At first, the water tank is not horizontal and the front of the tank is slightly raised due to the shape of the V-berth storage, but tank vent is on the lower side of the tank. That leads to an air pocket and we could not fill the whole tank (54 liters).
The second problem is that water pump. Under certain amount of water, it's unable to pump out the every lasts of the water, leaving around ~5 liters in the tank.

The third problem is the supply hose. It's going from port side and because it's just laying without proper installation, this "arrangement" creates puddles of the stinky water. Not even helping the winterizing process.

So the first step is to relocate the tank vent to the most top it could go. I simply used slightly modified plastic thru-hull near the edge of the tank.

Then routed a new vent hose on the top of V-berth storage and installed the new water pump Vetus WP1208.

During the electrical installation, I've found out another "bug". I know that the boat does not fully meets the marine standards for wiring, but this .... ??

| Shame on you Dalpol electrician! |
The water pump has a pressure switch which can be used later, when we would like to have a stern shower or something similar, however we have the faucets with the electrical switch already, so there is no need for it now.
And this is the final installation with the proper hose alignment allowing us to have more water on board :-)

The last benefit of this modification is that the output hose is now going to the top of the storage locker and not from the bellow as was originally installed, so when there will be some water ingress from the depth sounder, it will not flow around the whole hull and stays in the locker.
Updated 24.10.2016 - To prevent the frequent starts of the pump and to increase its service life, I've installed the small accumulator tank under the sink in the galley. It's connected directly to the hose which leads to the galley faucet.
