Greetings All,
I have a new 2nd floor shower using Grohe components. The first time using
it, I realized there is no cold water flowing through the mixing valve. I
can't modulate the water temp, only hot comes out. Providing there is cold
water flow to the mixing valve, what could cause the water to not be coming
out. The plumbers who did the install weren't too smart (I had to show them
how to pipe the body sprays) and I'm wondering if they were too lazy to
remove the insides of the valve prior to sweating the joints. If that's the
case, can I replace the interior? Luckily I have a spare in case 2 valves
were needed for sufficient water flow from all of the sprays, heads,
etc..... Also, is it necessary to caulk the corners (floor and wall) in a
tiled shower? I had a proper mud bed made, and he also used the brushed on
red colored waterproofing coating. I realize that grout isn't truly
watertight, so I wonder if caulk is necessary. Thanks to anyone who can
help, Mark

Single handle? Is it a case of the pipes being reversed? Will the cold come
on when fully opened?

With the water shut off at the main pull the valve and put a pail
infront of the unit turn water on have you got water coming from both
jets or ports where the valve goe's if so it is either the balancing
spool or the valve . Did you remove valve when you soldered in the
unit or did you put the valve in upside down possible ,have seen it
done .

Actually, I discovered an error while assembling the valve body handle. I
now have cold water flowing. But still wondering about the caulk.....
