Pressure pump or switched on/off

[Hatto]

I have just purchased a camper trailer and want to fit a 12v water pump to feed a sink tap at the tail gate. And maybe another connection on the side for a shower. I have seen on eBay the tap and pump combo's with an on/off switch on the tap like this.

The other option is of course is a pressure pump. Turn the tap on and hey presto the water comes out! Like this.

What would you use and why? Also what spec pump would be ideal for a sink tap (litres per minute and cut out pressure). They seem to cut out at between 35 and 80 psi. Look forward to hearing your thoughts

If you want to connect the shower I'd get the automatic on/off pressure switch.
Also, if you want a shower you need the think about the litres/min.
A normal water saver shower head does about 9l/min.
Getting 4l may be a bit slow. Depends on your expectations. If carrying your own water the key is to use it sparingly though.

My van has an external tap fed by the 12v pump. I connect a normal hose trigger head to it. The auto pressure switch is the way to go. Use this to clean sand off feet, wash-down after surf etc etc. click and spray..no fuss.

I use an auto switching pump on my camper, 3.5lt/min for general use. Be wary of a high flow rate pump. You'll chew through water like you wouldn't believe..

For showers I use a portable Primus unit fed out of a bucket. That way I know precisely how much water I'm wasting.

Most water pumps seem to have inbuilt pressure switch anyway, I got this one with my Dolium tank . . . 12v pump

I'm running an 11.4lpm Shurflo pump for my rear water tank. This pumps via a BEST filter which knocks the pressure down a fair bit. I've also just finished mounting a second Shurflo 11.4lpm pump under the bonnet which has an inlet/ outlet on the bulbar. I run a small tub of water and recirculate it via a 40 mesh screen for showering.

I got sick of the usual poor pressure with most camp showers and this set up has awesome pressure and so long as we recycle the water, we can shower for ages on 3 or 4 litres. Even with the pressure pumps it is advisable to have it switched. Otherwise you risk pumping all your water out if you develop a leak.

Stevens right, looking at your OP, and the bit about shower . . . you need a bit more pressure for that, especially if going through a fine filter.
With mine, it's just one tap for drinking / cooking purposes, and a lower volume pump is actually good as it keeps you from using too much !!
You have to restrict showers a bit depending on our tank size / days out etc, very easy for some to enjoy the hot shower just a little too long

My abs brake pump rotor is broken...

Hello everyone, I own a montero 2001, diesel engine, 4m40, and my brake pump stoped working, and i dismounted it and seem that the electric cables and clips that goes from abs pump to the rotor were oxidated and in bad conditions.

So i cleaned up the cables and electric clips and probe it. The electric motor worked! I remounted the pump again on, and then stopped working again..so when i desmounted it again, i could see tha the motor had lots and lots of sediments from the contact graphites and that was stopping the rotor to start.

While trying to open the motor of my abs brake pump to clean it up I accidentaly broke it!!. I broke the magnets and also the rotor. it has not rebuilding opportunity.. it is to damaged.

Does anyone know what is more reliable..Buying a new motor for the pump or downgrading to basics pressure pump brakes (not abs pump)??

I can see that to motor cost round close to the Hundreds and here in santo domingo is no cheap to repair the abs pump..!!
