Best Plumbing Installation Or Replacement in Saint Louis MO

I had my hot water heater go out and Orr came out and scoped out the situation and determined the needed parts & labor.  They returned the next day at the agreed to time and proceeded to do a good job installing the new hot water heater.  The technicians were friendly and knowledgeable.  I was somewhat concerned about the age of all the connecting pipes, but it wasn't an issue, even though their technicians were able to determine that my bad heater dated back to 1986 (I'm only the second owner and I've owned the house since 1995).  Under the circumstances I was very pleased with the timely response from Orr Plumbing.  But this story is not quite finished, after cleaning up most of the water and associated damage, I determined there was still a leak and it was causing a riverlet across my basement floor.  Upon further investigation, I was able to determine that the source of the leak was the main inside shut-off valve.  I called Orr and ended up speaking with Mr. Orr.  He gave me a quote for replacing the valve.  When the technicians showed up, they determined they could rebuild the valve at a much lower price, so I had them do the work.  They even sent a technician to my house a few days later to pick up a check as the check I left them was for the original amount, which they didn't take on the day they performed the work.  A very nice piece of customer service in the eyes of this customer.  Thanks Orr Plumbing for quick and good service, they were straight shooters to do business with.  I will definitely call them again the next time I am in need of plumbing services.
