John Dirks Jr Posted June 30, 2014 Report Share Posted June 30, 2014 Since TPR piping is to be run full size for the entire length of the discharge pipe, wouldn't a Shark Bite coupling violate that rule since the coupling has reduced ID?

Jim Katen Posted June 30, 2014 Report Share Posted June 30, 2014 As long as the fitting is the same nominal dimension as the valve discharge connection, I don't believe that it's a real problem. Quote Link to comment Share on other sites More sharing options...

Tom Raymond Posted June 30, 2014 Report Share Posted June 30, 2014 Why do people make these? The big box stores sell prefabricated extension tubes in the same aisle as the tanks, and for about half the cost of that fitting. Quote Link to comment Share on other sites More sharing options...

He must have a long copper discharge tube there with elbows and angles, just in case a bit of water ever came out of the valve. [] That fitting would be a non-issue for me, but if there are more than 3 elbows, those would be restrictions. Quote Link to comment Share on other sites More sharing options...
Eric B Posted July 3, 2014 Report Share Posted July 3, 2014 The big box stores sell prefabricated extension tubes in the same aisle as the tanks, and for about half the cost of that fitting. The hardware stores sell all kinds of stuff that don't meet regulations or manufacturer specs. But they're not going to tell the consumer because it would cut into their revenues. I had an ACE store tell me they sell the clothes dryer vent diverts because people want them. They also acknowledged that the diverters are unsafe. Though the TPV extensions must be in metal pipe for our state the stores still sell the plastic ones. Quote Link to comment Share on other sites More sharing options...

Marc Posted July 4, 2014 Report Share Posted July 4, 2014 Standards like this one are often the answer HIs are looking for but they're so expensive. Plus, many are rewritten every several years, then you have to pay again. Code books I can afford but standards are just too much for a one-man business. Thanks to Garry.
