Upgrading from Truma Ultraflow inlet and manual pressure switch

First time poster!

I have a 2019 Adria Isonzo which is lovely but as always there are some things you wish were different.

At present it has the standard (fairly inflexible) Truma pump assembly, Ultraflow inlet and manual pressure switch.

We nearly always run on battery, hook up is extremely rare for us.

I'd therefore like to both change our pump assembly to the Whale one with a Truma connector, but I'd also like to get a smart pressure switch to cope with voltage changes. All I've found online is people going either fully Truma from pump through inlet into switch, or the same for Whale. Given I'd be after a Whale pump but Truma inlet I'm unsure how to achieve this.

Any advice appreciated, I can't imagine I'm the first to ask this but sadly my searching has failed me!
 
I am seriously untechnical and may be totally misunderstanding your question but I believe you can get an adapter to connect a whale pump to a Truma inlet. I seem to think that we have had one at some stage of the game.
Welcome to the forum. I am sure that someone will come up with a better answer than mine.

You can get the inlet, I'm just trying to avoid changing absolutely everything. Unless the answer is that I should change everything!
 
My advice would be not to change to the "smart" pressure switch.
A lot of people have had problems with them and reverted to manual adjusters and the occasional need to adjust it.
 
The "intelligent" switch is rubbish and really not worth having.
After two attempts I dumped mine and went back to the whale dumb switch. I get no problems with it failing to work, never have to adjust it and I never use EHU to charge the battery.
The reason it works is that I fitted a LifePo4 battery and the voltage is stable rather than constantly decreasing as with an LA battery.
 
I just changed a client's Truma inlet for a whale types as he has managed to break both the 'pistol' grip on the external pump and the inlet housing a couple of times over the years . I had to increase the size of the hole in the side of the caravan as the rear of the whale inlet housing is bigger than the Truma and protrudes into the caravan. I marked out the size of the whale inlet fitting and added 3mm for clearance and used a multitool to cut out the hole.
On the outside, the 'face' of the Truma fitting is actually wider than the whale and two screw holes are left exposed , so I countersunk the aluminium skin and fitted two small S/S CSK self tappers covered in white soudal fix all adhesive/sealant. As the others have said stay away from the whale 'intelligent' pressure switch , it's not that intelligent and only works works with a specific type of water pump . A standard Sealed lead acid battery goes from 12.7 fully charged ( offline ) down to 12.0 flat so the voltage variation isn't that great and if on solar power the voltage can be as high as 14.2V , which IMO is a bonus.
