    Recommend a path to replace water filter / softener

    ok. Some clarification. The plumber used a kit, not strips, but again, it's either limited or a parlor trick. The ppm was 1.45 (but that's from the water company, not my faucet. Yes, the resin or media is likely worn out (7 years), but we had water issues almost from the start of that...

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    The current softener is taking hardness from 12 to 1, so that seems to be working. It's iron and then whatever minerals that cause clouding of glasses and white around the faucets that need to be addressed. The plumber insists that this 32K unit will resolve all of that. He did test the...

    Recommend a path to replace water filter / softener

    I had another post, where I had my tankless Navien repaired, and the topic of my water softener arose. Though not the reason for reduction of hot water, the Navien's Heat Exchanger Outlet Pipe rotted two tiny holes in 7 years. Both mostly self-clotted with sediment. Anyway, we have a...

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    Tap Score sells a kit for $180 or $290. I assume that includes shipping, testing, etc. The $290 - Ideal baseline for testing tap water provided by a local water utility–including metals, minerals, and chlorine-related byproducts. I'll keep looking

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    I always felt like anything they provided suited them, more than me. They published a report in January, showing results below. I assumed Range is what's acceptable: Average RANGE - Chlorine 1.21 1.08-1.37 - Nitrate 1.46 0 - 2.8 There's many others, but the report shows...

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    "he" is the plumber, who works for a fairly large local outfit. I like his demeanor, etc., but am always leery of a "sales pitch". I might contact another for estimate, but good luck getting someone to show up. We'll see.

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    Now I am concerned. He's stating that orange is chlorine, but everything I read says it's iron. I'm pressing for clarification, before moving forward. I have some time.

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    Not well water. Public water and it's notoriously bad where we are. Yes, we have a softener, which is bringing a public hardness of 12 down to 1. Thanks for saying orange is not Chlorine. I might have misunderstood him, but I sent him an email asking for clarification on what exactly...

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    Good point. When he left, I told him we'd wait until September, partly because I need to sort this out. He proposed a two stage filter. The first stage is a carbon filter, which removes chlorine, tastes and odors. The second stage softens water. Chlorine is leaving the orange...

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    I'm more than open to no spending thousands here. What make/model filter? We've had an Everpure H-300-NXT, dedicated to our fridge only, and it's not doing anything. The drip tray where we get water from our fridge looks like it's covered in battery acid. Cleaning it daily has almost...

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    Check valve went bad. Mostly the "O" ring disintegrated. The water is taking its toll, not only on the valve, but it created two holes in the heater exchange pipe, which actually self-clotted with sediment. I can see it on the front of pipe and fell it down where the leak is. All of...

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    Thanks. I am, and believe I do. They're sending a master plumber today and he handles all of their Navien. The woman I spoke with said it's a great product, and has few issues, but tankless are a bit unique to service. I need to discuss replacing the other water filter I have, possibly...

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    thanks. It was the page # tripping me to check GPM. My manual doesn't match the online manual you sent, so I used yours. Resting, the unit reads .6GPM. Running hot water at the sink, the display reads 4.2gpm. The sink will fill a gallon in 1 minute.

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    Damn! $300 for their Master Plumber to show up and diagnose. Tankless are more complicated, blah, blah. Then an estimate for parts/repair. IDK. I'm thinking due to neglect, having them give the entire unit a once over isn't a bad idea. But, if it's just the pipe, I could replace it...

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    Thanks. I did the flush a few months ago (successful) and yesterday (unsuccessful). Understood on the finickyness. I'm more concerned it will get worse, as I'm trying to sort it out. What about the water dripping from the Heat Exchange Outlet pipe? Certainly that's a hairline crack...

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    Navien tech support helped somewhat. I had already performed any diagnostics they're willing to walk a homeowner through. They said I need to have a certified tech call back. I was able to identify the tube as a Heat Exchange Outlet Pipe, but Navien was able to provide the actual part...

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    How do I time a filling? As far as the bad gas valve, the water drips right where I'm pointing (actually have a video). You're saying that silver pipe is the heat exchanger, correct? The water drips from the bottom, possibly a hairline crack. I don't see any evidence of water above it...

    Diagnose Tankless water heater. Hot but not enough. Tiny leak

    Absolutely The only changes at my house, around the time this began, I started used the hose out back, because our grass is dying. The valve to that faucet has always been on, so nothing new really. Just that I used it a few times. I can't think of anything else. Also, it maintains...
