Pump and Dual Shower Issue

[jaydebruyne]

I went to a property yesterday..

They have 2 bathrooms (1 has a concealed valve shower, the other a bath/shower mixer tap). Both are fed by a 3 bar negative head pump.

Both work fine independently but when you run both at the same time, the shower furthest away takes the flow leaving the shower closest to the pump dribbling...

Just need some advice on possible reasons and solutions.

Pump on it's way out? Run a dedicated pump for each shower?

Cheers in advance

Is it a monsoon or a shower mate?

 

[jaydebruyne]

Not sure, I didn't check :/ It looks more like a monsoon though than a showermate I think.. *swear word goes here*

 

[Neil K]

Sorry scratch that, I reckon it's a monsoon. I'd start looking at how the one performing poorly, the nearest you say, is piped.

 

[jaydebruyne]

It's 15mm teed off from a 22mm hep pipe.

Run some 22mm then. And see how much storage you have in the loft

 

[jaydebruyne]

Storage isn't massive.. It sits behind the shower just above the cylinder

 

[Neil K]

Rerun problem mixer in 22mm. Is it the bath or the shower that's problematic? Check all ISO valves and filters including those on the pump. When I say storage, how big are the tank/tanks in the loft?

Turns out that the problem mixer tap wasn't opening fully.. Fixed the tap and problem was solved
