It cracked!! :'(
Damnit!! i was washing the smaller diameter tube from my Kaplan pump in pretty hot water, rinced it off in cold and “CCRRAACCKK” a huge bloody gash appeared in the side of it!
Man i study physics at uni - i should know better!
Anyway the thing is that i have always prefered the smaller diameter tube to the big f***er.
Do you guys think i should just use the big tube or buy myself a new thin one?
