I am installing a shower pump. I want to use flexible coupler hoses to help minimise the vibration. There is a 22mm supply pipe from the tank in the loft, and the pump has 15mm fittings.
So I'm using a 22mm to 15mm reducer, the flexible coupler hoses (300mm long) have an internal bore of only 10mm. The pump requires minimum 0.01bar on the inlet.
On the outlet it's 15mm connection on the pump, through the flexi hose, and back to 15mm pipework. Shower head is rated for 12.5L a min. Pump is rated max working head 10m (1 bar)
Could someone more knowledgable about flow rates and such, tell me if this is a workable idea or not?
This is a Mira pump, but I notice the official Salamander flexi hoses only have a 12mm internal bore. Internal bore of 15mm copper is about 13.6mm.
So is 300mm length of hose at 10mm instead of 13.6mm going to make a massive difference?
