I very well see your point of going with pressurized fresh water, but
this would give us other problems. My boat is a 41 feet sailing boat,
and with four people on board, and sailing in the Med most of the
time away from marinas, we already use all the water capacity we
currently have.
A toilet that uses pressurized flush water uses about 3
gal/day/person...less if you use the lee rail as much as possible.
So, I guess my options are limited to: a) silencing the intake pump
by selecting the best one and/or installing it in a sound-proof
enclosure b) setting up a small pressurized sea water system for both
toilets. Although this can be purchased of-the-shelf for fresh water,
I have not seen anything similar for sea water.
I've never heard of one.
And I imagine the
fresh water ones would have problems with sea water. Also, is the
Raritan solenoid valve designed to operate with sea water..?
The solenoid isn't a pump, it's just a valve. The water pump has to be
on to keep the system pressurized...the solenoid valve opens to let
water flow in to the toilet when the flush button is pushed..closes to
block the flow of flush water when the flush button is released. It's
essentially just an electric version of a faucet.
So may be I should go with a) using a 4-diaphragm pump.
Diaphragm pumps "hammer"...so you could just be trading one noise for
another.
Often, it's not just the pump that's noisy...the boat hull resonating
can amplify it. So one thing you might try: mount the toilet on a thick
piece of foam rubber to provide sound insulation and deaden as much
sound as possible.
Otherwise, unless you're willing conserve your fresh water more, you may
just have to live the noise....'cuz ALL sea water electric toilets are
noisy. Some--especially the Jabscos--are noisier than others.
Or...you could go back to manual toilets.
