Electric shower problem

[rimexboy]

mmm i know its nothing to do with paving but the guys on here will know ...lol

well my electric shower seams to be getting less and less preasure, i thought it was the shower head so changed it for a spare i had but its still very slow and low preasure,

So i guess that the inside of the shower is scaled up with lime scale...

is their any way i can sort this or do i just throw it away and get another one..

its an aqalisa 10.5kw

thanks simon

hmmm
aqualisa is a good make but if you live in a hard water area eventually it will fur up
have you got one of those chalk interceptors thingymijobs on the cold feed?
might be as well to replace and use of those

Are you sure it's not the mains pressure that has dropped?
My brother in law had problems with an electric shower, turned out to be a pressure drop after he had a water softener installed (salt type)
It was enough to cause the problem but not that noticeable on the rest of the plumbing.
How's the pressure on your cold tap in the kitchen?

LLL no filter on the cold feed into the house.

Pressure is great here.

I've got a bad feeling its all lime-scaled up inside...

I think a filter is needed what's the best option and can you fit one onto plastic pipe?

Thanks Simon

The element may be scaled up if its a few years old.
Most bits can be removed and soaked in a descaler or cilit bang etc.
Sometimes it will trip the electrics when it get really bad.

[rimexboy]

Checked the filter all clear,

So decided to remove all the shower and leave to soak in some of this over night



This was a full bottle


Thanks Simon

we have one of those 6 inch wide drench shower heads and the missus removes it and soaks it in mr muscle descaler every 2 months

put it back today does not seam much diffrence at all .... any ideas

I doubt if the shower is at fault and you reckon the mains pressure is good.

So perhaps it's just because winter has arrived and the mains water is colder

I've found this with instantaneous showers. The colder the water in means the more you have to turn the heat control up, which in turns restricts the flow to get the required temperature.
So in winter to achieve a hot shower you have to put with a less powerful shower.
We still have an instantaneous shower plumbed in over our bath upstairs but it doesn't get used since we had a gravity fed shower off the central heating put in on the ground floor.

Edit
Just thought if the element isn't heating up as well as it should then you'd get the same problem.
You'd have to turn up the heat which in turns restrict the flow.
So perhaps the shower is faulty after all.

we had a similar problem with our old aqua the water would just trickle out it ended being the pressure relief valve was about a 20 quid fix cant remember what model ours was but may be a similar fault on yours
so might be worth doing a model search with similar faults

[rimexboy]

Mmm yer I am with you about the winter months the water is a lot colder so needs more heating but its never been quite like this I have to say.

I will look into the pressure release valve thanks for the pointer I will keep you posted guys

Thanks Simon

[rimexboy]

Well today I decided to bite the bullet and buy a new part, but aqualisa only sell the complete insides called the engine at a cost of £125.00.

It should be with me tomorrow they say.


Thanks Simon

[rimexboy]

Well I got this today



But have been out since 6am and just got in from work at 7pm, traffic meltdown round here, I will try and fit it tomorrow as I've had enough for one day...

Lazy so and so lol

Thanks Simon

[rimexboy]

Fitted the above today and all ok, I will keep the old one and try and descale it laters

Thanks Simon
