"Very well. It is an old house with no straight walls. Craig worked diligently to make sure the bath walls we purchased fit and were plumb. The floor was also a challenge being uneven which Craig did very well addressing it. He used various techniques to level the floor and place the new tile. Very easy to work with and he had good solutions to the problems he faced. He always checked with us to be sure his actions met our expectations."

Plumbing FAQs, answered by experts

According to the EPA, there is no safe level of lead in the blood, and so the maximum contaminant level goal (MCLG) for lead in water is zero. Even at low levels, lead is harmful to human health. It can also remain in the body and build up over time with repeated exposure.

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.

Draining is the process of removing sediment buildup that has accumulated at the bottom of your hot water heater’s tank. Flushing is a more elaborate process that involves running fresh water through the tank to clean the inside thoroughly. You should at least drain your hot water heater once per year and flush it every other year—better yet, alternate between draining and flushing every six months.

The size of a pipe isn’t always the outside or inside diameter. Rather, it’s a nominal diameter that depends on the type of pipe. For male pipes, you’ll need to measure the outside diameter. For female pipes, you’ll need to measure the inside diameter. You’ll then need to use a nominal diameter conversion chart to get the actual pipe size you’d buy in the store.

Most toilets have a 12-inch rough-in or hole, but some have 10- or 14-inch holes, which means that not all toilets fit all setups. Knowing how to measure the rough-in is essential, so you purchase a toilet that fits the existing drain hole. It can be costly to have the rough-in moved, and most stores don’t accept toilet returns.
