Re: Rinnai HWS & Pressure Tank 18Sep 12, 2016 12:32 am As a matter of interest, I have just found my pump's installation instructions...all such paperwork goes in the one cupboard! The plumber told me that the pressure tank had to be set at 20 psi but I have always had it a little lower than this because of early gremlins. The cut in - cut out settings are 140 - 280 kPa and so I decided to look for the instructions after I realised that 140 kPa is 20.3 psi. It turns out that the tank's factory pressure setting is 19psi. Still, 19 psi with a 20.3 psi cut in is a bit fine for my liking. I think that your intention to have a 46 to 48 psi cut out will be damaging to the pump and waste energy. 3in1 Supadiverta. Rainwater Harvesting Best Practice using syphonic drainage.

Re: Rinnai HWS & Pressure Tank 20Sep 12, 2016 12:54 pm firebird Oh, so if the pressure tank is 30 psi are you saying I only need a cut-out a few psi above that? I am somewhat hesitant to answer your question in this instance because a lot of people read these threads and their pumps and situations will be different and I would not want someone taking on board a recommendation given to you and using it for a different situation. The cut in pressure is always above the tank's pressure, if you persevere with the pressure tank, maybe initially try 3-4 psi above the tank's pressure. Also be aware that the pressure tank's pressure must be checked at least annually but preferably more frequently than annually. The tank must be drained before the pressure is checked and adjusted. Pump types vary as do the applications such as some properties having underground tanks or submersible pumps etc. I mentioned my Davey pump earlier because it also has a 35 meter head and we were discussing different pressure switch settings when pumps were fitted at the factory with a pressure tank but it is a centrifugal pump whereas yours is a turbine pump. Turbine pumps are known by various names and you can read about them below. The operating differences between centrifugal and turbine pumps are also explained. You Tube is also a good source of information. http://www.rothpump.com/regenerative-tu ... -head.html The statement below is taken from the link above. Regenerative turbine pumps should not be operated against a closed discharge, unless a pressure relief valve is used. Install a pressure gauge on the pump's discharge, observe the manufacturer's pressure limits and you'll increase the pump's life. A centrifugal pump usually has the cut in pressure 2 psi above the pressure tank's pressure but this also depends on the tank's elevation if applicable whereas some other types of pumps might require 5 psi. 3in1 Supadiverta.
