2 showers 2 different pressures

[S8wrd]

Though not shown in the picture there is a pump feeding 2 showers with one of the showers branching off to the left ,the pressure in this one is not as good as the shower fed by the vertical pipes... Could thus be due to the natural action of the pump pushing water pass the branch off ?[/img][youtube][/youtube]

More likely to be due to restriction from narrow bore isolation valves or blocked filters in the affected shower. Did the shower you are having problems with used to have better flow or have you always have a problem with this shower?

Changed to an overhead rain style shower and the pressure has greatly reduced......would going up to 22mm help ?

Does the pump kick in and stay on when you turn the shower on? I would check the shower filters and that the pump is suitable for the new head. It may be that you do not have sufficient height between the shower head and the water storage cistern. If so a negative pressure pump could be a solution.

Generally the pump will only kick in when the temperature is cold ....I think the new head is too much for the old pump as well as it has just started leaking on the cold outlet .....I'm going to change the pump on weekend and hopefully this will improve (techflow tp 60)
There's also 2 filters on the installed on the vertical pole feeding the handset and overhead disc which are brand new
Will going up to 22mm benefit ?

probably the pressure drop on the valve cartridges... are the two the same model?

Yes same model ....will take isolation valves off and let you know outcome
