Cleaning a suction valve:
The suction valve is basically dismantled, cleaned and reassembled in precisely the same way as
the discharge valve.
However, note when assembling the valve seat (2) that it should face the opposite direction. (The
smooth side should point in the direction of flow for all valve seats (2).)
