Why don't you have a quick google before making stupid comments?
So am I mate what a joke! Another local windie who has helped me in the past hasTook away the old booster pump to have a look at it see if he can fix it. My uncles workers some how dragged resin through 4 of his sureflo pumps in one day and stopped them pumping, me and a few others lent him spaires to see him threw... The same lad stripped all the pumps down and fixed them all! We are all suppose to be "rival business's" haha
