why does the prd on trition shower keep blowing out?

[jackflash87]

Hi, Replaced a worn out trition 300ti shower for a trition belize shower 6 weeks ago and after 3 weeks i got a call saying the pressure relief device has operated.
I replaced the pressure relief device and it has lasted another 3 weeks untill i've had another call today informing me that it's happened again.

What is likely to cause this problem? what can i check?

a brand new shower head was installed with the shower.

Any help much appreciated.

either the shower head is blocked or the wrong type or you have lime scale issues

kink in the hose or pressure to shower to high. how come he types so fast , still my answers were different so now you have 4 choices to choose from

when was the new shower head installed ? was it properly comissioned ? ie read the instructions in the book ?

 

[on31ll]

sorry should say did the shower head come with the shower or if it a different shower head ?

Yes shower head came with the shower. Would a high water pressure cause it? is it common to install a pressure reducing valve to a shower supply. I'd of thought the same problem would have happened with the old shower though.

If its an adjustable type maybe shuts off (blocks) in between settings
or someone blocking head ?

yea, blocking the spray head would cause this, it can be a particular problem with some highly sexed women, just use your imagination if you dont know what i'm on about :blush2:

check the cold mains pressure, did you fit the ring to stop the head being immersed in the bath water? ask the customer what they were doing when it happend?

PRV on a shower? Is this for power showers or normal electric showers?
