The machine Alfie the plumber has hired looks like a Zimmer frame with a big pump bolted to it – a pump designed to blast water through our heating system at many times the pressure of the one in the boiler.
This is the latest intervention in our ongoing heating crisis, which has been going on since early January. The pump has already been replaced. The pipes have been injected with two different scouring chemicals. The whole system has been drained and refilled several times.
