Always learning about the most random things...

In this episode, we learn about hot water heaters.

Water heaters have a temperature and pressure release valve, even its own acronym, T&P valve..... who knew???


Well, apparently a lot of people outside of me, just YouTube (best learning tool ever!) T&P valve.

T&P Valve Replacement

To back up a little bit, we were out sailing a few weeks ago [enter blog post from trip with Rob] when I went below to do my normal 30 minute check and found gallons upon gallons of water in the aft head.  Fortunately our one-design head floor unit kept the water in place and I simply disposed of this by using the shower sump pump.  Curious though, I tasted the water as it looked awful clear and clean.  Sure enough, it didn't taste great but it wasn't salt water.....so where was this coming from.  Turns out our T&P valve went bad.  How you ask, or I asked.....the spring inside for measuring pressure just wears out over time.

Replacing the valve actually isn't that difficult..... riiiiiight (said with sarcasm because we're talking about replacing it on a boat!)



Process is this:  turn off the water heater, turn off incoming water, release pressure and some water by using the T&P valve, unscrew T&P valve, put new one on.  Simple.  Now add boat.

Of course our valve is facing away from me and our water heater is properly secured down with several nuts and bolts, most of which are completely unreachable without removing the mast (jk but that's what it felt like).   Once I got everything removed and replaced then the fun came, get the water heater back to where it started and re-secured.  During this process one of the funniest things to happen since living aboard, but could've been seriously dangerous.  As I was muscling the water heater back into place, the water-out hose popped off and started spraying pressurized water which luckily I properly followed directions and turned the water heater off several hours earlier so the water wasn't scalding hot, but that didn't save me from a blasting and soaking.  Monica ran over but doubled up in laughter before she could hand me a towel, and made sure she found her camera first. So guess what they don't tell you about water heaters on home improvement websites....on a boat you need to turn of the hot water pump as well.....whoops.
