Customer Questions & Answers

purchased a 19822 single function thermostatic valve with 13603 tub spout with diverter. Whenever I transfer water to come from shower by pushing the diverter button on the spout the tub spout leaks water into wall. A replacement spout provided by company yielded the same result. any thoughts as to what could be causing this??
Asked by: mike
The nipple for the spout may not be roughed out far enough. The o'ring on the adapter may need to be greased with a plumbers grease or white lithium grease.

Authentic 2-Handle GrohFlex Universal Rough-In Box Single Function Thermostatic Kit in Chrome is rated 4.0 out of 5 by 2.
Rated 4 out of 5 by from You get what you pay for and you still have to do your homework& research Latest project is now wife's basement bathroom renovation. Wife and I settled for this Grohe thermostatic tub/shower faucet. Me I'm a die hard American Standard disciple however we decided to go Grohe after countless hours researching via the web. Talk about quality and engineering ....quality brass castings for both valving and trim along with really nice chroming. We choose Grohe especially the Grohflex technology because if we ever want to do a mild bathroom refresh all we need to do is just swap out all the exterior Grohe trim and possibly the control module, which is the behind the wall Grohe valve. Talk about easy maintainability.... easily accessible water service stops for both hot and cold supply lines(no more shutting down water for house to do repairs and upgrades) , a thermostatically controlled to pressure balanced change out is removing 4 stainless screw valve body screws for change out. Impressive is the showerhead gooseneck nipple which reeks German design and quality. How many times have homeowners had to replace a leaking/rotting showerhead gooseneck nipple simply because they were all constructed out of thin badly chromed metal? The Grohe showerhead nipple uses quality thick chromed pipes similar to the old 1950's threaded brass piping. Only caveat is the fact you must purchase and pre-install the Grohe 35026 rough out behind the wall otherwise your project will come to a screeching halt. Other caveats to consider prior to purchase is do you want thermostatic controlled or pressure balanced water from the shower, do you want a diverter tub spout or have it contained in the valving?

Rated 4 out of 5 by from Grohe is the best I had used Grohtherm in the past, but decided to try a different, cheaper thermostatic valve for my last shower build... was disappointed. Disappointed enough after 3 years to rip out tile to install a Grohe thermostatic valve. Grohe has a smoother operation, with a better feel to the volume control valve. The other brand (Danze) would also 'whistle' at lower flow settings... the whistle would reverberate through the pipes and could be heard throughout the house.
