Water Pressure Hansgrohe Issue

Hi everyone,

I need some help regarding a new shower system that has just been fitted. I have recently had my bathroom made wheelchair accessible for my disability and I have a Hansgrohe Raindance overhead shower and handheld Hansgrohe Select with an iBox.

I had a close family member install the system as they have already installed one of these systems before.

I went to try it the other day and unfortunately on both options whether the overhead or handheld, the water just trickles out?

My father contacted the help centre for Hansgrohe and they said this is to do with the pressure and having a Combee boiler can limit the pressure.

This is very confusing as I was told when I bought the System that a Combee boiler would-be more than adequate to sustain the correct pressure.

15 mm pipes where used.

Is there anything anyone can suggest what could be the problem?

Also is there any recommendation for a plumber in the Hampshire area that can test water pressure and help the situation?

If anyone needs any more information I will try to be as specific as possible

All the best

Lee

 

Just bumping the post for Lee.

Anybody around Hampshire willing to test the water pressure?

 

Never seen a Hans Grove system fitted to a combined boiler any time we ever fitted they always required 3/4 inch independent hot and cold supply's to a twin impeller pump and then to shower check with them what they recommend for your type of shower
