Mira Sport Shower.

The incoming mains water filter has to be changed on this shower very often, or the heat regulation goes wonky. My old shower worked perfectly for years and didn't have a filter so far as I know. I'm thinking of getting rid of the filter altogether. Any advice from plumbers out there?

I would be more concerned as to why the filter bungs up quite so often. It's not a common problem.
It may be reckless to suggest you throw the filter away and not use one at all. I'd be more inclined to fit an inline filter in the water feed to the shower first.
I would also investigate the shower itself for anything else that may be affecting the heat control.

In this case I think a call to Mira would be well worth it. Their Tech. Help has always been one of the best.

Thanks Builder, you're quite right, that's the component I have to clean or change. Difficult to fit an online filter, so I'll just have to soldier on. The stuff the filter picks up looks like very fine sand. Neither Mira Tech nor our local Water Authority can account for it.

Thanks, Greenrook.
If you could consider an inline filter, it needn't necessarily be near the shower. It only needs to be in the mains feed somewhere.

Good luck anyway.
