    I have not yet installed the control valve, but the service, through purchase and delivery as been exceptional. Shipment was rapid. A smooth purchase/payment, and the valve is ‘in hand’. It will be installed soon, and I do not anticipate any difficulty.

    Pilot light would not stay lit. This part was replaced and so far it’s kept my water heater working.

    I haven’t attempted to install the part yet, but it’s got a big scratch on the front above the status light and almost looks like it’s refurbished or has been used before.
