In the pics shown at the left beside the grey valve is what looks like a regulator attached to a powered source that is tied into the water pump power Is this unit really required for the water pump to do its job?? I am trying to stream down this are so I can put in longer hoses to reduce noise.
I have since removed the valve and the accumulator
The regulator is built into the pump. If you mean that brass thing I think that is your fill
valve.
Always wanted to know where the fill valve was!
Thanks!
What is that thing that looks like a small liquid/air heat exchanger with a fan?
That is the heat exchanger and fan for the basement heat off the Aqua hot.
So I am going to add this to this post, apart from one other I posted, but, I want to add vinegar to my system including the Aqua hot to clean the system out. When I attached a hose to the reel hose to suck up vinegar and then turn on the water fill I hear a click but the water fill does not suck up the vinegar out of the gallon jug. Then when I turn off the water fill the light does not go out. I tapped what I think is the fill relay(??) see pics attached and it still does not go out. After a few minutes I try turning it off and it does! What is up with that? Is there a pump associated with the fill switch that suck water or do you require shore water pressure? If that is the case, how do you suck up vinegar etc to add to your hot and cold tanks, and lines including the Aqua hot coils??
Oh and my schematic shows no fill breaker on the breaker panel
On my coach the latching relay is different than those. That looks like a standard relay.
To put vinegar into your system would be the same way to put the antifreeze into the
system. Usually there is a three way valve put in just before the inlet side of the pump
and you would put your vinegar or antifreeze in that way. The fill switch is left off.
Have you a pic of your latching relay I could view?
There's some latching relay photos in the thread linked below:
Water Pump Will not turn off (https://www.foreforums.com/index.php?topic=44326)
Peter,
The simple way to get vinegar into the system is have a short jumper hose about 6' long that has a fitting on one end that will screw onto the pump suction. This does entail removing the inlet piping off the pump and installing the short hose. Once hose is installed stick other end into jug and turn on pump. Open each spigot one at a time till you get vinegar then proceed to next spigot. Our coach takes about 3 gallons of vinegar.
The other way is if you have a spare water pump that you replaced and still runs use it to pump vinegar into the system. Seems like there is a how to thread somewhere here on the Forum as this is how we acid wash our water system.
Mike
Never thought about the spare water pump thing which I actually have after replacing it with a newer model. Excellent idea! I finally got the vinegar in and am leaving it overnight then draining it out. I got some Camco spring fresh tomorrow which I will flush into the system tomorrow
Now if could get the latching relay to work...and to be able to find it!!
Peter,
You show a pic. of it in reply #4 the 4th pic. You have 2 latching relays in that shot one should be for the water fill valve and the other should be for the water pump. Yours are the old style like was used on the VW (Bosch) head lights not the Finder style like oldguy shows in his post on the other thread. Water pump pulsing and fill switch malfunction (https://www.foreforums.com/index.php?topic=44455.msg450301#msg450301)
Mike
Well I will replace the two of them( I presume they are the same) for a fresh start
Thanks!!
Those 2 yes
If you want to upgrade to the Finder style Typ 20.21 that is also doable. Slightly more complicated than the Bosch will be, as it (the Bosch) is just a straight swap out.
Mike
Mike that means the switch you turn it on is the same switch that you need to shut it off
with?
The latching relay is there to be able to use multiple switches at different locations to turn on or off at any location or turn on at one place and off at another. The switch just shows the relay a ground so if you want to add 2 or 3 more switches at different locations you can.
