  • On the fly

    What do you think the limits are, in pipe size and pressure, that a threaded water main service valve inside a building can be changed on the fly?

    I would never even try it. The liability is too great.

        i've done it with angle stops and hose bibbs before.

        depending on the pipe size, and pressure. plus how wet you want to get and will the threads get damaged when the last thread is left hanging while unscrewing will determine your success or your insurance bill

        freezig is possible under the right conditions.

          I would never do a main water service valve on the fly, regardless if it was residential or commercial. I don't think my insurance company would like it either.

              I would never try it but...... ive been able to cram a Jet Sweat into a 1" copper pipe under 45psi. Two hosebibbs open to help relieve pressure. I was soaked but it was 90 degrees outside.

                If you're going to try it, make sure you have a friend film the event, and include the audio. Could make for an enjoyable u tube experience.

                    Ok, here were the conditions at the time:

                    -The 3/4" threaded ball valve was split, leaking,getting worse by the hour, and I was concerned about the valve rupturingovernight. 2 days for a street opening permit to close the corporation stop.

                    -60 psi, 3/4" K copper water main. Inside a 4"house trap pit with the handholes open. Ground floor warehouse,pit located next to a roll up door leading to thesidewalk.

                    -Threaded adapter at the water main, and a heavy c-clamp onhand to close the copper pipe if needed.

                    The procedure took less than 90 seconds. Too boring foryoutube.

                    I also enjoy an 8% discount on my insurance due to a lowexperience mod, and I have frozen many water mains. Could not do it here.

                    So why the condescending responses? Instead of posting picsof the science labs and radiant systems I completed, I decided to leave my egoat the door. I just wanted to converse openly with like minded pros. I haveread posts by others describing practices I would never condone, but I withheldjudgement.

                    I have a thick skin (I train in MMA), but this bothered me.I wish some had asked for clarification before going negative. I truly wish allof you the best,(especially Plumber Rick) and I liked reading past posts, butthis place is not for me.

                          In my experience the more important the need is the more problems one will experience in the process, (if you can shut off the water, you will have few problems, but if you can't and even tho you have done the process a thousand times with out problems, usually that is when the stuff hits the fan at the worst possible moment,

                          If there would have been indication that the building would not be flooded if the process was not as fast as desired, may have got some different responses,

                            Never done threaded. Done lots of propress. You need an extra set of hands though. Biggest I've done is 1-1/4" at 75PSI outside. We both got real wet. Cut it, slammed the valve on open, pressed and closed the valve.

                              ray, were you ever worried that the water blowing past the open pipe could wash out the o-ring while trying to slip the 1.25'' valve onto the open flowing pipe?

                              i'm glad it worked and this gives me more confidence when i need to try it myself.

                              best i remember doing is the time a 3/4'' copper pipe was crushed and spraying making it impossible to freeze. this was before propress. i managed to use a bolt cutter to pinch off the copper and stop the flow. this allowed me to freeze the copper, cut the copper round and make a soldered joint. shutting the water was never going to happen on this property.

                              rick.
