Burst pipe or water you cannot stop
Yes. Ring immediately — every minute of running water is damage you will pay to dry out.
Sewage backing up into the house
Yes. This is a health issue as well as a plumbing one, and it does not improve on its own.
No hot water, in winter, with kids in the house
Yes, we will treat it as one. In summer, with an adult household, it can usually wait until morning and cost you less.
A tap dripping, or a slow drain
No — and we will tell you so rather than charge an after-hours rate for it.
