I am planning on fitting a 1.5 bar max Showerforce Turbo 2 Shower Pump into the airing cupboard /Hot Press and the space and the way i want to plumb is the easiest way I can find this means placing it before the copper water heater cylinder and not after it .
But I am wondering if I do it this way will it pressurize the copper immersion tank so much that it will cause the water to travel up the expansion pipe to the cold water storage tank in the loft?
To make it easier to understand I have uploaded a diagram here of what I want to do:
Use a single impelelr pump instead and you will not have to interfere with the pipe to the cylinder. At present you do run the risk of pumping water through the cylinder and into the vent pipe.
Care! you need to know the water flow rate into the header tank and the water flow rate of the pump; if inbalanced then you could run the header tank dry before the cold mains into it can recover. This will as I say depend on the size of tank and water flow rates. If you are not sure I would reccomend getting a qualified plumber out to consult.
