Then The Sun Shone

The rain last night was very heavy and the field flooded. The horses were trapped in a far corner of the field when the sun broke through the mist.

We got a call last night to tell us that the boiler contractor would in fact call today. He came. He says it isn't the boiler. 

After a lot of fiddling Hubby has managed to get it working, for now. Will it work tomorrow?
