Hi, Just a few queries I wonder If I can get some advice with please
I'm shortly going to be fitting a new bathroom. Part of this will be fitting a Mira Atom shower with 2 shower heads and am planning to fit a Salamander 1.5 bar CT50 xtra Pump in the airing cupboard to feed shower only. I will be plumbing in myself. Have already taken separate supply from CWST to pump location in 22mm pipe, to be reduced to 15mm just before the Pump connector.
Its a 1 1/2 storey house with CWST in very tight Loft space. Hot water cylinder ( Indirect, Vented 140 Ltrs ) on First Floor, and Shower on Ground floor approx. 2.5 Meters from Shower head to bottom of CWST. Upstairs also has a wall fitted Redring 520TS Pumped power shower
Questions I have are
1) All Pumps I looked at online state a minimum of 50 Gallons CWST capacity. My Tank is 40 Gallons. Now I know that this does not comply with the Pump warranty, and there's not a lot I can do about this except hope the pump runs for at least a couple of years before I have to buy another. This limitation is one of the reasons I didn't go for a higher spec / quality Pump such as a CT force or ST monsoon. There's no chance of fitting a bigger Tank dues to space limitations. Fitting an extra tank is just also physically not possible. Its just me and the Missus in the house so demand on water is not high. Very rarely would both upstairs and downstairs showers be in use, but when family come to stay, it would be quite possible that both are. The CWST is a Ferham FLT 40 coffin type tank, with a Lid on each end of the Tank. I have limited access to each end of the tank also by a loft hatch each end. My question is, is there any reg or reason I could not if another Ball valve on the other end of the Tank to Decrease the rate at which the tank level drops when the shower pump, and also other shower are in use , Mains water pressure to the tank is good, so I'm sure there is enough pressure to sustain two supply's to the tank. If not possible, are there faster filling Ball valves that may be an option to prevent tank level becoming to low to quickly.. Maybe 40 Gallon tank will be plenty ???
2) The hot water supply for the Pump will be coming from the side of the HWC. There is a Secondary return plug in just the right position, just below the dome of the tank and above Pump position. Instead of using an Essex Flange ( Don't have the Bottle to cut a hole in the tank, and due to Tank being close to the slope of the roof, no room to use one of the recommended Top fitting flanges unless I uncouple the tank and move it over to fit the Flange) I have a 1" to 22mm fitting that I will replace the Plug with. I have ground the pipe stop from inside the fitting , so the 22mm pipe will go through into the Tank. Has anybody done or heard of this before, or foresee any problems with this idea ?
Any advice would be appreciated
