1. ### Measuring developed length and fixture units

Hmmm. Any idea why they picked 5'? 8' makes sense, based on the Fig 25 shown in Post #2 above; but 5'? That would allow about a 3/8" slope.

Perfect.Thanks.
3. ### Measuring developed length and fixture units

I'm converting from a tub/shower to a large (72" x 72") roll-in shower with 2 shower valves and heads -- one standup and one at a bench. The tub used a 1 1/2" drain, and the shower requires 2". But the existing tub drain to the stack can be easily replaced with 2" using the same routing. Two...
4. ### Best way to find out water hardness when on city water?

Not all municipal water suppliers report hardness. Get a test kit and you can test any water, any time: https://www.amazon.com/Hach-145300-Total-Hardness-Model/dp/B008FM7WLU/ref=asc_df_B008FM7WLU/

I wasn't sure if 10" was the o.d. or i.d. I infer from your math that's it's the i.d., so I have met my learning requirement for today :).

So, you're saying in general you only fill to 2/3 of the net capacity?
8. ### Water softener media expands and overflows tank after head removal

Like I said, I don't know what the problem was, but the 1.5 cu ft carton definitely held more resin that I felt fit. Dittohead's chart shows 1.35 cu ft when allocating 50% for headroom. Another chart from WC&P Magazine shows 1.3cu ft:

I had a similar tank, and 1.5 cu ft was too much to leave the recommended headroom in the tank. Maybe the box was mislabeled, don't know what the problem was.
10. ### Water softener drain issues

Yeah, I'm with Reach4; it isn't your drain line. Don't know anything about the SoftPro, but most valves I'm familiar with use source water pressure to siphon brine from the brine tank. If the source flow deteriorates, the siphon fails. After doing its siphon thing, the source water goes to...
11. ### Water softener drain issues

When you tested it, did you disconnect the drain line before or after the check valve?
12. ### Chemical Injection Tee

What does your injector require? You can go with CPVC down to FPT in 1/2" or 3/4" with SS reinforcing collar, and from there use brass reducing bushings to (e.g.) 1/8". And if you're worried about future replacement, blow the extra \$4 and buy 2 now.

14. ### Well Water Results - Need Recommendations Please

Only issue I see is pH, maybe. One f my naturalist doctor friends likes to see neutral or slightly alkaline, but also recommends Evian. Interesting article about Evian in Forbes...

I'm finding the same advice applies for furnace filters...
Hey, wait a minute.
