I have tested out the battery bank and all is fine.
Water supply is plastic and filter is clear.
I do not have a calorifier, just a morco water heater.
Voltage drops around .5 volts after 30 secs, pump is hot at this point and cuts out.
I havent measured the drawn current as a I believed the hot pump was a clear indicator of being faulty, swollen diaphragms/seals I suspect?
I’ve just done a little research and it seems if I want higher shower pressure then I need more hot water which means I need a larger capacity water heater……….does that sound about right?
I’m thinking buy the 45psi pump and adjust pressure to suit current system then purchase a larger heater when funds allow and readjust pressure to suit.
Does that sound about right or am I thinking too simply?
