Immersion Hot Water

Your OSO electric hot water cylinder is located within the Airing cupboard of your apartment and comes with a 25 year manufacturers guarantee that is to be activated by the owner of the property.

Stop Cock

Each apartment is fitted with a stopcock to isolate the water supply fully to each apartment individual. These are located outside of each apartment main entrance door in the corridor area above the ceiling void. They are located here for ease of isolating water should an occupier not be available in the event of an emergency.

Isolation Valves

Each plumbed in fixture and fitting pipework within the apartment is fitted with isolation valves meaning that you can isolate the water supply to any fitting rather than turning the water off to the whole of your apartment via the stopcock. The isolation valves can be found for supply to the toilet, washbasin, sink and washing machine.

Please see the below photographs and guidance on how to isolate a water supply to a fitting within your apartment.

Waste Plumbing

Waste water from your kitchen and bathroom runs through the pipework directly into the drainage system. You are responsible for the maintenance of all the fittings and waste pipes within your apartment.

If you find that a sink, bath or shower is taking longer than normal to drain you can use a chemical drain cleaner which is readily available from all good DIY stores. Alternatively please seek professional advice.

You can prevent your sink and plug holes from becoming blocked by regularly cleaning them.


Please refrain from putting food waste, oils or fats into sinks as this may cause blockages. Do not dispose of anything other than toilet tissue in toilets, including nappies, wipes or sanitary items as the system is not designed to deal with such items and will result in an expensive blockage for which you will be liable.
