    90s Grohe & Hans Grohe WERE high quality in the late 1980s, but got "competitive" more plastic..In the early 90s.  I'm a Kohler guy or some of the real high end stuff like Dorn Beach and custom brass places.  Mad Dog 🐕

    The race to the bottom is about over. Its all junk. We installed a couple of Rohl rough in valves last week. No instructions, no markings to indicate depth in the wall.

    Moen is complete garbage.

    Kohler isnt much better.

    Symmons shower valves. So far so good. Have repaired and installed thousands. They are the inventors of anti-scald technology that all other companies use now. Not exaggerating. Use them with confidence.

    I have installed Grohe Rapido and haven't had any problems. There are a bunch of videos on You Tube to help you do it correctly.
    Plastics have become an important method of keeping prices low and competitive. You can thank your local inflation creator for the trending 'make it cheaper' and give it a one year warranty business model. Expected replacement???--One Year and a Day!

    I’m currently installing a Grohe Smart Control. It has this eccentric adapter that I would like to talk about when I have more time I will check back to see if you’re all still here and interested. There doesn’t seem to be much out there about this and after 20 years in the business I’ve never seen this nonsense.

    Just a homeowner here, but pretty experienced do it yourselfer/mechanic. Last spring I installed the Grohe Rapido smart box and a two nob shower control (diverter/volume top knob; temperature bottom knob). It was kind of challenging but after going through it, after almost a year's use it works pretty well. I found the "pictures" instructions were tough to follow, but if you persist they are pretty accurate. The installation videos are really quite good. I did have some trouble getting the threaded plumbing to Rapido box to seal without leaking using just teflon tape, in the end I had to use both tape and brush on thread sealant. I did get rapid telephone help using he call in line and the person on the other end was quite knowledgeable. Overall I'm happy so far with the installation, but I remember thinking that if I was a plumber and had to do this for the first time (cause homeowner picked the fixtures) it would take a lot of time to learn and a challenge to bill for all the learning time; and thinking that it would be helpful to hire a plumber who had specifically installed some of these prior to me, so I didn't bear the cost of education.

    Gsmith, thanks for your helpful homeowner's perspective. Indeed, it is not uncommon for clients to hire us and surprise us with an unfamiliar brand of hardware (thanks, internet). I have rejected some "Asia/Euro-devices" that I couldn't/wouldn't connect to the house. If I am able to give input before the brand decision is made I tell them to stick with major, recognized U.S. brands Kohler, Moen, Am. Stand., Symmons, etc. That alone gives them hundreds of thousands of options.

    this is my gripe with grohe on this one. The eccentric adapter with “stippled” threads. I don’t know how else to describe them. That’s how they come though. For what purpose I can’t imagine. Then they send you about 2 feet of the thread sealing cord (loctite 55) that you “need to use” the threads aren’t tapered like a standard npt. Why is this engineered into it? I look very closely at my work, maybe this doesn’t trip up too many people. In my area at least most guys wouldn’t even notice the thread sealing cord and just use regular tape/dope. The house I’m installing this in is the nicest I’ve ever worked in. It’s directly over a magnificent great room filled with suits of armor and artwork(straight out of a movie type thing) I can’t afford a leak.

    Also- I roughed my drop ears in the wall perfectly level and at the specified center line dimension. I really struggled with the eccentric adapters to find a position where they would be level with one another and be the correct distance apart. I’ve installed many many wall mounted faucets or mop sink faucets or whatever you call them in your area and never had this issue. Just want to get this info out on the internet and possible help someone else

    Sending you lots of sympathy @AndythePlumber. I don't know what those stippled threads are for. Never seen them before. That photo doesn't make me a fan of Grohe or …his brother "Hans" (That is some nice carpeting those fittings are laying on!). I will also mention that I am not a big fan of Rohl.

    I had trouble getting the weird threads to seal and customer service told me that threads like this are common in Europe as they use a fabric like, hemp sealing tape.

    thanks for the sympathy. They put a man on the moon, I will get the done. Clear carpet tape is difficult to see in the picture, it’s there though😂. Graham I believe you are correct, but why? It’s 3” from a perfectly good npt. Anyone have experience with X-pando? I’d like to finish this installation today and I don’t have any more of the loctite 55. Amazon is about a week out for it and no one in town stocks it

    That is a hemp thread. The knurling is to better grab and hold the hemp.

    Loctite 55 thread is a little easier to use. Some pipe dope helps, but is not used by the true hemp pros :)

    Yep. Had a 60 year old one in my mom's house. Still working. Excellent valve.

    the problem i had with the symmons tub and shower valve is that it is designed to allow some water to still leak out of the tub spout when being used.hard to convince a homeowner to pay you when the valve dosent work. just my opinion.

    Never bothered me, but if someone is picky, add a diverter.

    This isn't a problem exclusive to Symmons. However. Symmons shower valves are extremely reliable and repair better than any other I have seen. The spout drip on a Symmons is a repair that takes well with a high success rate. Other shower valves…not as much.

    According to Hahnsgrohe tech service and several successful installs you don't need the hemp tape or Loctite 55. A few extra wraps with tape, some pipe dope and it will be leak free.

    the valve is desighed to let some water drip from the tub spout while the shower is running. at least that is what i was told by tech support
