Please ask your customer:
- What has happened ?
- What works have we done? How have we caused the problem?
- What affect is this having on the customer?
- Details of any appliance affected?
- Is the internal stop tap working?
Did you know: The most common cause of internal issues following works is an air lock. Your customer may be able to solve this quickly themselves by turning the internal stop tap off and on again about 5 or 6 times. Remembering to leave the stop tap ¾ of the way open. If your customer or their plumber are willing to try this, it will rule out any airlocks
