Thermostatic Mixing Valves

Eire flag
Galway, √Čire
We were requested to undertake the inspection of a university accommodation at this location. The site consisted of a number of accomodation blocks of several floors and all the acommodation was en-suite.

The flats had been troubled with faulty valves from commissioning onwards. The initial problem was thought to be caused by detritus within the pipe system but even after a thorough cleaning the problems with over-temperature persisted and there was a danger of scalding. RAH Consultancy spent several days examining the system on site and stripping and inspecting a number of the valves. It was discovered that several valves were damaged internally. The cause of the damage appeared to be due to forces exerted during the valves normal operational use.

A group of valves were selected at random and were subjected to a range of laboratory tests under the supervision of RAH Consultancy. The results of the site inspection and testing led us to recommend in our report that these valves were ineffective in the prevention of scalding and required replacement as soon as could be arranged.

Legionella Death

Egypt flag

Sharm El Sheikh, Egypt

We were approached by a Northern Solicitors with regard to the death of a visitor to a hotel in the above resort who had contracted Legionnaire’s Disease. We were responsible for the examination of all the files and records regarding temperature control of the hot & cold water systems. We reviewed the European Guidelines on the control of travel associated Legionnaire’s Disease and the guidelines from the UK, America and Australia so as to understand if the control measures within hot climates differed from those in European countries. The examination produced no evidence of differing methods of control but the review of the records from site showed in our view serious areas of concern.

After serious talks with the opposing expert the Hotels Counsel conceded the case.

Invalid Bathing Equipment

We were involved by a customer of the Manufacturer in helping them to design the Back Flow Prevention Devices for Invalid Baths. This type of equipment has a high level of risk of pollution from the water in them, so British Regulations require a high level of safety to prevent the supply in a building from being polluted. RAH Consultancy designed a Back Flow Prevention Device specifically for use with these Baths. They then liaised with the Water Undertakings and a test house so as to get these devices successfully approved.
