Photos attached: There seems to be a fault through my shower floor and separation of the grout along those lines. Closest to the wall I know some water accumulates under delaminating tiles. I have cleaned off the "fault" line with CLR. Hoping to find a fix with out removing the entire floor. I...

When my Navien NPE 2401 tankless water heater is set to 120 degrees F I get 115 degrees at my farthest fixture. Set at 125 degrees I get 120 F at my farthest fixture. It there a way to calibreate the temp on these units-- I see nothing in the Manuals. Thanks

Navien NPE 240A— Navilink recirculation—some customer insights. I have had The Navien NPE240A for about two years now and the unit has worked flawlessly, but it has taken me a while to get my recirculation settings working and recirculation parameters dialed in. I thought I would share here...

I finally have my Navien NPE 240 A scheduling working, but I want to tweak the parameter settings to try and get the hottest water to my farthest fixture and keep it hot during the scheduled recirculation times. I want to tweak the Parameters a bit to minimize a cold water sandwich. Does anyone...

Tech support is not open yet: Just had installed a Navien 240a. Using the internal pump to set up an external re circulation line through the cold water system as return with a Grundfos comfort valve at the last fixture in the line. This seems relatively new for Navien and is in a recent...

I bought a steam generator for a steam shower that I am constructing. It sits in a "Smitty pan " for leakage or overflow that allows a 3/4 pvc outflow pipe. The only place I can drain this is into a nearby drain stack that the sink empties into. because pan should never have water in it I...

I am building a steam shower an have had to sort through a lot of conflicting information on the web. I know many like kerdi or nobleseal but the inside membranes seem like extra cost, more pieces or strips to leak and more work to install (two layers of thinset). I am looking for feedback...

My contractor left me with a 3" WC PVC rough in. The PVC pipe comes straight out of the cement slab and no space was left for an over the pipe closet flange. While inside the pipe 3" closet flanges are available people seem to discourage these because of the narrower diameter (2 11/16). I was...
