Feeling Flush

Yesterday was the day to flush. 
   Water heaters to be exact.  Water heaters need to be allowed to drain at least once a year.  That goes for home and RV.  The RV water heater in the RV is easy to drain.  There's an exterior plate that opens to the show the WH.  Near the bottom of the unit is a white plastic plug.  Using a large socket ( 15/16 I think ) the plug is unscrewed.  The water "glug-glugs" out until empty.  Among the water puddle you will see lots of little white specks about the size of rice.  This is why the WH is drained.  The more minerals in the water, the more white specs will accumulate.  The trailer WH had plenty.
After the tank emptied, the plug was screwed back in, being careful not to over-tighten.  plastic plug remember.
    The same goes for the house WH.  It too needs to be drained.  Not as easy.  After watchng several UTube videos, I followed the instructions. 
   Turn off the gas.
   Close the water inlet valve.
   Turn the temperature control to vacation or cool.
   Open a hot water faucet in the house.
   Attach a garden hose to the outlet faucet on the WH.
   Attach a towel or sock to end of the hose to collect debris that flows out. 
   Open the outlet valve to let the water flow out.
   Wait until the flow stops.
   
   No flow !   Yikes !  Another video showed how to remove the faucet if it's clogged.  I didn't want to do that. So I opened the water inlet valve a couple of short bursts and that got things moving.
   Reverse the order to get back to normal.  The interesting part was relighting the WH.  Having to light the oven in the trailer every time we used it was good practice to no big deal.  The pilot light going, it was easy to dial the heating temp setting that we use for everyday.  The surprising part was having to deal with the air bubbles in the hot water line in the house.  After a bunch of spitting and bubbling, things are back to normal.
No debris in the drained water so the once a year frequency is fine.   

Good tasks done.
