"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."

"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."

French Drains FAQs, answered by experts

It’ll take 20 to 30 minutes to unclog a sewer line using a drain snake or drain cleaner. If you hire a professional, you should expect them to be on-site for three hours or less. In addition to clearing the clog, they’ll do other routine inspections, which adds to the overall time (and cost) required.

To clean gunk out of a sink drain, pour in a half cup of baking soda, then 1 cup of white vinegar. The two will react chemically; let them fizz for 15 minutes, then rinse with boiling water. Repeat these steps if necessary for particularly dirty sink drains, and consider a drain snake if there are clogs.

Drain clearing removes debris and clogs from drain pipes enough to allow water to drain properly. On the other hand, drain cleaning removes all of the material from the pipe so that water flows unrestricted, which is a longer-term solution. Your plumbing pro will be able to recommend the right service depending on the clog size, frequency of issues, and surrounding pipework.

No, it is not advisable to spray pesticides down the drain in your home. Most drinking water and wastewater treatment systems are not properly equipped to remove pesticides. Should pesticides infiltrate waterways, they can cause harm to plants, fish, or other living things. In most areas, pouring pesticides down the drain is illegal due to the potential harm it causes. 

Inspect regularly for clogs, clean drain lines, and ensure grading directs water away from the foundation.
