minutes.
If you still have a slow flow in a faucet, you may need to repeat the CLR step.
I also suggest that you remove all faucet screens and clean them.
If you still have a clog than you are going to have to remove or replace a piece of water line in the house. The blockage may be hard to find but if you have access to most of the pipe or it's visable you may be able to hear the blockage with the water on. Otherwise this will result in using some water line taps and a pressure guage to find the blockage.

I have a leak coming from the "cold" line right at the valve joint. There is signifigant calcuim build up on the pipe from the valve to the connection of the water heater, (maybe 8 inch of pipe)...


Very simple - call a Plumber. He will fix your plumbing problem, and any foreseen potential problems related to your water leak. He may also suggest replacing your 6 year old water heater. Of course ..... for a professional cost.
However, depending on your time, skills, proper tools, patience and luck, it's easy enough to perform yourself:
1. Switch off the water heater Breakers (220v) in your service panel.
2. Turn off the water supply to the water heater.
3. Attach a water hose to the drain faucet. ( a good time to flush sediment -calcium deposits)
4. Open a hot water faucet to vent (above the level of the water heater drain - kitchen sink)
5. Remove the suspected leak components. (a union connection is a good place to start)
6. Install New pipes -3 wrap all male threaded ends with teflon Tap. Tighten securely - using 2 wrenches.
NOTE: Before refilling - you can turn on the water heater supply valve for a few minutes, to flush out any lingering calcium debris.
7. Shut off drain valve - remove hose. Shut off venting hot water faucet.
8. Turn on water supply valve to fill water heater.
9. Open a hot water faucet to relieve air pressure while filling - preferably the bath tub faucet, it doesn't have a screen that might clog.
10. When water flows without air - shut off tub faucet.
11. Look for leaks.
12. Switch the water heater Breakers on.
Note: 50 gallons should take an hour or more to heat up. Turn on a hot water valve momentarily within this heat up time to relieve thermal expansion. ( the PT valve on your water heater will perform this task if pressures/temperature exceed new water heater tolerances - it's just a precaution to introduce these fluctuating pressures on your fragile 6 year old unit)

These are just basic instructions - assuming you fill in the common sense and work safe steps.
Good Luck - The Skill will only come after trying.

Popping noise in water heater. What is it and how do I fix it?


What is probably happening is that you have a build up of minerals on inner tank lining and when unit is heat it expands the tank and the deoosits at a different rate which is what is causing the popping noise.
I would turn power off to your heater and hook a garden hose on to drain valve.Route hose to safe area as the water being drained will be hot. Open drain valve and see if you can get it draining good.If it is then shut off water supply to heater and open hot side of faucet nearby to prevent vacumn from slowing down draining. I would drain as much as I could then close drain valve and faucet and refill tank. I would do this several times to try to get all sediment flushed out.Hopefully this will help with your noise and make your heater last longer and work more effceiently. Good luck and thank you.

Kenmore Ultra Wash water supply started making loud noise while water is entering washer. If you turn on sink faucet at the same time the noise will stop.


It sounds like the solenoid valves which let in the water are not fully opening and causing chatter -- probably corroded . Turning the washer-water supply faucets down (to the left) will probably stop it, but the solenoid valves need to be checked.

The reason opening the sink faucet stops the noise is that it reduces the water pressure to the washer -- this is the same effect as turning the washer faucets down.

Water from new water heater smells like sulfur & has air pockets


Sounds like there might be a super-hot spot in the water heater and the water is boiling. Can you hear some percolating noises from within the water heater from time to time?

Cant get my 50 gal rheem electric water heater to drain to change elements


There is 2 ways to do this.
The first way is to turn off the power. Turn off the incoming water (cold) to the heater. Go to a faucet close to the location. Turn off the cold water supply under the sink. Open the hot water side of the faucet. Allow any water to drain from the faucet. Make sure that the water coming out is not under pressure. You should be able to tell by how it come out. Easy, or forceful. Now go to the heater and open the bottom drain valve. The reason it does not drain very easy is because you have a vacuum. Similar to having a soda bottle full of water and turning it upside down. It will drain but it will "Glug" and drain slow. Opening the hot side of the faucet relieves the vacuum and it should drain o.k. When you are done with your repair, leave the hot side of the faucet open and turn on the incoming water to the heater on. Let it fill till you get a steady stream of water from the faucet. This "Burbs" all air out and ensures the tank is full prior to turning on the power. When you get the steady stream, turn off the faucet and restore power. In some cases, the heater may sweat because you are heating very cold water. This is normal and will only happen this one time.
Now if you want to know the second way, let me know. I've done it dozens of times with plenty of success and minimal mess.
Good Luck
