"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."

"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!"

"Had a problem with a toilet flange and installing an Swedish toilet. Swedish toilets are going to be the next big thing. But the supply line feed is on the other side of the toilet and the supporting flange can't be from the 1920's. Dynamite plumbing got it done the same day. Literally perfect."

"They called us quickly and got a plumber out within a few days. Super thorough - tested all pipes and water sources to diagnose the problem. They were able to perform maintenance on most bathrooms the same day and improve the water temperature in our showers. Gave helpful, non-biased advice on potential further plumbing improvements. We will likely call this company again for any and all future plumbing needs."

"After dealing with drainage backups every month, I called PPS Plumbing and they did a camera inspection. It turns out I had roots in my sewer main line. They replaced the sewer section that had tree roots and removed a large amount of roots in the drain. They were fast, clean and very professional, and were able to complete the job in one day. Everything was explained to me and shown to me on their cameras. I would recommend PPS Plumbing to anyone in Azusa looking for a plumber."

Toilets FAQs, answered by experts

To keep your toilet in good working order, replace the toilet fill valve every five years. Toilets get quite a workout, so while toilet maintenance may not be on top of your to-do list, it’s essential to keep up with it to ensure your toilet is in good working order and ready when needed.

While gasket-sealed PVC flanges are the type most commonly found in homes, flanges come in a range of different materials, including copper, brass, stainless steel, cast iron, and aluminum, that pros sometimes secure with glue. If this is the case in your bathroom, the replacement is a job better left to the pros.

Toilet handles can get stuck for a couple of reasons, but it’s commonly an issue with the chain. Remove the lid and check the chain’s connection, running from the flapper to the handle arm. Sometimes the chain gets snagged on or against another part of the tank. 

The chain might not have the right tension. For example, a chain that’s too short can make the handle feel stuck. Check that there’s some slack in the chain. Old, worn-out flappers can get stuck, too. In this case, you’ll need to see which size toilet flapper you need.

Toilets typically connect to your main vent stack, a vertical pipe that runs through all finished levels of your home and exits through the roof. It’s located behind the walls, but if you have an unfinished basement or a utility closet, you may find a portion of it running the vertical length of the space. Some basement toilets use an air admittance valve instead, which is a small vent located in the wall directly behind the toilet that extends upward a few feet from the drain.

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.
