Hi, It's time to renew on old pump (a 12V Jabsco Par-Mate) that is spec'd: 11LPM at standard (25psi) pressure, no accumulator in system. I am condidering upgrading to a higher flow rate of about 16 LPM and possibly using high pressure (40psi) and would like opinions on;
- will the increase to 40psi create any issues upstream or downstream of the pump that i will need to guard against ?
- would you recommend install of an accumulator at same time ?
- choice of manufacturer ?
- will my shower be even better 
?
regards
suk
