will i get scalded

[wolfiehogan]

hi guys hopefully somebody can help and also hope i can explain my situaton properly
here it goes
i had to connect up a shower to day and also had do the plumbing of the shower to the wall.
the customer had taken down the old shower himself so i arrived plumbed and wired new shower. i then checked if it would work and it didn, here`s why
the old shower was a tank feed shower from the attic with its own internal pump and the new shower is a mains feed shower. i know how to change this though but here is my problem.
i was told with a mains feed shower if somebody uses a tap in the kitchen at the same time there is a possibility of the person in the shower gettin scalded/ as the element will be heating less water at that time.
is this true or what should i do thanks

you can't operate the mains-fed from a tank

you need the pumped shower


but you're right the mains fed are more prone to temperature change due to drop in water pressure on main

you can if i tee the pipe off before it goes in to the ball-cock but not sure what to do

will this drop in water pressure be enough to raise temp to hurt a child maybe or how dangerous is it

 

[wolfiehogan]

its a mains shower

 

[davelerave]

i understand your problem!
what's on the main-just the sink

the more stuff on the main the more the pressure (and temp)may fluctuate

a plumber will know more

i would try to replace' like for like' rather than alter plumbing -pumped is preferable IMO

the cut-out is designed to prevent scalding

in that case your not feeding from the tank your coming off the rising main which is pretty much the same as coming from tap pipe (in a direct system)

you could feed from the tank depending on the shower model and the elevation required (not recomended)

at a guess i would say if the shower starts to get hot most people have sense to move or adjust temp

 

[wolfiehogan]

does any body know what is the best way to find out how many taps are on the rising mains

 

[ezzzekiel]

either all cold or one in kitchen
turn off water, if it stops at all cold taps immediately its a direct system and fed from rising main, if they take time to run out then its an indirect system and fed from tank.

As above a toilets!!

Depends upon what type of electric shower you fit whether the water will get scalding hot or not, most showers are fitted with a pressure switch so that if the water pressure is below a certain value it will not switch on power to the heating elements also if pressure drops below this value then the heating elements are switched off.

This is why you don't fit the with the water supply from a tank.
