The flow rate from my cheap n cheerful unbranded 'Chinese' monobloc mixer tap was worse than the old tap it replaced. I decided to upgrade to a Grohe unit (assuming it would be good gear as they are a premium brand) and thought about changing the mini isolating valves to proper lever type cut off valves to improve the flow.
I purchased a Grohe 'Concetto' tap online and was surprised to find it arrived with 'euro' sized 3/8 fittings, so the the job is now stopped whilst I source some adapters. :veryangry2:
Having looked at the flexis on the tap, the internal bore is a meagre 4.5mm compared to the internal bore on my std feed pipes of 13mm. These flexis are not removable, so I cant simply upgrade to wider flexis with 1/2 fittings.
Being a total noobie, I would like to know:
1) Will Grohes 3/8 flexis kill the flow rate?
2) The tap is specced at 13L flow a minute at 3 bar. Is that good/bad/indifferent?
3) Given the small bore flexis is there any point in upgrading mini isolating valves to a lever valve?
Thanks for any input!
