seen my first national company today as out in the sticks we do not get them. good bunch of chaps and very friendly but the poles they were using were out of the ark(probably made from the wood) and there was not a flow rate just a gush of water.
they said their boss was too tight to invest in good equipment which i cannot understand because of time saved etc.
Because hes not stupid, most staff just wreck equipment, I dont know how but they do, give them and expensive pole costing many humdreds and a cheap pole costing thirty pound, you can bet money they break the expensive one first, some is sods law, the other its not thiers so they simply dont care imo.
they earn more money with a higher flow of water as the job is done quicker, water is cheaper than time.
