Disassembling the pump is quite straightforward and for the main part seems well engineered. The inside was full of crap and dirt as usual with cheap Chinese stuff and some of the o rings where damaged. Surprisingly the two main tubes are made of stainless steel which is a bonus.
While it was apart I took the opportunity to polish everything to a mirror finish, hopefully this will give the seals a fighting chance at longevity.
Now it’s reassembled it works fine, so for the money I’m very happy.
