Well after installing my Westfalia kit in my syncro I have come to the point of installing the kitchen sink stuff. I just got my new Delta six faucet and now it is time for the Water pump. I see that 2 types are out there.
http://www.gowesty.com/ec_view_details.php?id=2428&category_id=128&category_parent_id=
and this type
http://www.van-cafe.com/home/van/page_92_1283/westfalia_h20_sink_pump_early__under_sink.html
I would like to get some info on the pro's and cons of each unit before I order one. Kind of like a vote witch one is the better unit. My H2o tank is the type with the level indicators on the side. Thanks folks VW Logo

I'd suggest just replacing the pump with the type yours originally had--or the donor van originally had. Winston's original was a submersible, that's what he got as a replacement. I did find it necessary to use Seal-All to keep the connections tight, but that worked quite well.

I'd worry about there being subtle differences in the hoses and configuration of the faucet that might be a problem if you switched types--but the advice is worth what you paid for it.

Best!

I ordered the van-cafe external pump and it does not have enough power. Water output was enemic...1 litre took 2 minutes.

I then bought a third party generic pump and it does the same in 30 seconds. Still not great but better.

Hello thanks for the info guys. gbrandt did you mount your pump to high in the cabinet? I did this before on another camper and it had a hard time keeping itself primed so it worked extra hard to pump the water. I mounted it lower and it ran fine. I hope this helps.

No, I mount the pump right on the floor, under the L shaped wood in the cabinet. The pump was simply no flowing fast enough. .2 GPM I would guess.

Just replaced my - 1986 Westy - in-tank pump, OEM style from Go Westy, works pretty good if you ask me, it pushes a lot of water to me and I am not sure I would want more. In my research an aftermarket alternative would be a nice replacement but I wanted to stick with stock after reviewing all my options.

I was wondering how dose the in tank style pump mount up? It is a bit cheaper pump price wise and I bet they last a little longer too?

It doesn't really mount. It just "hangs" submersed in the tank.

Yep -- just dangles in there. I thihk my first pump lasted about 20 years, replaced with the same blue submersible unit.

Mine is pretty much always submerged... i.e. the tank does not sit dry. That may contirbute to longer pump life... dunno.

Being as my '88 had the undersink mounted pump, not the submersible, I replaced with a like type fitting.

Replaced the puny VW original with a Proven Pump (bought at Princess Auto in Canada), but I imagine they are available at US suppliers of farm equip, tools, etc.

This pump has a plastic body, 3/8" in and out fittings, and works like a charm. Throws water through our shower hose about 6 feet long.

I think Canadian vans had external pumps and US vans had internal pumps.

Just replace with what you already have.

I thought so too but my cdn Syncro has a submersible. I replaced it when I bought the van with a Gowesty version and it works great.

In the U.S., all Vanagons thru 1981 had inline pumps; the switch to submersible began sometime in 1982. As with many Westfalia changes, they didn't necessarily follow a specifc chassis number, so '82-range campers could have either. There is no inherent advantage to either type; it's easiest to simply replace the pump with the same style you already have.

I got my Westfalia interior from Canada so it had the external pump system. The pump was not working so I replaced it with a more powerfull Flojet model like this http://www.campingworld.com/shopping/item/flojet-quiet-quad-ii-water-pump/9372

I installed it in the secret space between the water tank and the cabinate to the left of the fridge. The pump has a good flow rate but it is noisy and sometimes has a problem priming when the tank is empty.

I am thinking of going to the submersible pump partly because it would be quieter but mainly because in winter it is desirable to have a system that drains back to the tank when not in use and therefore does not freeze up. You can only do this with the submersible pump.

Hi, Since my sink pump was not working, I bought a Jabsco replacement ("single sink pump") at the marine store that looks just like the old except is dismatleable rather than glued together. Put that in, but without water it would not run either. Turning the knob makes a klunk sound as though a relay is being activated. Is there a relay in this system that keeps the pump from running dry? Any other ideas about what to check? Mine is also an external pump.
Thanks,
...Tom

OK, it turned out that the pump worked when the engine is on, so I disconnected the white wire under the driver seat from ground (I had assumed it was ground because it was bundled with the red wire, which I re-routed to the new second battery so the LED panel wouldn't draw down the primary battery). The sink pump now works, but can anyone tell me what the white wire goes to (don't have a Bentley)?
TIA

Does anyone know if it is simply a direct swap to replace the external pump with the submersible one (i.e. are the electrical connections compatible between the two)?

I ask because I would like to replace my tank with a non-standard tank (that would not fit the external in-line pump config) and thought it would be easier to just go with the drop-in-the-tank submersible model. Thanks in advance.

Oh yah baby Laughing I replaced mine from the under the sink type to an in tank one. WOW it works great. Simple to instal. Half the price of some under the sink brands
. You cant go wrong with the German made in tank one. Both Gowesty and Vancafe sell them at a good price Cool

Reviving this thread, as I'm thinking about switching from an inline to an in-tank pump.

Two questions...
- Noise - I'm hoping that the submersible pump would be significantly quieter than the one under the sink. Is it the case?
- waterproofness... I haven't used the water system in my van yet, and so I'm unsure how the filling work - in particular how "it's full" works. I know it overflows from the outside, but the question is - will it overflow inside first if the cap isn't in place and tight. Measuring the height of both, it seems really close. Switching pump type would mean maing holes in the cap or the tank itself, and I want to know how good the seals need to be.

Jedi, if you happen to read this, do you have pictures of your conversion you can share?

Thanks,

JMR

(No pic of my setup, only found this one for the in-tank kind)
