    Leaking joint on hot water outlet pipe of unvented water heater

    Hello All, I've got a small leak where the pipe of the hot water outlet of an unvented water heater joins the valve. I'm attaching a couple of photos to give an idea of the set up. Is there a good solution that doesn't involve resoldering the joint? Many thanks.

    Will low water flow affect the function of an electric tankless water heater?

    I have a cabin about 300' from my well and about 30' elevated from the well. The water heater doesn't work properly. The flow is low through the tankless electric water heater. Is it necessary to increase the flow? If so, how am I able to do that?
