SubscriberHas anyone got a good recommendation for a quiet 12V pump to be used for a shower?
I've currently got a Jabsco ParMax which runs at 11L/min, but it sounds like a coffee grinderWell, not quite, but it is definitely not what you'd call quiet. It was not cheap, at around $150 I think, so I was expecting it to be quiet.
It is fitted with rubber feet, but attached to a panel wall, and that seems to amplify the noise.
For a test, I bought a little "silent" food grade pump, but it hasn't got enough grunt for the shower, although it is almost completely quiet!

I thought most ran Flojets or Sureflows or something.

Hi David, I've got one of these connected up in my dormobile -
Shurflo 12V Revolution Water Pump 11 3 LPM Filter Caravans Motorhomes | eBay
Although you can hear it I wouldn't say it was very noisy, I've got it connected to an external shower and the kitchen sink. It's screwed to an mdf board and lives in the rear wheel arch.

Subscriberx 2 for the bilge pump. They are very quiet but can't be installed in line like you may want. I have a sureflo for the sink and it is one of the quieter inline pumps i've come across but like all diaphram pumps - it still makes some noise.
If you need to contact me please email homestarrunnerau@gmail.com - thanks - Gav.

SubscriberOK - I'll try a bilge pump next.
The little pump (inn the big picture above) seems to be a rotary pump, compared to the Jabsco/ShurFlo which are diaphragm pumps.
What's the benefits/disadvantages of one over the other?
AT REST
Bilge pumps are low pressure rotary pumps that have no ability to self prime so their inlet must be below the water level. Diaphragm pumps can lift water out of a low mounted tank no worries. Diaphragm pumps also can build up pressure so in conjunction with a pressure switch can be left switched on and won't run until a tap is turned on.Originally Posted by spudboy

most but not all bilge pumps have ot be installed in tank and unless already immersed wot self prime. They are generally a non positive displacement pump which means they dont deliver a lot of pressure which can be an advantage in some cases and they also allow you to draw out through them without the pump running. they also allow the line to drain back to tank and generally you operate them by applying the 12V on demand as opposed to turning them on and letting a pressure switch turn it on or off.
the diaprhagm, plunger and gear type pumps are positive displacement, give good pressure but cant be easily drawn through if they fail. If you rely on a pressure switch to turn them on or off you're going to find all your leaks in the plumbing. and if you accidentaly leave the switch on and nothing leaks the pump will cycle intermittantly and can drain down your battery.. the more the pump cycles the faster it wears out and develops "slip" which means it cycles more often to get to pressure and if run dry enough long enough will kill its priming ability. (which is what tends to happen when the kids turn the pump on run the tank dry an leave the switch on while they run to mm and dad to tell them the water stopped)
