Salamander shower pump

[Alg123]

Hello,
I am in a rented property and have a mixer shower which has had a Salamander pumped shower system CT55+ single fitted before I moved in to help with the water pressure.
I have yet to use the shower as all the hot water is pumped out first and is scalding hot and within 1 min the shower goes back to cold. We have tried having the cold tap on first then adding in the hot but the pump seems to over power it and only the hot water comes through. An electrician reduced the pressure of the pump but this has made no difference.
No one seems to be able to tell us why it is happening or give a solution.

Thanks.

Good question, the pump, plumbing off the top of the hot water cylinder and anything else you think might be relevant/attractive.

Is the cold water tank fed too and is it a manual mixer?

An electrician reduced the pump pressure? Why an electrician and how did he do that? Unless he has reduced the voltage to the pump through some form of rheostat?

Hi,
here are two pictures showing how the pump is connected to the tank, don't know exactly what I have but I'm sure you can see from the pictures.

The mixer is manual through the taps on the bath. The electrician was from a company which 'manages' the house kind of they come and do odd jobs he was fitting my oven today and was told to look at our shower as well. not sure what he did just told me the pressure was less so would help.

Jesus thats rough very much doubt the shower will ever work properly as the cold isint pumped (probably off the mains) and the pipework needs doing properly, apart from that its fine.

Oh mammy daddy... I can see what the electricians done, he's run some earth insulating tape to keep the pipes steady

Seriously tho, as Picasso says, that's an horses ass of a job I'm afraid to say. Maybe it was the electrician has installed it and he should stick to electrics, even then I'd question his electrics too if that's the power cable for the pump that's stretched taught. Lucky if the shower will ever work properly set up like that. It looks as if it pumps every hot water outlet too unless there's another T further up on the vent pipe
