I found this at Wylam. I wonder what this is for? Maybe to weigh rocks.
I order hose to replace all low pressure. I had way to many problem with brittle old hose.
I also had a swivel break. A swivel saver break.
Then my high pressure soap was not working in one of my bays. I called Greg and he instructed me to turn down the water pressure and I would create a suction that would clean out the line. He was correct again and after runing with low water it started to work again.
But while I was in the proccess of fixing this problem. I broke the insulated lance. I had a band holding the high pressure on and it shot out of the holder.
