Plumbing questions, answered by experts

If you know the job is going to be extensive (and you don’t like surprises), hiring a Roto-Rooter specialist may make sense for you. You’ll know how much you’re going to pay right away.

That said, hiring the best plumber isn’t solely about price. If you've worked with a plumber you trust before or have a list of plumbing services you need tackled at your home, working with a plumber might be a better choice for you.

Dripping or leaking water from the handle or dripping from the showerhead (when its off) are signs your shower valve needs to be replaced. Other signs include low water pressure and inconsistent water pressure and temperature (that isn’t caused by other factors like someone else using another fixture at the same time). Difficulty turning the valve and water not turning on at all are advanced signs that the valve is wearing out.

Toilet paper is the only material that you should flush down toilets. Other items like wipes, paper towels, feminine hygiene products, dental floss, and medications should be disposed of in the trash. Flushing these items can lead to plumbing issues and damage to sewage systems. Grease and cooking oils should also be avoided as they can solidify in pipes, causing blockages. Proper disposal helps prevent clogs and ensures the efficient operation of wastewater treatment systems while protecting the environment.

If you notice smells or clogs, you’ll know something’s wrong with your shower drain P-trap or the plumbing. Most of the time, smells and clogs are due to a clogged P-trap. However, in some instances, you may smell sewage. If this happens, open your windows and contact a plumber to help. They can do a plumbing inspection and let you know if anything needs to be repaired or replaced. Common culprits are a dry drain, cracks in the plumbing, or a clogged vent.

If you try a drain snake and various DIY methods for unclogging drains to no avail, bring in a professional plumber to assess the situation. Also, if multiple drains in your home are backing up or you smell sewage, a visit from a plumber is best. You can expect your drain cleaning costs to fall around $250, and this can include an assessment of what’s caught in your plumbing and if there’s a larger, underlying problem. You should also consider calling a pro if you need to snake a toilet, as DIYing this could lead to a cracked fixture.
