    It's on a well. It does not have an expansion tank. There was not one installed on the original system back in 2001 and the plumber did not even mention installing one for the replacement in 2012.
    Sorry, I wasn't completely clear in my original post. Seems like every time the burner turns on I get the thumping noise but it only recently started happening. I'm would have thought it would have thumped from day one if it was due to expansion. It does have a plastic drain valve and if I remember I purchased it from Lowes. Thanks for the help.

    No. The original WH failed in 2012 (bottom rusted out). It was replaced in 2012 with the current system. So now 8 years old. This is the one that is now thumping. Still produces hot water, but I wonder if I am now living on borrowed time.

    Is Rheem or Bradford White still the recommended brands? Thanks.

    Sorry that I misread your info..... 8 years is not all that old but the lime build up in the unit is
    making it bang and carry on... I never have any luck getting those things to quiet down once they
    come alive ... you can flush it till you are blue in the face and it wont help for long..
    its a battle not worth fighting..

    If you have nothing but time on your hands you can totally drain down the heater, then throw 3 or 4 gallons of
    vinegar into the top of the unit through either the t+ P outlet or hot or cold inlets...
    Let the vinegar sit all day long or all night long and it should dissolve the mineral build up....
    Flush it all out and fill it back up... you are gonna take a few baths that smell like salad dressing but
    "in Theory" it should solve the problem.... NO PROMISES HERE....

    I have even heard of folks throwing in CLR to really clean out the lime but it really has to be flushed out well.....

    I will NEVER do this for anybody--- I have heard about it before but I think you got to be nuts-- its too time consuming and
    how do I charge for my time and effort.??? .. This dont always work....
    this is strictly a DIY project

    I would just change out the heater if it is driving you nuts

    Bought a Whirlpool water heater about 18 months ago. Had it professionally installed. The water heater quit heating. Called customer service. Explained the problem. Customer service acted like they had no idea what part I actually needed. Got the parts. Plumber said good luck with that, after installing the burner assembly. Water heated up once, and after 5 days without hot water and a $160.00 repair bill, the pilot won't keep the flame burning. Couldn't believe it. That's why I've decided to buy myself a tankless water heater because it was very well-written and contain a lot of important information needed when you decide to purchase something like that.

    good luck with that tankless path....... the parts on a tankless are far more complicated and harder to
    repair than a simple water heater.. and can be worse than fooling with the whirlpool heater....

    Might I suggest getting a Rheem hot water heater and living happily ever after???

    This has been an informative thread. So I bought my Whirlpool water heater in about 2005. I knew nothing about the problems discussed here until now. Now, the pilot goes out after the burner turns off. I expect I just need to replace the thermocouple, but no one appear to sell TCs compatible with this model, perhaps because of the issues discussed here. Does any one know where to buy one.
    It appears that these are no longer available but there is a new burner assembly with a converter that allows the left-hand threaded TC port in the controller to accept the RH threaded new TC in the kit. I was quoted $39.99 for the kit. Seems like this is the only way forward aside from replacing the heater. Comments welcome.

    Water heaters tend to last between 7 and 15 years. A few will last longer. How much money and time would you like to invest in a product that could fail tomorrow. With no guarantee, no matter how much you spend, that is will last one more day? It's a gamble that plumbers don't like to take, because, we cant make it last longer either. At some point, the welds on the tank are going to give out. If you don't mind the flooding, it might be entertaining.

    Just like Terry said above.... you got 16 years out of that piece of junk which is very , very good considering how many folks could not get 2 years out of one..... and their are many who threw hundreds of dollars towards repairs all in vain...

    Basically you are wiser to get a new water heater and throw that one out.....
    unless you are somehow emotionally attached to the whirlpool water
    heater I would not throw a dime into repairs...
    its like giving someone 100 years old a triple bypass and spending a fortune on
    the operation..... so how many more years is the old fart gonna last????

    Just put it down like you would an old dog, because you are
    the only one that is gonna suffer if you don't.
