Gritty bits of scale from triton electric shower.

[Antonyhart]

Hi. I'm new to this forum so please bare with me. I was called to a job 2 days ago, bloke had alternating pressure/temperature on his tritton electic shower I took the head off and shook loads of sharp sand like bits of scale out. I ran the shower on/off slow/fast hot/cold for about ten mins. And must have got about half a cup of bits of scale out. It started to run a bit clearer so told the customer to try and use it over the next few days and see how it goes. I also showed him how I had 'flushed it out' so he could do it if it happened again. He called me today because he had lost pressure again. Exactly the same problem. I got probably another tablespoon of grity lime scale out again. where's it all coming from, surely the shower can produce it that quick. Is it a build up that has been disturbed and is now clearing. Has any1 experienced this. Whats the best cure. Shower is under a year old. Thanks ant

The heat exchanger is probably scaled up is my guess.
Hard water area? Shower being used excessively/too hot? You can clean a showerhead by tieing a bag filled with vinegar over it and letting it soak overnight.

Thanks for your reply. Yes hard water area. That's what I thought. But was wondering if it could clear itself out as there was a lot of scale coming out. I know scale is probably always being produced but surely not at the rate it was coming out. Also the head isn't scaled up as such it just had a lot of loose bits of scale that have come from heat exchanger.

Got a phone call today to say the shower was not staying hot for more than 10seconds now. He got another year out of it but think its now time to replace it.

Hi,

I have the exact same issue as is described here. We have an electric shower, Aquatronic 3 Ultra, downstairs (fitted with plastic pipes, not sure if this is relevant). I literally have to dismantle shower head every few days and there is enough grit/limescale/not sure what it is to fill at least one tablespoon. This has been going on ever since we moved in - around 4 years ago. Does anyone know what the cause of this might be?

Do we need a new shower? Or new pipes? Or something else?

Thanks!

Phil
