Water pressure & shower help pls!

[Pilatesteacheruk]

We have a ground floor maisonette which has a water tank in the cupboard and header tank just above (I think) so pressure low anyway. The flat is all electric so no combi boiler or anything. The shower is an electric shower but the water comes out in just a dribble :( Does anyone know the best solution for this please? I'm going to get a plumber but would like some ideas as well!
In case @pigletjohn Sees this, I think the tank is light green! TIA

Are your tanks for hot orcold water?
Electric showers run off the cold water.

From our investigations yesterday:
Unscrew the shower head. Run the shower. If more water comes out, your shower head is blocked. Descale or replace.

If still no water, unscrew the hose where it comes out of the shower unit. Run shower. If water flow improves, replace the hose.

Then we moved onto running it on full cold for 2 mins, then upto full. At this point a massive amount of scale came out - but Google "no water from my make shower" to see if this is recommended for you.

We have a pump to boost to water pressure for our electric shower. It works really well but the downside is the noise it makes.

Thanks both. I think it's a hot water tank but no idea tbh! Will try descaling.
I didn't think you could fit a pump to an electric shower but will see what the plumber says!

An electric shower should be fed from the incoming watermain at high pressure (not the tank).

Is it?

Compare the pressure to the cold tap at your kitchen sink. Put your thumb over the spout and turn it on. What happens?

Now try the same with your cold bath tap and the shower hose (unscrew the head)

Thank you @PigletJohn only just got the flat so not sure how the shower was installed. Will check and report back later thank you

You can get an accumulator which may help.

Your thumb will tell you.
