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.

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.

Vinegar is better for an AC drain line because it’s less corrosive and won’t damage the pipes. It’s also a safer and easier product to use. Bleach should not be used on your AC drain line because it can corrode your pipes and harm the evaporator coil in your air conditioner.

Start by pouring hot—but not boiling—water down the drain. The heat of the water may be enough to break down the clog. You can also try ½ cup of dish soap or 1 cup each of white vinegar and baking soda. If you choose a chemical unclogging product, ensure it’s appropriate for toilets to avoid damage.
