Triton shower not working properly

[soccercelt]

Had a plumber install a new triton Alicante shower but it seems not to be working properly. The 1/2 inch pipe was taken of the mains (see pics) , down and under the floor then up the wall. Electric connected with right cable. We tried to commission the shower by turning it on cold then turning it up. There's a sound coming from the shower but nothing like what it should IMO. There's water flowing but nothing major. Does anyone know what the problem could be. Was it it for an hour but still the same as first tried it!

First pipe vomin from the mains is going to feed the gravity fed heating system fitted with an expansion vessel.

Does this type of triton have an electrical ribbon from the cover to the shower? Is it connected?

When you say "gravity fed heating system system fitted with expansion vessel"? Do you mean vented system converted to sealed! :s

Its gravity fed central heating heated by oil and there's an expansion vessel instead of small header tank.

Are you sure that it is plumbed into the mains, and not into the cylinder feed pipe coming from the hot water header tank? That would result in a very poor flow of water for an electric shower.

This is getting vfed from the black pipe feeding the heating system and cold water tank in Attic. I can see the cylinder feed pipe with a gate valve coming down the wall feeding the bottom of the cylinder.

not mains then, shower won't work properly

You have possibly connected into the cold feed to the cylinder from the header tank in the loft, gate valves are not used on mains water supply trace your pipe work again will not work as it is
