Navien told me: 5% household vinegar ok, pump should be very low power, can be 1/4 to 1/8hp. I had heard / read 1/6. Mine is 1/3 but I think I can make it weaker with a rheostat / speed control you’d hook up to a power tool.

So I took my shot. A failed flow sensor often causes unreliable domestic hot. Seemed fixed for a few days after I replaced (cheap on both part and my DIY time). Before going to the 3-way valve (above my pay grade!) would 5+ years of no de-scaling cause this? I have to de-scale and especially...

Not mine. No yearly maintenance. Maybe 7 years old. When I did the work yesterday I cleaned the debris trap (some silt!), air intake (nearly fine), water intake screen (nearly fine). I’m going to de-scale once I get some confirmation on the max HP transfer / utility pump I can use (have a...

I have an NCB-240E combi whose domestic hot is flaky (at best now, cold showers abound). Heating seems ok. I’ve seen on other Navien units that intermittent domestic hot could be fixed easily / cheaply with a replacement check valve. Am I right that on this unit it’s instead of the check valve...

Got it. I thought we were looking for siphoning evidence that water seal was breaking as opposed to gas muscling its way into the bowl (same gas result either way I assume).

Thx for all the detail and I think I follow. I happen to have such tubing because I’m a pack rat and will keep things that I might use once in the next quarter century. One question re: If there is vacuum in the drain air, the water level in the tubing would drop relative to the level of the...

Refills and holds ok. Sewer. In a heavy wind I will see SOME motion on the bowl water surface but never have I seen a siphon where the level drops say 3” to the gurgle point.

(This isn’t just toilet related, so posting here.) I’m half expecting some of you to tell me I’m nuts but I’ll tell you anyway. I have a downstairs (ground level) toilet. If I close the seat cover say overnight and open it: pronounced sewer gas. If somebody right above upstairs showers...

Well I took out the filter by connecting the feed to the output via a john guest union coupler. Flow rate was maybe 3% better, so seems like parallel filters is a non-starter.

Sewer gas odor caused by an evaporated trap in a rarely used drain (floor drain, guest shower...).

I've seen discussions / blogs about doing parallel filter installs for whole-house filtration but nothing on doing it for a single-point solution (though I think GE makes a "dual-flow" single stage filter that does just this). I have a water dispenser faucet with a 1/4" connect. Based on...
