Best Water Purification System Repair in Houston TX

Had a mainline drain clog after moving into home I've been renting for years. Called GAP Plumbing and they responded quickly and cleaned the main line and were very reasonable on cost. 3 days later, drain issue when ran upstairs shower that caused downstairs toilet to overflow. They came back and had to pull the toilet to clean out the clog. Very professional, friendly, and worked hard to take care of the issue!  
I will definitely use GAP Plumbing for any future plumbing needs!  
Used Les Conn years ago, but they were expensive and then a couple of years ago as landlord living in CA, they would not provide service since I was not on the property. Horrible customer service.
I rely on yelp for reviews, but don't often write them, but wanted to share my positive experience about GAP for those in need of a good plumbing service!

What a great experience!! So happy I called Champion Plumbing services with my plumbing problem. I was able to get an actual human on the phone within 2 rings, and then, able to get on the schedule for the same day to have problem looked at within 5 minutes. And if all that doesn't sound great, it gets even better. John sent me a text message letting me know he was in route over an hour and a half ahead of the scheduled time and got here one hour before the appointment. What?!? That never happens. He shows up and his very mindful of being socially distanced while taking all the precautions he could to keep my home clean while working on my problem.

Being the pro that he is it only took him 20 minutes to get everything working correctly.

Can't recommend this place enough. Also, very reasonable pricing.

Very rude, and impatient. There are a lot of plumbers in the area I would strongly recommend looking elsewhere.

BEWARE!!...if you don't respond in a timely manner..the owner becomes pushy and rude...And this is the owner!  Can't imagine what the rest of his team is like. Ive recommended interpersonal communication training for him. Or business communication 101. I would give 0 stars if I could.

Wayne the owner seems to know it all when we had him out to drain out dual gas water heaters in the attic, and his experience definitely shows.  He was very thorough, told us about the quality of the water we have, and all there is to know about these heaters, how they are set up, connected, and everything else about their operation, as well as what to do and not to do for their maintenance.  Definitely would recommend All Phase Plumbing anytime you need a plumber that's honest, experienced, and reliable.
