I'm in the process of installing a concealed shower mixer valve that has 3/4" BSP female inlets and outlets. The hot and cold pipework from my balanced pressurised system is 22mm so i have teed new feeds off to the shower in 22mm (rather than reduce to 15mm) and connected to the valve using 22mm x 3/4" male couplers.
The issue I have is that I have been hunting round for a nice shower head and arm for mounting onto the ceiling. Everything I seem to find specifiy 1/2" BSP fittings on both the shower head and the arm. Is this the common standard or I have I just been unlucky on where I have been shopping?
Now I can easily continue to install a 22mm outlet pipe from the valve and connect to the shower arm with a 22mm x 1/2" female coupler, but would I get a reduction in flow rates out of the shower head due to the slight restriction in the smaller 1/2" coupler? Just seems strange that the valve is 3/4" BSP outlet, but all the shower heads/arms I have found are 1/2" BSP.
Any thoughts on whether the 1/2" BSP would be a bottle neck and should try and find a 3/4" BSP shower head/arm, or am I just worrying about nothing?
