"Had gurgling from 2 bathroom sinks. Not knowing if this was a concern, I reached out to Angie's List for quotes from plumbers. The first one to respond was ValDel Plumbing. They were able to schedule me in for the next day. Our plumber, Steve, arrived and diagnosed the problem - partially clogged sinks. He corrected the problem per the quote. While working on the sinks, he noted that the drain pipes connected to the p-trap should be modified (he did this at no extra cost). After the job was completed, I had a question about my sump pump. He offered to look at it and gave some recommendations. Overall, I felt that the job was corrected to my satisfaction. The work done by Steve was both personable and professional. If I had future plumbing needs, I would strongly consider ValDel Plumbing."

"There were about 6 things and altogether it added up to about $800. Since then I haven't called him back. I would give him an "A" for the estimate. It's just that the most important item on there, he said I didn't need it, because it was a matter of turning the shower off, I mean the diverter off. That is not the case, I tested it several times and it does need something, I don't know what. Since I had gotten the tub refinished I didn't want to have water dripping in it. I can't seem to find a plumber that wants to do that particular small job. He's one of a couple that I asked and they all said, all you have to do is turn it a certain way, but that is not the case. I have sort of put it on hold. I liked them. I liked him and the assistant, Brendon Nagle and his assistant. They are very nice and I felt they could do most things. I have to call the guy that refinished the tub, because he suggested I get this part and no other plumber seems to agree; but I know it's the case. I do not want to ruin the tub. It causes rust around the drain, the water sitting. It's complicated. I would call Brendon Nagle again, but I have to research this particular project. I thought the price was fair, but it didn't seem like a bargain to me. Even though the quality is not applicable, I would give an "A" for knowing and being jolly. They were there the next day."

""Jay" from ValDel Plumbing showed up exactly on time after I arranged appointment on short notice. The quoted price I thought was high. But, we agreed on a reasonable price. Our 3rd time using Val Del. I don't even bother calling others anymore. This time I had leaking fixtures from an old Water Softner. The unit was too heavy to remove. So, Jay had 2 DelVal workers come out at 8AM the next morning. They removed the heavy salt from the unit (messy back-breaking job, and removed unit, cleaned up. I would never call another plumber."

"After dealing with roto rooter and Losch plumbing with very bad experiences. Thank God for finding Once & Done. Very professional crew, they did a great job in installing the new sump pump that we definitely needed. Jeff was very honest and nice and explained everything that had to be done in detail. Highly recommend."

"Suddenly, my basement drain was backing up! A friend tried to unclog it, but to know avail. He thought it might have something to do with the sewer line that ran to the street! Right away, I started seeing dollars signs. So, I went on Angie's list and saw the reviews for HL Bowman. Because they were so highly recommended, I went to their website. Immediately, there was a person named Tiera to chat with. I explained my situation and she asked me a few questions. She told me she would have some one call me. I asked if it would be today because there was sitting water in my basement and I was afraid to even flush a toilet! She said it would definitely be today! Within two minutes of concluding the chat, my phone rang. A very courteous person assured me that he could get someone out there today! It was about 8:30 am and he told me that he could have someone by this afternoon and they would call me before they arrived. Around noon, a young man named Clayton called and said he was on his way. When he arrived, he went to basement and checked out the situation. When he came up he said that he thought the clog was in the pipe along the wall going out to the sewer. He brought in a machine and spent approximately and hour and a half trying to open the clog. He then told me that he had called another person from the company to bring a larger machine. Then, Corey showed up with a huge machine and Clayton left to go to another job. Corey was down there for about another hour and half. The machine was much louder than the first one. I was really worried about the cost and the fact that it was taking so long to open. I pictured having to have my lawn torn up and imagining what that would entail, not to mention the cost. Suddenly, he appeared and I tried to prepare for the worst. He looked at me with a smile on his face and said, "it's open". I was so surprised, I am sure he saw the relief on my face. 'He explained that he had to go out 75 feet to the street, and the that the clog was because of tree roots which he grinded through. I knew this machine was probably more expensive to use than the smaller one. So I braced my self and I asked him what the total charge would be! When he told me, I was shocked as that even included the $70 service fee which included up to 45 minutes to diagnose the problem and give me an estimate. But, because Corey had to bring a bigger machine and stay longer than Clayton had estimated, I was sure it was going to be astronomical. Corey said he would figure it out! When he told me the price I could hardly believe my ears. It was half of what I had anticipated! I was thinking about $1,000- $1200! I can't begin to explain how relieved I was.. I would like to say both Clayton and Corey could not have been nicer. Very mannerly, friendly, and polite. When Corey left, everthing was cleaned up! No sewage anywhere. And another thing that I thought was extraordinary, was how unafraid they were of my two pittbulls. They petted them and Corey even told them to stay when they tried to follow him out the door. LOL! And they, listened! I have found my company should I need any future help. It's good to know that there is someone out there who is professional, knowledgeable, and who charges fair prices. It wasn't cheap, but I believe it could have been a lot higher. Family members also thought the price was good. It started out as a bad day, but I had a smile on my face when Corey left!"

French Drains FAQs, answered by experts

Your garbage disposal is not draining because it might have a clog due to food waste, a foreign object, grease, oil, fat, or it may have a broken motor. When water doesn't flush out of the disposal, that's a key sign that your disposal has a clog or needs repair. 

If you're dealing with a clogged sink drain, you may be able to avoid removing the drain by using a plunger to dislodge the clog. While we associate plungers with toilets, they can do the same job with your sink drain. Be gentle, though, as forceful movements can push clogs further into your plumbing system and make them more difficult to remove. Additionally, make sure you’re using a sink plunger—with a flat bottom—and not a toilet plunger—which has a smaller bottom protruding from the larger flat piece.

Regrading your yard can often fix drainage problems. You can also try aerating the lawn to encourage better drainage or install a new drainage system to prevent water from pooling in certain areas.

Anything from debris, rust, ice, and even poor installation can cause clogs in your plumbing vents. Some signs of a clog include slow drains, gurgling sounds in drains and toilets, and bad odors. The bad odors are the most concerning, as these can include methane and hydrogen sulfide. Contact a plumber to come take a look if you notice any of these signs.

A saturated leach field can result from various underlying issues, so it's best to call a professional septic company to diagnose and treat the problem. Depending on the cause of the saturation, potential fixes include pumping out a full septic tank, adding more bacteria to the tank, or regrading the soil to fix low spots. It may also be necessary to reroute rainwater and runoff away from the leach field using gutters, downspouts, and extenders. Once the primary issue is resolved, planting specific types of vegetation over the area can help absorb excess water. In more severe cases, you might need to install a larger septic tank or replace the leach field entirely.
