"The plumber spent a lot of time just trying to figure out the source of the hidden leak. He had a lot of patience. The quality of work was good as was the price. I would definitely hire them again."

"After discovering a leak (probably in the slab) of hot water, we just decided to replace the entire plumbing piping in our 30 years old 2 story house with 3 bathrooms. The copper pipes were replaced by durable flexible plastic pipes and the project also included replacing the water heater. The crew- Manny, Mitch and Josh promised to finish the project in 3 days- and they sure did it. The GREAT TEAM, efficient and professional, worked non stop and communicated with me before taking each next step. They reconnected about 20 points (such as washing machine, dishwasher, new water heater, multiple faucets and 3 toilets) The price is a little steep but the quality of the job looks very good."

"Jose from JRC Plumbing is wonderful to work with. Not only is he an expert in his craft, he’s professional, friendly, and provides great communication. The tube spout broke off in our bathroom. He was able to identify the problem, provide a clear plan of action, and give very reasonable pricing. Our tube spout was quickly fixed, and he patched the wall that needed to be cut into to reattach the pipe, leaving our home better than it was. I will definitely be reaching out to Jose at JRC Plumbing again."

"Good efficient work, showed up on time, clean, courteous workers. They gave me one choice for a replacement toilet to install the next day, so in the meantime I looked up the brand and model and found it was one of the cheaper toilets on the market. I called next morning and they offered me a better one at the same price. I should have done the same with the water heater they replaced. After it was completed I found pretty poor reviews on it. SoCal does give a 3 year warranty on labor, and manufacturer 6 years, so hopefully it will last longer than thatâ ¦ Just beware- probably with any plumbing company- Find out first what the reviews are on the plumbing fixture they're giving you before you sign off on it. As long as you do that this seems to be a reliable plumbing company to use."

"Jonathan was a great hire. He came and worked with my schedule and came on a quick short notice. He came for a clogged toilet and swapped my garbage disposal. The next day we clogged the toilet again and he came back within an hour to fix it again for no charge. Pricing is very reasonable and is much lower than other plumbers. I wouldn’t hesitate to hire him again. I plan to have my pipes looked at with a camera because I can’t have this keep happening."

Now that my sewage line is in excellent shape, Im really pleased with Danshops assistance. For any plumbing needs, especially large repairs like this one, I highly recommend Danshop."

"Very grateful for Fed! My Momâ s house had an issue with water not draining properly. Called Fed for a quote; he showed up the next morning and got to work on the issue right away. He was working by himself for awhile since it was Sunday, and had to dig through tons of rocks and roots since the land in our area are filled with stones. There were roots in the sewer line as well as buildup in the pipes; the pipes were so clogged that there was barely what seemed to be 1/8th or so of the pipe where the outgoing water/waste could flow through. He replaced parts of the line with pipes which roots would not be able to penetrate through, which gave us peace of mind as there are a lot of trees in our area. Fed and his team also added a sewer access and he replaced the filters in the toilet tanks as well. Thank you so much for helping us resolve this huge plumbing issue! Fed was honest, reliable, and friendly. Would highly recommend!"

Toilets FAQs, answered by experts

The toilet should rest 10, 12, or 14 inches from the back wall. As for other clearances, 15 inches is the minimum distance from the flange to any side wall or nearby fixture, including the shower, tub, and sink. Modern codes also require at least 24 inches of clear space in front of the toilet.

Yes, $5,000 is a healthy budget for a DIY bathroom renovation. It can go a long way in making the space more accessible and stylishly spa-like. Providing you stick to modest materials and don’t make any major plumbing or structural changes, you can upgrade fixtures, retile, and add some stylish bathroom accessories and savvy storage solutions to maximize the space.

Yes, you should caulk a toilet to the floor for several reasons. Bathrooms are constantly wet—and if water splashes out of your shower and collects on your floor, you don’t want it seeping underneath your toilet, where it could potentially cause damage. Plus, caulk adds stability and helps prevent your toilet from wobbling.

The first step to clearing the air in a line is to locate the cause. This is usually a blockage in either the drain or the venting system. Once you clear the issue, flush the system by actually flushing the toilets repeatedly. This should allow the trapped air to escape, thus clearing the lines. Don’t be surprised if there is increased bubbling as the air makes its way through the system. 

Yes, and no. Your shower, toilet, and sink all connect to the same main drain, but the secondary drains going from each fixture to the main drain are usually separate. This isn’t always the case—especially in older homes—but since toilets contain black water and showers, tubs, and sinks have grey water, toilets are more regulated and come at a greater risk of contamination. It’s best to keep these drains separate using individual waste collection for this reason.
