When draining down, always count and record the number of rads you open. I've just worked in a very large house with 47 rads, missed the 2 in the walk in wardrobe, came back next day and had to get on with this:
Drawing and dining rooms, ceilings knackered. One sofa to recover, one large carpet to replace. Thank God for PubLib.
Worst day of my working life, the poor custards were very good about it when they came back from holiday Saturday morning. A real pride denter, stupid, avoidable mistake. I hope someone else can learn from it!
