Hot water and water heater

rasbury

I recently replaced the faucet behind the helm seat which I don't belive caused my problem but mention it because it was replaced. It only has cold water. Or it used to. So I was out on the water after replacing it, don't recall why I turned it on but it was like boiling hot water.  I did not try any of the others.  Now that faucet barley has any washer pressure while all the rest work fine. I've never messed with the hot water heater but I see there are hoses that I guess circulate engine hot water to support hot water when not at dock? If the heater is internally falling apart internally can that super hot water make it into the system? I'm a little upset that i spent 70 bucks for that faucet that worked perfectly and now does not. I drained the heater from the valve here at home and water drained out- I guess I need to get it running and see but I'm not understanding at all what is happening...any thoughts?

If your water heater is rotted out inside then yes, the raw water circulating will pressurize your water system and it could back flow to the cold side of a faucet.

Oh great...so that goes on the list.  I assumed tgat was happening @YYZRC- I'm guessing the water was hot enough to mess up that faucet? Bummer! I'll get the info off the hot water heater and get one coming...

Unscrew and check the screen on the faucet, it could be clogged.

I got the kuuma 6 gallon for sub 400 bucks about two seasons ago.  Our Bayliner came to us dead with a bad heating element but was kept in place to hold extra water capacity. 

Eventually the rust had everything smelling like pennies if you accidentally turned the hot water faucet on.  

Install was easy.  Installed with the push/pull disconnects to easily bypass the water heater for winterization.

Ras, does your motors have heat exchangers?  (is it closed cooling)  If yes, then it would be antifreeze that would be heating your water, so no leaking there.  I doubt the hot water messed up the faucet.  I agree with Aero that it is probably the screen on the tip of the faucet.

I guess I did not check that as i just installed it, and I will certainly check that.  I thought being a cold water only faucet it was built different than a hot somehow- thanks I will check. While that might a solve the issue, what would be the explanation for scalding water shooting out of that faucet? I am closed cooling..

Definitely check the little screen on the faucet output.  I chased a weak faucet on my RV, which ended up being a .79 cent screen that was clogged
