Helping to make Hospitals a safer environment
The healthcare sector is one of the most challenging environments facing the specifying professional. Issues of hygiene and flexibility are as important as product quality and durability. Stevens Services offer a wide range of Twyford’s healthcare product range has been specifically designed following extensive research into the needs of healthcare managers and specifying professionals. This is a product range that combines innovation with practical attention to detail giving specifiers the total plumbing solution across all sectors of the healthcare market. Twyford leads the market with products that enable healthcare managers to provide a safer environment for staff, patients and the general public.
Achieving above the national standards
The Healthcare environment is, rightly, a highly regulated one. Twyford have responded to this challenge by investing heavily in a programme of continuous product development and innovation. This programme means that Twyford’s healthcare products meet and in many cases exceed the national standards covering healthcare institutions. From compliance with Health Technical Memorandum 64, which provides guidance on the design, application and specification of sanitary assemblies in health buildings to TMV3 and the new Water Regulations, specifying professionals can be sure that Twyford’s healthcare product range exceeds national stand
Government initiatives, new NHS regulations and increased public awareness of issues such as MRSA have increased the demand for fully compliant, tested and proven solutions.
To enable you to specify with confidence our technical guide Healthcare has been updated to include all the recent revisions to the Health Technical Memorandum for sanitary assemblies:
HTM 64 – third edition February 2006.
These include:
- Mixer taps with horizontal spouts and integral thermostatic valves
- Concealed back outlet basins for clinical areas
- The use of Rimless only WC’s
As you would expect, Stevens Services continually develop products to meet and exceed the requirement of current NHS Estates guidelines and together are the only leading suppliers who can offer a fully integrated solution to meet the new standard.
As well as HTM 64 it is important that any units supplied also comply with other relevant standards and guidance:
HTM 64 Sanitary assemblies
HTM 2027 Hot and cold water supply, storage and mains services
HTM 68 Duct and panel assemblies
HFN 30 Infection control in the build environment
Hospital Scrubrooms
Cleaning and disinfection
Components should be easy to clean. There should be no inaccessible recesses, rough surfaces or connections, projections, sharp edges, unnecessary joints or exposed threads etc which may retain
dirt, snag cleaners’ hands or equipment, or be difficult to reach. Hospital cleaning policies should ensure that care is exercised in cleaning sanitary assemblies, particularly those that are new. The manufacturer’s instructions should be referred to (see also the
‘NHS healthcare cleaning manual’, Department of Health, 2004).
To avoid damaging surfaces, only approved cleaning cloths, neutral detergent solutions and cream cleansers should be used. Materials such as scouring powders and abrasive pastes and pads can
cause irreparable damage and should be avoided. Abrasive scouring powders can cause considerable damage by removing glaze, and should be avoided.
A descaling fluid should be used to remove lime deposits in WCs and other appliances.
HTM 64: Sanitary assemblies
Scrub-up trough assemblies for use in connection with surgical washing of forearms and hands
The typical assembly requirements are:
1. Hospital pattern scrub-up trough.
2. Washing under running water (therefore no plug).
3. Hospital pattern (lever-action) tap(s) or automatically by sensor to avoid contamination.
4. Open nozzle and flow straightener with minimal restriction.
5. Water temperature should be controlled via integral thermostat.
6. Connecting to concealed services.
The point of discharge relative to front rim of trough is critical to ensure:
- that there is no water discharge/spillage outside trough;
- that water falls onto inclined surface of trough;
- that users are able to operate lever/s;
- that there is sufficient space for users to wash their hands and forearms under falling water.

Design and specification notes
Scrub-up troughs
Scrub-up troughs should be provided to enable one or more surgeons and nurses to scrub their hands and forearms.
Troughs should be wall-hung and fitted with a single waste outlet.
Taps should be wall-mounted and deliver safe, thermostatically (TMV3 D08) controlled hot water. A scrub-up trough assembly is illustrated above
Sensor-controlled fittings are ideally suited to control the flow of water at scrub-up troughs and can offer the additional benefit of controlled run times. The relationship between the taps and the
trough is critical in order to avoid splashing.
Taps
NOTE: Swan-neck outlets should be avoided, as recommended by Health Facilities Note 30 – ‘Infection control in the built environment’. Therefore, in existing facilities, when such an outlet has become damaged and is due for repair, this guidance recommends that it be completely replaced by an appropriate, alternative component described in this section.
