Installed new tankless water heater with a complete re pipe job. Swapped out cpvc, and a 50 gallon tank for a Rheem 199,000btu tankless with pex viega manifold, with bluefin pex and bluefin poly fittings. The pex is ran in home run fashion off the manifold. Off the water heater we go to copper for about 5 feet on both cold and hot witch then transitions to pex. There is a recirculatio system installed for this we have 3/4 pex ran around the basement in almost a big You connecting to every hot line with a 3/4x1/2x3/4 T. So now that you have an understanding of the system the hot water side has a pex smell to it, atleast to me I believe it’s a pex smell, one person said maybe a burning smell, the cold side has no smell or odor... has anyone ever experienced this... I believe it has something to do with the tankless heater?
