Between the temperature controlling faucet and the cleaned shower head, our boat showering life has never been better; arguably better than we have at home. The flow and pattern improved dramatically after soaking the shower head in vinegar, but I saw a few unexplained bilge pump run counts on our monitor. Turns out the new flow rate is overflowing the shower sump.
Our "shower sump" is a rather tiny box (from Jabsco?) that collects drain water from the main shower, the day head shower (that we virtually never use) and condensate from two FCF air conditioner coils. The small Rule bilge pump is controlled by a Rule float switch that discharges through the side of the sump and up to a thru hull fitting. Between the switch and the pump, the sump never gets pumped lower than about a half inch of water. The effective minimum depth is more like one inch though because the thru hull hose drains back into the sump when the pump stops.
The effect of the clean shower head is that more flow is coming from the shower and when the falling level switch stops the pump, the volume returning from the thru hull hose causes the sump to overflow. So the question is, should I increase the shower sump volume or change to a Whale Gulper that may be able to pump faster, draw the volume lower, or stop the returning flow from the thru hull hose with its check valve effect?
