a hammering case

trying to diagnosis a water hammer which i havent yet had the opportunity to hear.

client initially stated that the system has a crash noise when turned on, thinking odd- i asked if they were sure if the cash happened when system is turned ON or OFF.
Client replies that they're not sure, it just happens at in the early morning hours

i did a mainline repair on what happened to be a long stretch of higher-than-the-rest elevated pipe, could it be trapped air?



on a possibly unrelated note: dv-100, in your opinion, is it fast or slow-closing?
and
In relation to the dv-100 will a toro 260 close more slowly under the same variables?

the classic Toro valves were always the slowest to close when using the manual bleed

Rhett, is this on city water or a well?

How long is the run?

If this is a main and not a laterial then the possability of trapped air is nil. A small portion of air introduced via the repair would likely have been purged from the line once the system ran for a while.

Speaking of hammer, I want to reduce the hammer from my toilet valve. Anyone have any bright ideas I haven't already thought of?

just pee outside.... less water use from not having to flush anymore.

I'm assuming you've thought of in-line hammer arrestors?

A traditional plumbed solution is not an option. The only thing I have thought of other than throttling the stop valve down, which is undesirable, would be to use something like Watts Floodsafe supply hose in the hope that it might reduce upstream hammer.

What's the water pressure?

Pressure is irrelevant in this equation, but if you must know, it is likely in the upper 40's without putting a gauge on it.

Not entirely irrelevant, since you might have room for small PRVs at each toilet supply valve, in order to run them at the lowest possible pressure.
