The outlet from my cold water tank is a 28mm pipe, the valve (which hasn't been used for ~ 30 years) is jammed. I'd like to replace it with a ball valve (aka lever valve ?) but Peglers website says their valve is 96mm long and the current one is 113mm. I reckon my chances of, ahem, finding (in a skip ?) a short length of 28mm is zero and I don't want to buy 2 metres. In practice I'm going to have to cut a bit out of the pipe and insert something a few centimetres long (the pipe run is over a metre so that's no problem).
Various ideas:
a) Use a screwdriver slot isolating valve which I'd hide with insulation, but I can't find a 28mm one.
b) Use a repair coupling, but again I can't find a 28mm one.
c) Use a pair of 28mm to 22mm connectors and a short length of 22mm pipe (which I've got).
d) Use a T connector which has a 15mm branch and use a blanking disc to block the branch; link to a suitable connector:

Currently this is my favourite, if I did this should I point the branch downwards so as to avoid an air pocket ?
e) Use a suitable Non-return valve; such as (link):
