How many valves did you install? Did you do a valve by the kitchen sink and another by the shower since (at least on the 179) one valve would not be able to serve both areas. Have the motorized valves worked out better than solenoid valves would have? Are they reliable?

two valves. one at water heater and one at the rear kitchen to allow a complete mix of hot/cold. so far the motorized valves are great. i like them better because they only power when switching and minimal power use to stay open and none when closed. so in my 182g, the cold line from main to sink and main to shower would get minimal recirculation, but are enclosed and in heated spaces. i figured the rear kitchen water supply was vulnerable to freezing since it is not in a heated part of trailer and adjacent to a semi exterior wall. from Feb 6th 2019 post the valve for recirculating hot water using the on board water pump
is pictured. The top valve is a normal closed valve that will be
linked to an identical valve (not shown) at the rear of the pod at the
rear kitchen. these two valves are controlled via a thermostat to open
when temps are near freezing and remain closed when temps are not close
to freezing. the valves draw 30ma each to remain open, so they low
energy and should be suitable for boondocking in colder weather. The
valve at the rear will be the mixing valve for the hot water to return
via the cold water lines and dump into the fresh water tank via the
overflow line when both valves are open and the third valve is closed
(the valve at the bottom of the pic.). The valve at the
bottom is a two wire reverse polarity ball valve that will be controlled
by a DPDT switch mounted with the rest of the pod switches by the
stereo panel. This valve controls whether the fresh water flows
normally (as in warm weather with cold/hot mixing at the point of use)
or stops the cold water and then the other thermostatically controlled
switches react to the temperature to open and close to circulate water
to prevent freezing. This valve only uses power when opening or
closing. Once it reaches each state, it uses no power. the idea is to
automate the cold weather function as best i can and be able to return
to the normal configuration with ease. Some of the valves are not easy
to get to. And, i still like the idea of having separate cold and hot
water available when needed. I used pex fittings which
are easy, but are not cheap. They are nice in the tight settings that
this has to be placed since they are simply push to connect. more pics
to come. |
