Epilogue:
I contacted the Toto guy again and he told me to go back to B&Q, refund the drain and buy another one. I didn't trust him so I called B&Q and asked if I could refund. The salesperson said sure. I then asked if they had other drains. Yes again. I then asked if they had drains that I could actually take with me. No. So I would have to order yet another drain and wait 40 days in order to be in the same situation again? Yes. I contact the Toto guy who I have no faith in now and he tells me to go to another place like Deyisheng to buy the drain (like a Toto store). Will they have it? Possibly.
My wife overheard this continual rubbish and eventually got involved. She told the Toto guy that he was going to send us another drain by the end of that day or she would complain to the complaints line, get in contact with his manager, and then contact the news to do a story on how shoddy the business practices had been to this point. She then called B&Q, told them they had to send us the refund by this day or should we called the complaint line. The sales person said "Go ahead. They don't care either. No one cares (rough translation)." So she called the complaints line and complained. A few hours later, she not only got the salesperson to send another drain, she got him to buy the drain and refund us the difference along with a written note guaranteeing that he would fix the drain if it broke.
The bottom line is that you need to threaten a person's livelihood here or else they will drag their feet. I still reiterate to stay away from B&Q and Toto, but at least the complaint line actually had some effect. I too have forwarded my complaints to the B&Q in the UK, but no response as of yet.
@atomic: I've been working with one person who works with many of the cafes on Wen Lin Jie. He's quite reliable and I really trust him based on the work he has done. PM me if anyone needs a foreman/installation expert.
@laotou: I agree with you. I should have just refunded everything immediately and not dealt with all the hassle. However, you sometimes just want to get things done and I wasn't sure if it would be a even bigger hassle to stop and start again. I thought of taobao before, but on my own, it seemed easier to do things in person. For future jobs, it definitely is something I want to do.
@Dazzer: We went with the most expensive paint at B&Q (Master's?) and it was great. After about 4 days, there was no smell or fumes.
@Bucko: Wow! I just don't have the time/energy/experience/knowledge to pull off what you are doing.
@Anonymous Coward: I've moved a few times in China, but I don't have a specific moving company to offer. However, be careful of two things - 1. If the company is charging by weight, do not trust their scales. Weigh everything before and let them know. We used two moving companies in Shanghai that rig the scales so that they increase in weight when you put your boxes to weigh, but seem quite normal if you step on the scales. We caught the scam and the moving people said it was standard practice to cheat. 2. Be very organized with what is in every box and how many boxes you have. A friend of mine lost a box of valuable items, but didn't notice until he had signed off on the moving receipt. Keep an inventory of every box and check it before signing off.
On a separate note, I have just had a water pressure pump installed. It's outside of the wall, right after the water meter, and it cost about 400rmb. It needs to be plugged in and you need to turn it on/leave it on when you need the pressure. Seems to work pretty well, but I don't have the specs on it. Can send more details in the future if need be.
Thanks for all the feedback and advice.
