Hi i am looking to buy a 12 Volt pump to hook up to the sink tap on my camper. I am want to run the
water through a filter on the sink side of the pump. Does anyone have any suggestions of a recomended psi and a flow rate for this kind of application. I will only be feeding one tap but the filter will take some of the pressure and flow out of it i guess. cheers dave

Dave I assume you're in WA. Camec in Welspool
Perth have these pumps - ring them or go and have a look at their pump specs. Regards Dennis.

There is a Camec in Archerfield west of
Brisbane.
Boat
places also carry suitable pumps as does BCF.
I'll be watching this thread, a pump in the camper trailer is on the to do list.

Hi Dave
I've just gone through the exercise of checking my KK. The pump is 3.8 lpm (which is quite adequate). Connected to a small in line filter it takes a bit more effort for the pump to push the
water through (noisier) but still works.
Larger pumps (Shurflo IIRC) are used in caravans.

I meant to add .....
shop around. There is some real ripoffs out there.
Better looking at ag sites rather than RV.

Thanks
Malcolm do you think the 40psi option would be better through a filter? I am assuming you have the 35 psi option. cheers dave

Yes,
mine is 35 psi. I'm not qualified to answer the Q. Just that 35psi still seems adequate through the filter. (just noisier - compared to no filter).

hi
i have a 12v flojet pump on my camper trailer that i removed from my ex farm sprayer unit it delivers 5.8ltrs/min and has an adjustable pressure valve it was 12 yrs old when i transfered it to the camper all i have ever done to it was cleaned out the valve housing and valve seats that was two yrs ago it worked long and hard on the farm and parts are still availuble for it if needed as i checked before installing it in camper
i can highly recommend it i only have a 50 ltr
tank and a tailgate sink with a small tap it works a treat and is more than ample to fill the billy and also run a shower head off an external tap on the outside of camper hope this is of help

hi
it also has an inline filter between
tank and pump which is an absolute must to protect pump valves or they will fail at the first entry of dirt or dust that's a golden rule for any brand of pump

Mate,
if you are lopoking for a good reliable pump used in both marine and caravan
applications, Shurflo have a great reputation for reliability.

Either this one,
Parmax 2+ Then go into the Parmax range, look at Parmax 2+.
Or this one,
Shurflo
This one may be a better option as you can use a domestic style tap to regulate flow and it'll slow down or speed up to maintain a constant pressure,
Jabsco Sensor Max VSD Then go into the Sensor, Dual and Ultramax Range, look at Pressure Max VSD.
The lowest flow rates appear to be around that 10.0 l/sec mark. The Sensor Max should throttle back to stop the pump short cycling.

I have one hooked up in my Jayco - permanently hooked up through the plumbing and the 12v system with a momentary switch via a relay.. I got the pump from ebay
similar to this -
http://cgi.ebay.com.au/NEW-12v-35PSI-Water-Pressure-Pump-4-3Ltr-Min_W0QQitemZ320425814607QQcmdZViewItemQQptZAU_Home_Tools_Pumps?hash=item4a9addea4f&_trksid=p3286.c0.m14
Can draw you a simple diagram if you need - switch and relay i got from Jaycar - also available at any dick smiths
as i dont agree with the MODSQUAD ON THIS
FORUM and the stupidity of them - i am posting this message in the hope it makes its way to your email as i have no interest in helping this site whilst these MODSQUAD's hide like gutless hall monitors net policing every word
