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
