"I just had Blue Bear Plumbing replace my 33-year-old boiler. They were AMAZING from the second I called call in!!! Angi was super friendly and helpful and got me scheduled same day. Which was awesome because I had no heat, and more importantly no hot water!!!!! Kyle a project manager was out that afternoon to take a look at my boiler and help me decide on the perfect replacement for me, which ended up being a Bosch “combo” boiler. He was patient, knowledgeable, and made the whole process easy to understand. He even found that my boiler was way too small for my house, which is why my living room never got up to temperature!!! It even looks so cool in my basement, especially compared to that big old metal box that used to be down there, I actually love it! I already recommend Blue Bear Plumbing to my neighbor for their AC project. They made my whole experience the best from start to finish!!!!"

Gas Leak Repair questions, answered by experts

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.

Yes, it can be worth installing a gas fireplace, depending on your home heating needs. The cost to install a gas fireplace can be much lower than the cost to install a comparable wood-burning fireplace. The convenience of starting a fire with the flip of a switch and turning it off just as quickly makes a gas fireplace a big time saver over starting and maintaining a wood-fueled fire. A gas fireplace also does not require ash cleanup or frequent chimney cleaning to remove creosote and other buildup that can lead to chimney fires. Gas fireplaces burn and heat much more cleanly than wood fireplaces.

Even if you invested in the cost of a gas shut-off valve for your oven and other appliances, it’s a good idea to add a seismic shut-off valve as an extra safety measure. 

Gas shut-off valves for appliances are manual, meaning someone has to cut off the flow of gas. This leaves room for error, as you might not be home or might be too distracted to think about gas lines during an earthquake. An earthquake valve is automatic and will protect your home from gas-related disasters in the event of an earthquake.

In most cases, a flexible steel hose connects your gas line to the wall. This process is typical if you are replacing your gas stove or if the old pipe has worn down. However, always leave this job for a professional plumber. Errors can be very dangerous, so it's worth calling a professional to take a look.

Yes, you can have a gas line professionally installed to convert your traditional fireplace to natural gas; just know it’ll be an extra cost to budget for. The cost to run a gas line where you don’t already have one is about $540, though most homeowners pay between $260 and $820. Your total could be significantly higher if you don’t already have a main gas line running to your home.
