Tony - Too good not to share!!!!! IRISH MINISTRY OF WORKS SPECIFICATION FOR THE ORDERING OF PIPES ACCORDING TO CODE OF PRACTICE I/RISH PIP/ES 239/H44233S 1. All pipes are to be made of a long hole, surrounded by metal or plastic centred around the hole. 2. All pipes are to be hollow throughout the entire length. Do not use holes of a different length than the pipe 3. The ID (inside diameter) of the pipe must not exceed the OD (outside diameter) otherwise the hole will be on the outside. 4. All pipes longer than 1500 feet (483m) in length must have the words “long pipe” clearly painted on each end so that the contractor will know it is a long pipe. 5. Pipes longer than 2 miles (3,2km) in length must have the words “long pipe” clearly painted in the middle so that the contractor will not have to walk the entire length of the pipe to determine whether or not it is a long pipe. 6. All pipes over 6” (152mm) in diameter must have the words “large pipe” painted on it so that the contractor will not mistake it for a small pipe. 7. It must be clearly stipulated to the vendor whether a level, uphill or downhill pipe is required. If you use a downhill pipe for going uphill the water will flow the wrong way. 8. All couplings should have either right hand or left hand thread – never mix the threads otherwise as the coupling is screwed on the one pipe, it will fall off the other pipe.
