Hello,

I have a 199,000 btu on demand water heater to install in place of a standard tank heater. I'm going to put this heater in the attic right above the existing heater. The main gas line that feeds the existing heater is 1" and it tees off to 1/2" to the existing water heater. The on demand heater requires a 3/4 line. My question is can I put a 1/2" to 3/4" adapter on that tee then go to a 3/4" line without loosing too much pressure? The reason is removing that tee would be a HUGE pain in the butt so if I don't have to that much better!

Thanks

Dave

YOU are far better off hiring a LMP

You cant reduce and then increase the sizing of the gas line...."pressure" is not the issue it is the "volume" of gas that is critical. I srongly suggest having the unit professionally installed as most do-it-your-

selfers not only under-size the gas but do not install the appropriate combustion vent (most use the existing). Check local codes and pull a permit.

Unless you are certified to install gas lines, you better hire this done. I have been around the LPGas industry for years and have seen WAY TOO MANY accidents waiting to happen! Best pay the price and hire it right! But, if you insist on DIY on this, at least get a qualified person to pressure test your system before you fire it up again (pardon the pun).
