Well today I:
1. Rerouted the hose from the pump to the unit and eliminated about 3 feet.
2. Removed the Y and for not only have the small unit pumped.
3. Removed about 1 1/2 feet of the host between the strainer and the pump and have it in a very nice straight run now.
4. Cleaned the strainer.
5. All fittings are now nylon and double clamped with stainless.
After doing all of that I had much better flow at the pump, it actually shot water
a few feet. But when hooked to the unit I still only had a trickle.
After futzing with it for a couple of hours and making a mess of the "almost" completed VBerth, I finally hooked the garden hose to the outlet side of the coil and back flushed it and immediately had a nice bunch of junk push out of the inlet. I hooked everything back up and have very good flow through the entire system now. The unit runs fine and the high pressure switch did not pop out, and good cold air was produced!!!!
This pic might not be very interesting to the casual observer, but I am very proud of it!!!!
So now I need to make a decision. One pump or two. I did find out that the pump relay box is bad, it energized the pumps even with neither AC unit were on, so if I go with one pump I would have to replace the pump relay box.
If I go with 2 pumps I have the 2 through hulls near the unit that were originally for the head
, we went with a composting unit, so they are not used, but I would need to add a strainer as well as the pump since there isn't one there now.
Cost wise it would probably be less than $125 more to do a second pump as it would be to replace the relay box etc. And the system will definitely be simpler with each unit wired and plumbed separately. So I am kind of leaning that way, anyone have a good argument for going single pump?
I couldn't source a nylon Y or a 1/2 threaded to 5/8 barb fitting locally so will have to order those if I go with one pump
