The ejector has an orifice and Venturi tube that is supposed to be matched with the pump and the pumping depth, I don’t think that there is a “ universal ejector “

It should go in the cold water supply line, some ware around the expansion tank. The the intent of the code is to prevent the water in the tank from being sucked out if the city supply pressure drops below 0, ( think fire truck pumper hooked to a hydrant nearby) they don’t want the water in your...

Glad to hear you got it running!

Is the heat pump water heater located in a closet? If so it needs to be able to circulate ambient air in and out of the closet, if not the closet air temperature will drop, and then there won’t be sufficient heat left in that air for the heat pump to remove and the recovery rate will be Even longer.

I would suspect that there is a high pressure cutout switch on the high side of the refrigeration circui, by stopping the water flow through the unit the refrigerant pressure would climb very guickly and trip the HPCO switch. Shown in wiring diagram,on the right side midway down.

Box one, red and black on the 3 wire cable to traveler terminals, black from the 2 white cable to the common terminal ( different color than the two traveler terminals), box two, red and black to traveler terminals and white to the common terminal.

Instead of putting bandaids on a obviously poorly designed system, why not re-plumb it the way I suggested in post 16 and take full advantage of having two tanks to draw from and nearly double you draw down and recovery,and save some energy by putting the pump on a thermostat also. 6000 sq ft...

If the start relay Is not taking the start capacitor out of the circuit, it will keep the motor start winding stay engaged and will cause the motor to overheat,

Time for a new water heater! The sediment in the bottom of the water heater has become solid ( like glazed tile) the poping is from water seeping through cracks in it and becoming trapped between the steel bottom of the tank and the hard sediment, when the burner comes on that water flashes to...

Generally Pumps in series doubles the head, pumps in parallel doubles the flow.

Sounds like your pump is cycling on it’s internal overload protection switch, the pump runs for 30 seconds, gets hot and turns itself off for 2.5 minutes and cools off then restarts, and this cycle repeats. Most likely the pump will need to be replaced. Or there could be a bad run capacitor in...

Lime is a base material, it has a Ph of~7 it does not eat copper! Holes in the copper tubing would most likely be caused by someone strapping the tubing to steel reinforcing wire mesh or rebar, my house is 75 years old with 4000 sq ft of copper tube radiant heat, never had any issues. The OP...

First you need to find a new plumber! The pump MUST be on the return line, connected to where the boiler drains are at the bottom of the two tanks, via a balanced tee arrangement ( a tee with the bull exactly the same length from each connection point at the tank), the cold water supply MUST be...

hard water is simply water with a lot of different minerals in it, these mineral tend to leach on to the hottest surfaces, which in a boiler is the inside of the heat exchanger tubes, as this mineral builds up it insulates the water from the tubes, now the water can no longer carry the heat out...
