Anyone know of a supplier of 20mm internal dia. I wish to try the method illustrated in Diy Doctor.

Try using a washing machine hose.

is this to clear an airlock ?

if it is then normal garden hose will do, hold on hot tap with tap open, then open cold tap and hold onto that too.

You need to have a good grip and cover most of the tap outlet.

Should only take about 30secs to back fill
