"Plumber charged a lot to hack up my house to fix a leaking pipe behind the dishwasher. He didn't hook up the dishwasher drain line correctly and it leaked. Had to fix myself. They used a scrap pipe instead of the proper $2 part. They wanted to charge me a service fee to come out and fix their problem. I would give zero stars if I could. Over $2200 for bad work. Avoid these guys!"

With a name like Dallas Plumbing Company, you may not think of us as air conditioning and heating experts, too. Fact is, in addition to our award-winning plumbing service since 1903, we are also one of the top licensed commercial and residential Heating, Ventilation and Air Conditioning Contractors in the Dallas - Fort Worth area. That simply means we know plumbing, air conditioning and heating and we do it right. Our goal is to earn your trust and keep you as a valued customer from now on. And, we back it up with our 100% Satisfaction Guarantee. Look to us for all your plumbing needs, and let us provide a free estimate on any new heating and cooling equipment you are planning to purchase. If your system needs cleaning or repairing, we can service all makes and models.

"We needed a shower head swapped from one bathroom to another and scheduled the work for the next day. We got call at 9:23am where they said we were next on the list. Then we got a call at 11:40am to say the plumber was on his way. At 12:25 we got a call from the plumber saying he'd be there in about 30 minutes. He spent about 15 minutes here to swap out the shower head. They charged a flat rate which we were not informed about until the plumber got here - it was $242. If we refused the work they would charge $131 for the trip charge. Again this was not communicated at the appointment scheduling. The plumber said that the company had been sold about 1 year ago and this is what it was now. We had used Dallas Plumbing for over 30 years; not anymore. The customer service is gone and they don't have any concept of small job pricing."

Septic Tanks questions, answered by experts

If you notice that your well pump runs continuously, it’s important to take action quickly to avoid further damage. A few common issues may be to blame for a continuously running well pump, such as mechanical damage, a faulty pressure control switch, low water level, prime loss, and leaking pipes and fixtures.

The main difference between a mound septic system and a conventional one is that the drain field in a mound system is built up into a mound composed of sand and gravel to increase the filtration time the wastewater sees before it is returned to the aquifer. There’s also a significant cost difference, with mound systems typically costing far more than standard septic systems.

DIY is not recommended due to safety and technical requirements. Hire professionals for accurate diagnosis and repair.

Frozen well pipes make themselves known quickly, as your faucets slow down to a trickle or shut down completely. If you notice a serious reduction in flow in the winter from toilets, showers, kitchen faucets, and other plumbing fixtures, a frozen pipe or two is to blame. Another tell-tale sign is frost or ice on exposed pipes outside. 

Septic systems typically require servicing every 3-5 years, but frequency varies according to household size and tank capacity.
