I have got a problem with water flow into the downstars toilet and shower.
The stopcock is fully open and I get about 10 litres/min in from the other taps.
The toilet and shower get a lower water flow down to about 2.8 litres/min - naturally this plays havoc with the electric shower
The kitchen (next door) acheives 10 litres/min. Is it acceptable to plumb in a pipe from the kitchen over to the downstairs toilet/shower feed? and keep the connection to the exisiting feed.
This should then allow the downstair toilet/sink/shower to get water at an acceptable rate from the kitchen & the orig feed pipe - i.e this will have two routes to the incomming supply pipe? - naturally the easiest route will be taken by the water automatically.
Is this OK?
