I shave both my face and head
once a week. Do it in the shower
, never had a problem with the pumps or the box they are in plugging up yet, Connie also shaves her legs and such in the shower
also! again never a problem, at least so far !! Of course I use bilge
pumps for shower pumps that might be why we don't have problems. Of course there have been times I cleaned the box out, but mostly the stuff I scraped out of the box was soap never realy noticed any big amount of hair in the stuff I took out ! a little but nothing that would stop a pump! I clean the sumps about the same amount as I clean the bilges, a couple of times a year! But we have pretty clean bilges no real oil leaks
, and almost no water! As I said we have been useing the shower to shave for many years with no problem!
