BWE 10 Inch Square Bathroom Luxury Rain

I purchased this combination a year ago and it professionally installed. Love the look of the product. Looks great in my shower. However, after having it installed for about 8 months, my shower would randomly start leaking from the shower head and continues to do it. I sent a video to the plumber who installed the shower and he came out and looked at and tested water pressure around the house and determined that the pressure valve control unit was faulty and that we would need to be replaced. With having a year warranty on the product I emailed the manufacturer (IN CHINA) and told them the issue and requested that I have a new valve unit sent. My response back was. Prove it and the only way that they would replace the unit was if I took it apart, (Compromise the seals, and everything else.) find the faulty part (Like I would no exactly what I am looking for) and prove that the unit was faulty with a photo or video. Then be without a shower until they can send my a new unit if they determined it was faulty enough. Now I am having to spend another couple hundred to replace and fix there faulty unit with a completely different manufacturer who produces generic valve units. Hopefully that doesn't create a whole other set of problems. Once I get it replaced and can take it apart, I will send a pic and ask for a refund for the part. But I am sure I will never see that as well. Stay tuned.....
