I have used Instant Plumbing for about five years, when we needed two water tanks replaced I did not hesitate to call them. I had to call them after installation as one tank started leaking again, Gary came out and could not replace the part for another week as he was going on vacation. I scheduled another guy from Instant plumbing and he came five days later, I noticed the smell of gas the day after installation, still after three days smell of gas when the guy came to replace the part I mentioned to him the smell of gas, said he checked and all was good, Couple more days go by and I called the Gas CO. they came in and tested sure enough there was a gas leak. Left an email on companies email and never heard back. Now I am dealing with another leak from the tanks that were installed a month ago Will not be using again.
