"Think again if you think that these guys only do excellent drain cleaning, they also provide top notch plumbing services as well. Rocky, our plumber at Afford A Rooter, was dispatched out the day after I called. He arrived promptly, got down to business, and kept to the estimate. We no longer have the old cast iron nightmare that required constant rubbing of the white enamel, but we have instead a modern stainless steel beauty. Rocky was friendly and despite what to me seemed like a job with some technical challenges, got it done in no time and left the area spotless."

"Gary, the master plumber who came to our home and gave us an estimate and did the repair work was personable, friendly, professional, and very thorough. He was the main reason we went with Rooter Guy. They were the most expensive of the quotes we received ( we had 4 estimates). The solutions Gary provided were the least intrusive to our plumbing disaster. The work they completed is wonderful and we feel very confident the repair will last for a very long time! The day of the repair job they communicated well and cleaned up everything perfectly. I could not be happier with the work - just wished the job was a little less pricey. We have kept Gary's card and will call again for major plumbing jobs in the future."

Plumbing FAQs, answered by experts

A back pressure valve is a control valve used on production vessels, such as separators, treaters, and free water knockouts. The valve holds pressure until a set point is reached, and then releases upstream pressure to reset. Back pressure valves are not safety mechanisms. Instead, they are regulators designed to keep the fluid, gas, or liquid mixture in a system at a certain pressure level to prevent bursts and other incidents.

Meanwhile, a backflow preventer is a safety mechanism that kicks in when the pressure has already failed and contaminated water flows in the reverse direction. Most backflow preventers consist of two one-way valves, or check valves assembled together. This design only allows water to pass through in one direction but not the other.

Yes, insulating your cold water pipes is a great way to prevent condensation. When warm, humid air meets cold pipes, condensation forms, which can drip and cause moisture issues in your home. Pipe insulation acts as a barrier between the warm air and the cold pipes, keeping condensation at bay and helping you avoid potential problems like mold or structural damage.

In the best-case scenario, the pipe size is written on the side of the pipe. You’ll often find this with different types of plastic piping like PVC, PEX, or CPVC. For other types of pipes, you’ll have to measure. You can measure the outside circumference with a soft tape measure, then divide your measurement by pi. From there, you’ll have to use a conversion chart to get the nominal pipe size (the size you’d buy in the store).

Yes, you can water plants with water softened with potassium chloride. Potassium is a vital nutrient for plants, so using this type of water is harmless and can even be enriching. It is often a better option than water softened with sodium chloride, as too much sodium can build up in the soil and make it difficult for plants to absorb the water they need. If you notice that your plants are not tolerating the treated water, try letting it sit in a watering can for one to five days to allow the chlorine to diminish.

Some of the most common plumbing repairs are certainly no small issues. The good news is that plumbers typically deal with these problems frequently and have the parts and tools ready to take care of them quickly and efficiently. These common problems include:

  • Clogged drains: $75–$250

  • Clogged toilet: $125–$300

  • Bathtub and shower: $100–$600

  • Faucet or showerhead: $200–$350

  • Sink pipe: $200–$500

  • Toilet repair: $150–$400
