Soda Syphons are fairly simple beasts, but are prone
to two main problems. Firstly, the rubber parts perish over time and
so the syphon loses pressure. There is no cure for perished rubber,
so you'll have to source a spare part. The best place to look is somewhere
like a plumbers, where they have rubber gaskets. Take your part in &
see if they have anything similar. Enthusiasts may wish to start with
a lump of rubber and make their own!
The second problem is losing the bulb-holder. Many second-hand
syphons are sold without this precious item. See
here for more details.

it. Before using a syphon for the first time or if the syphon has been
stored for a long time it should first be rinsed out. Follow the Instructions
