    Exclamation New Indirect Water Tank is Noisy! Anyone know why?

    Just had a new Weil Mclain Ultra 155 gas boiler installed as well as a Weil Mclain 60 Indirect hot water tank. When ever the water in the house or spinklers are being used, there is a rattle inside the tank. When we use the cold water only, it still makes noise.

    Anyone have any ideas? Im thinking this should not be and it may be a defect from the factory. Any info would be greatly appricated.

    Looks like whoever put your system in has a lot of pride in what they do and should be more than happy to come back and find out what's making the noise so that you're 100% happy.
    Use the biggest hammer you like, pounding a square peg into a round hole does not equal a proper fit.

    If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.

    If you do know, then do. But do it right. Otherwise, you may not be doing it long.

    Could be a check valve making the noise.
    Have your installer come back and check.
    How many heating zones do you have.

    Well, the plumber that installed it does not know what it is.

    The supplier who he go it from says its normal. I called Weil Mclain but they are impossible to get a rep on the phone who will call you back....

    2 zones + the indirect

    You have to be a contractor or distributor to get a WM rep on the phone.

    Open up the cold faucet so it makes the noise, take a long screw driver. Plave its blade against the valves and other fittings, with your ear on the handle. When you get to the loudest fitting/device. That where the noise is coming from.

    low water pressure?

    Maybe the hot water is tring to force it's way back out the cold water feed line when
    you open a cold water valvem reducing the pressure. I'd get a flow check on the incomming cold water to the indirect.

    That would be easy to verify by touch before installing a valve that may not solve it.

    Close the valve on the cold water pipe going to teh tank and see if it still does it. If it doesn't, then you need a check valve like John said.
