Suffering from pathetically poor water pressure. I have checked and verified the following:
The leisure battery shows a healthy 13.11 volts
I've tweaked the pressure switch up and down, followed the handbook to avoid "hunting" and got the pump switching off as specified when taps are closed
I've removed the stupid little filters in both bathroom and kitchen taps. I've replaced the rubber o rings on the connector which " plugs in" to the external caravan wall.
, Still I only get a dribble on both hot and cold systems. I've even tried new submersible pumps to no avail.
Any help would be greatly appreciated as I've run out of ideas.
have you tried connecting the water system directly, not via the aquaroll? if so is it still the same? when was the last time you put some puriclen thr the system? that should help clean out the pipes too
you connect it using either https://www.touringaccessories.com/product/whale-truma-ultraflow-mains-water-hook-up-adaptor-connector-em9433/ or the carver version depending on your caravan, now i know they are expensive and im not suggestng buying it just to check but maybe you could borrow one from someone to try when your next away in the caravan?
Silly question I know but you have closed the drain-off valve/s haven't you?
Check underneath the caravan to ensure the water is not being simply pumped out instead of going to the taps.

To be pedantic, what you are suffering is poor water FLOW which could be low pressure or a pipe blockage!
It seems that you may have sufficient pressure as the pressure switch is turning pump off OK when taps closed, which implies that the pump is OK especially as you've tried a different pump as well, and that any non-return valve is functioning (more on that later!) otherwise pump would kick back in once pressure leaked away.
The fact that both hot and cold water have bad flow, suggests problem lies early in the plumbing, with the feed before it splits to the boiler.
Couple of things seem worthy of further investigation, is the non return valve FULLY opening? The other thing to look at is the water connector housing and pipe immediately behind it, the external weather cover is largely cosmetic, it does little to stop bugs getting in, so possibility of a bug having nested in pipe and causing a blockage/obstruction.
With typical caravan plumbing, the joints are John Guest push fit, so it's a simple job to disconnect pipes. With an assistant to disconnect the pump QUICKLY on command, it's worth trying an open ended pipe run (obviously into a container!) starting as close to the water inlet as possible to see where the flow drops off, then you have isolated the pipe run where any obstruction may be. If an obstruction is found, then reverse flushing may clear it, or a simple new length of pipe.
Another possibility is low voltage to the actual pump electrical connectors (your battery may be sound and 13.11v is good), but have you checked voltage on pump connection terminals?), if the voltage is low, the pump will likely run, even build pressure on a system with taps closed, but may not produce normal flow.

It sounds like the water system isn't pressurising but it may help if you state what make of water inlet you have whether it's a Carver, Truma or Whale system as the Carver can be problematic in more ways than one.
