Replacing stopcock with lever ball valve?

[acone]

Moved into a new home recently and asked a plumber to replace the main stopcock (traditional brass tap style) because it hadn't been used in years & was stuck/stiff. Made more sense to replace rather than try to service it. However without asking the plumber has replaced it with a 15mm 1/4 turn level ball valve.

So I'm wondering if there's going to be any issues with using a ball valve as the main stopcock and also in terms of insurance/water companies, regs etc. should it be a 'stopcock'.

He has also installed the ball valve in a way where the level drops to the 'on' position which I guess is not ideal either. Would it be better to err on side of caution and change it back to a traditional stopcock? which in some ways I prefer and if worked every now again should last a long time. Which would you opt for?

Thanks.

Well, the lever ball valve creates lower resistance which in turn maintains flow rate.

Is your flow rate on the low side?

We have water tank in the loft. Pressure has been fine before and after change. Wondering if it's normal/recommended practice to use a ball valve as the main stopcock.

Thanks.

Personally I would recommend it but some wally will come along with their interpretation of some reg that no longer applies and tell you you need to install a traditional stopcock

Should be a stop tap to bs 1010. A lever valve could be fitted above.

1st question under general installation section at bottom. As long as they are full bore and WRAS approved then it seems they meet the criteria
