New and wanting help. Air in the system?

[Francisco Barros]

Hi
Got a new house and has a power shower fitted.

A few weeks after moving in the shower started to struggle, like water wasn’t coming through.
Got a “Triton power shower” but the problem still there. Sometimes worked a little better and sometimes didn’t but always struggling , sounded like an engine when stationary but still pressing on the pedal.

Got a plumber and he fitted a valve in the loft to release the air.

Problem still there and he advise to replace the shower was it was faulty.

Got a new shower today and before I installed it done some tests:
- try to bleed the radiator in the bathroom that it’s connected to the hot water system (at least it’s what I think), no luck.
- check the water coming to the shower pipes without anything attached and clearly can be seen struggling.
- used the trick to block the hot water in the kitchen and while blocked open the cold, no luck.

Fitted the new shower but still doesn’t work.
Tried to let it run without the shower head and it does run (struggles) but 10 minutes later wife goes to have shower and doesn’t work, goes dry.

I have water tank in the loft that feed the hot water tank, the locking thing works.
In the kitchen there is a boiler that heats the water and does the radiators.

It doesn’t have a Surrey or Sussex flange but after discussing it with the plumber he says the way it is should work.

Any help would be welcome as I am relying on a jug for shower as the other shower in the bath has no pressure.

Anything else done in the house in these few weeks?

Can we double check , the shower is defo a power shower . ie it has an internal pump ? And uses tank fed cold and hot water from the cylinder.

I installed a nest and have the tank on a schedule to come on twice a day. Also the electric back up heating element it’s always off.
Don’t believe they are related.

Yes correct, no heating element just the pump. Cold from the tank in the loft and and hot from the cylinder T on the top/ left .

When I turn the cold water feed from the tank in the loft to the the cylinder off, there is no water coming out of the taps. Is this a normal behaviour?

 

[townfanjon]

Ideally your taps should be “mains “ fed but some are tank fed, does this turn the cold to the shower off ?

Don’t know what you mean by that? They are mains as they got pressure. My finger doesn’t stop the flow , where as in the hot does .

 

[townfanjon]

Not sure myself pal , a power shower should not be mains fed , it should be fed by a tank ( cold from tank in loft , hot by the cylinder )

It is being fed by the tank and not mains. And hot water from cylinder.

Can you confirm that the cold to the shower is a separate pipe all the way to the cylinder?
Also, you say there is no flange to the cylinder. You do, however, have a separate pipe all the way from the shower to the cylinder for the hot? And how does this connect to the cylinder? Can you photo or sketch it for us?

Hot comes from the cylinder as seen on the photo. When in the loft, there is a cold feet that comes from the tank and runs parallel with the hot into the power shower.

It's pulling air in from that

Confused lol lol

 

[gmartine]

I'm confused, wtf is that cold water feed doing attached to the HW outlet of of the cylinder? DIY job?

 

[Francisco Barros]

When I mentioned mains, I was talking about about the taps and not the shower.

The shower is hot fed from that pipe on the left that comes off that T thing. And cold from the tank in the loft.

What cold the two pipes on the left are hot out and the one on the right feeds the tank with cold water.

Can you explain where the air it’s getting in ?

 

[ShaunCorbs]

Pulling in via the vent I think

 

[Francisco Barros]

Ok I think I am getting somewhere.
As do only thing that changed was the Nest and having a schedule to come on 6-7am and 17-18pm.

So yesterday set the boiler to always on 24hr ...
And the power shower worked again and this morning still working.

I am confused ‍♂️
Why the power shower only works when always It’s always on???

 

[gmartine]

Get a different plumber to have a look.
