Just a trickle from the tap

[NewForestKnight]

Hi. I only seem to get a slow trickle of water from my tap. I've been through similar threads but most seem to be in relation to complete non-function of the tap.

When I turn on the tap, I hear the pump whirr so that seems OK, but just a steady trickle comes out. Not even enough really for teeth brushing / hand washing.

I've topped up the fresh water tank, tried it with the filler cap off in case of airlock, even tried sucking really hard on the tap as suggested on a thread here incase of cavitation in the pump. All with no luck - any further suggestions? We're off on a longer trip shortly so would be good to get this sorted.

It's a simple system. Pump, pipe,tap.
The tap electrical connection works as pump starts.
If the tap was semi blocked one would expect a low volume high pressure jet not a trickle.
Pipe, twisted/compressed. Check pipe under sink attached to tap.
Next, more involved.
Open water tank top lid. Check pipe to pump is properly connected both ends.
Finally, pump. It may not be running at full speed due to age/ wear. New pump, or low voltage .
Back to tap. Disconnect electric plug from tap ( found wrapped in foam and pushed up on the R side of the sink bowl underneath- remove Cutlery draw for access ) now bridge the 2 contacts in the plug Not Connected to tap using a paperclip or wire. Open tap. Good flow? If so high resistance on tap switch. You can replace tap or try to disassemble and clean switch contacts.
If there is no change in flow Check voltage at pump connector using multimeter if less than 11volts then you need to start checking the wiring connectors back to the 5amp fuse under front passenger seat.

Thanks @WelshGas thats a comprehensive response! I'll work through those & see whats up.

Hi, did you get an answer to your problem? We have just set up on a site and the same is happening. We last used the van only 3 weeks ago.

Hi, did you find the issue with the tap flow? We’ve got the same. Just set up on a site and went to fill the kettle and it’s a dribble.

Tried sucking through the tap with the pump running, and with it stopped (disconnected the tap switch). It seems like there’s lots of air in the pipework. Still low flow from the tap.

Check the nozzle on the tap is clear and not scaled up with limescale (use vinegar to remove) or full of mildew type deposits

It’s okay. Also tried the shower attachment in the boot, it’s also trickling. It looks like the pump.

Anyone know if this is a warranty matter?

I’ve fixed the issue with help from members posts. The pump had fallen sideways so the discharge pipe wasn’t fully connected to the hose connection on the tank lid.

A small challenge getting into the tank, but that done, it was a 2 minute fix. I will look into getting a sprung hose clip to give some resistance so the hose doesn’t easily come from. Maybe someone knows where to buy stainless steel / non corroding ones ??
