The link works fine. I clicked it again directly from the post I provided just to make sure. It is a 17.3 MB HansGrohe Technical Manual in .pdf format that contains the specific valve that genogardner installed with diagrams for install depending on how one wants it to operate.
TheMaster:"I cant find any that says NOT to install a loop and specifically says it will work without a loop....Can You?"
Pages 19-20 answers your questions.
Ok I got the link to work and I already read that. Its not a piping diagram is a layout/function diagram. Sure depending on what the flow rates of the bodysprays are it would not be noticable with lower flow rates......MAYBE. It depends on the location of the sprays in relation to each other. I even said that already that I believed it worked when just the body sprays are on.
Balanced loops work every time.....thats why geno attempted to do one...then in the middle of it he decided to do a hybrid parallel/blanced loop design that didn't serve a purpose or match the "layout" by hansgrohe.
So what kinda piping did he do? Art? Hybrid top secret engineer fluid dynamics?
What diagram did he follow? Find that diagram for me.
And another thing. Where's the nobility in admitting your mistakes
if you're not willing to correct them?
There was no mistake made....the pipe has a ding in it. BFD. With the flow rates of a shower valve its not an issue.....again fluid dynamics comes up I bet a propress connection does more than that to copper...what do you think?
Wait, oh crap now someone is gonna' want to tell me all the ways I don't know anything at all about the wax in some valves.
Ya'll remember Devo?
You two guys need a tent to throw over your circus instead of a plumbing license.
I'll stand by a balanced loop is the proper way to install bodysprays and what genogardner posted as an example of his pipe bending turned out to be a chinese puzzel that he punked himself with...while he was taking a STAB at my work.
Oh, so you installed that piece of dinged copper on purpose?
As for pro press...never used it, but I have seen plenty of leaks
from dinged copper pipe. Admittedly it takes time, but it can
and does happen. Why take that chance?
Sorry but the flow rates are not enough to make a difference for a shower valve. I didn't install it on purpose but I would have installed it anyway because I know it will not matter with the flow froma shower valve. Theres no chance being taken. Do your homework on the subject,I cant teach you what I've learned from years of study and practical experience on a forum.
