First of all how do I begin looking for a course to re-do them. I live in Hertfordshire, England, so if anyone knows of any courses around please let me know. Also I want to be a nurse or midwife. So I want to know what GCSEs would look better when going to do my A-levels. missed most of my gcses due to being in hospital, failed everything except english and science which i got Bs on. I went to college for a while but it wasnt for me so i quit. Im now at University doing my second year for Veterinary training, because of the access course.
The pipe has a slightly larger id measuring in at almost 1 5/8-inces. This rule applies to steel and PVC pipe. The OD of 1/2-inch galvanized pipe is about 7/8-inch and so is 1/2-inch PVC. 3/4-inch pipe measures 1-1/16 inches, 1-inch measures 1 5/16 inches and 1 1/4 inches measures 1 5/8 inches. These same rules apply to rigid copper plumbing.
You can also use brass compression fittings on PVC pipe, as long as you use a Delrin, (plastic), ferrule under the compression nut.Just replace the brass ferrule with the plastic unit and it will tighten down fine. Done it many times. brass compression fitting will work on pvc pipe. But if your working with pvc just buy a short peice of pvc pipe and 2 couplers and splice it back together.
