is it possible to fit a outside tap with a tap lock

Yes you can buy an enclosure that you secure with a padlock, ask at any plumber merchants.

Any outside tap should have a gate valve inside the property enabling you to isolate the water supply at any time,therefore no need for a tap lock, hope this helps, Mark.

Hi I was in JDP plumbing supplies and they had a screw on lockable cap on a display for this exact purpose Pete.

Yes, the correct way would be to fit an isolater valve inside of the house, this is the cheapest way but also the correct way to isolate from frost or public abuse.

Hi Olagu. It is normal practice to fit an isolator valve somewhere insdie the property in order to shut off the supply to the external tap. This is primarily so that the outside tap can be serviced if required and to prevent freezing and subsequent bursts in winter. If this valve could be fitted in an easily accessible position, it would also function to stop unauthorised use. I would suggest fitting a ball valve (more reliable than a gate) with a handle rather than one which needs a screwdriver to operate. These can be bought at any plumbing supplier or DIY outlet.

Yes you are able to buy a outside tap that has a red leaver which will allow you to turn the water on and of but also allows you to put a padlock on it and also come with a check value so complies with water regulation

Any outside tap should have a non return built into the tap and an isolation valve inside the property to stop any pipes from freezing thorough the winter months enabling you to isolate the water supply at any time,therefore no need for a tap lock, Many thanks Harvey
