Dreading this chore but it was easier than I anticipated. My helper was a 7 year old grandson, a quick learner.
Found my 24" pex hose behind the water heater panel. Only saw one valve to isolate the water heater. There was something that looked like a solenoid on the hot water outlet, I'm assuming it is a blocking valve to keep antifreeze from flowing back into the WH.
No anode rod in the WH, just a nylon plug so I'll add the anode next spring when we de-winterize. The water pump picked up antifreeze and we used nearly 4 gallons. I made sure all the traps had ample antifreeze. The hookup for a washing machine was the most difficult, had to use a hose from each fitting to a bucket to catch fluids.
Thanks to all of you who replied to my questions, you were a great help!
The Brookstone had a bath yesterday and is ready for winter storage. Can't wait until April to take it out again.
Have a great winter folks....
