Solar container device cannot maintain pressure

Constant pressure loss is due to evaporation of water at high temperatures through automatic air vents. You should install (if not already installed) special air vents for solar systems with ball valve before air vent. The most common support calls we receive about the TPP are about battery charging, priming the pump, pressure settings and checking for leaks/air in the line. We have a solar installation with 2 Viessmann collectors, which is quite unusual because the tank (250 l) is placed in the attic, horizontally. This resulted in the fact that it was not possible to supply the heat exchanger inside the tank with solar fluid. Each of these can be used for different purposes, and therefore come with their own unique set of problems, so here some of the most common problems (and solutions) you may encounter with your new solar pump. The primary purpose is to power a submersible 240V 2HP deep well pump and a 120V transfer pump that moves water from our 2k holding tank up to a larger 10k gallon tank that is 1000ft away on the property.
