Hi,
You linked your data feed twice. Any chance you could correct the 2nd link so that we might be able to assist?
Google Merchant Centre is always a lot of fun. I had a client's products rejected continuously for 2 weeks recently, and then magically accepted on Tuesday.
Let me know if you can take a screenshot of the errors in your merchant centre and I'm sure we can solve this 
All the best,
Matt Davies
Hi again
Using the same IP address for two different plumbing websites would not cause a problem in terms of Google listing. The search engines don't check IP addresses and decide to downvote anyone's search results on the basis of being on the same server or being in the same industry.
As per your other question, as long as the content is unique - you should not experience any problems at all. You've mentioned that the content is totally different, so it sounds to me like you've got this nailed already.
Regards,
Matt Davies
