"3/14/2020 My elderly parents live with me - both have health issues. We had an emergency where water was spewing from a pump outside. Even though it was Sunday, Farrell Plumbing had someone come over and were quick to fix the problem. I was really appreciative of their response, professionalism and their fair price. I was very glad they could come and help us out. I don't know what I would have done if we didn't have running water with everything going on at the moment."

French Drains FAQs, answered by experts

You’ll likely pay between $300 and $450 to unclog your toilet with Roto-Rooter. However, the price could change depending on if the clog has caused a lot of damage, which your plumbing pro will want to inspect during your service appointment. Keep in mind that you won’t get a quote from Roto-Rooter over the phone. They have to send a pro out for an in-person cost estimate. You can also attempt to snake your own clog for a lot less, and simple drain snakes cost no more than $50.

Common drain issues include slow-running drains, whether in a sink or shower, clogged drains, a bad smell, and water backing up into a sink, shower, or bathtub. Causes range from hair, grease, roots, or toilet paper clogging the drainpipes to flooding outside the home, which prevents sewer lines from draining properly.

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. 

That pungent rotten egg smell coming from your drain is likely the buildup of biofilm—hair, skin, and soap scum that turns into a black sticky mess. In this case, pouring down near-boiling water, baking soda, and white vinegar will remove the smell. Keep in mind that a rotten egg smell is occasionally a sign of larger sewage line clogs and other related issues.

The P-trap (or S-trap in older homes) under your shower is designed to prevent sewer gas from coming back up, so you shouldn’t normally experience foul odors coming from your shower drain. If you do, the vent stack that introduces air into your plumbing system may be clogged, or you may have a more severe sewer main blockage. In either case, hire a plumber to fix the issue for you.
