Topic: Low point drains? Posted: 21 Apr 2014 at 10:29pm |
Just curious what is the purpose of the two low point drains? I realize the one on bottom of the fresh water tank is used for emptying.
Are the low point drains used for emptying the water heater?
Thanks.

They drain all your water lines. We open all the faucets and remove the caps. Drain the hot water tank by removing the anode rod plug. Moe

^Exactly. The low point drains are the lowest point in your R-Pod's plumbing.
When winterizing, after you've run antifreeze through your taps, shower and toilet, turn off the pump and open the low point drains to flush out the last of the water. There's some debate over whether you repressurize the lines after resealing the low point drains. I think its a moot point - but I repressurize all the same.

The tanks have drains that empty the tanks. The low point drains are for the water in the pipes. There's one drain for the hot water pipe and one for the cold water pipes. Open all the taps, including the hot and cold shower and the sink and flush the toilet to release the vacuum that would hold any water up after you remove the caps from the low point drains. They let the water out of the everything past the tanks.
They might eventually drain the hot water heater, but as others have said, standard practice is to remove the anode and let the water run out.

An alternative for the water heater is to open the low point drains and then open the overpressure valve (near the top of the water heater, on the outside). It takes about 10 minutes, but it works.

Any downside to doing this versus removing the anode? Is it easier?

I did once unseat the valve and have to fiddle with it for 10 minutes to get it to seat again - it may have just been a fluke, but I'd rather not do that again. But, most of the reason I'd suggest draining by removing the anode is to inspect the anode. Normally, I only winterize and pull the anode once a year - its a great opportunity to check and make sure there's still lots of meat on it.
