Using NRVs before a Power Shower Mixer

yeahdisk · 20 Feb 2008

Hi

I'm currently installing a power shower, and tee-ing off from the pumped supply for my monoblock basin mixer as well. (previous post on the issue is here: # )

As advised i've bought some inline NRVs (15mm copper compression) to go before the hot & cold for both the basin mixer and shower mixer valves (so 4 NRVs in total).

Question 1: are these NRV's going to reduce my available pressure by a lot? (The ones I have look very similar to these:

Question 2: Instead of installing the NRV's after I have tee-d off for the basin mixer and shower mixer, could I just install them before I tee off (thereby reducing the number of NRV's required from 4 to 2?)

Thanks all,

Chris
