Cheers m8.I reused mine - it's just a spring in a tube and fairly easy to clean.
All the hoses fitted fine for me.
Just ordered the pipe.
Are the other valves long lasting (the one with the cable ties on). Was going to try n get a new one but wont if i dont need to.
Re the cable ties, not sure what they're on there for. The valve that they're attached to isnt damaged externally at all.
