Tepid showers...

[Rob Sutherland]

Hi to everybody, it's my first time writing to this forum and I need some help please-bit of an odd one but I'm sure someone out there knows the answer!! We have a Worcester 24i and all was well until a friend who's a plumber fixed a dripping shower (on 2rd floor, terrace house-boiler feeds kitchen sink, bathroom on 1st floor with shower, sink and toilet and shower, toilet and sink on 2nd floor). Since then the we have limited hot water coming out of the showers and the hot tap on the 2nd floor (plenty of pressure) but we still have pipping hot water coming out of the kitchen sink and hot water basin tap in the 1st floor bathroom. At first the Plumber thought it was a blockage in the hot water pipe to the shower on the 1st floor but it was pretty clear, so he re-set the temperature on the shower but it made no difference, so he then thought it might be the thermostat in the shower, but as we now have luke warm water on the top floor I think it must be something to do with either the bolier or the hot water feed to the showers and hot water tap on the top floor (he said the bioler only has a single feed so it would affect all of the hot water). We're stumped and given the temperature outside we'd love to have hot showers again, so does anyone have any ideas please?

Sounds like you may have an airlock. Alternatively stuck check valve in one of the showers.

or blocked filters

Reminds me of a job last month -

Customer phones up about shower not working. Says that last year she called the person who installed it orignally about it making a lot of noise. They made a wooden box, sat the pump inside and packed it with glass fibre.

Predictably enough, it had subsequently overheated and burnt out the motor.

Tried a new one and showers were still feeble. One shower I could get at the back pipework, cleaned out the filters (full of debris) shower now working fine.

The other shower had been built into a drywall. No means of getting at the filters other than cutting a hole in the other side of the wall from the upstairs landing. Suggested doing so. making a plate and the customer hanging a picture over it sometime next year.

Well could be as simple as the flow rate is now to much going through boiler so can not heat up
Presume plumber friend isolated to fix dripping shower,when he has turned back on maybe turned on to much at valve under boiler ,turn valve down slightly under boiler were cold mains supply enters hopefully will correct siduation
