How Does An Earthquake Valve Work?

For homeowners throughout Califonia and other earthquake-prone areas, regulations are in place to keep your home safe. With a seismic valve – sometimes referred to as an earthquake valve – your gas supply is automatically cut off during seismic activity or when the line is damaged. These devices are triggered by shaking, loosening a metal ball from above the main line that dislodges and blocks the gas line. Reach out to our team to schedule your seismic valve reset.

What Happens When An Ejector Pump Fails?

If you live in a home with a bathroom or appliance that sits below your main sewer line – like in a basement – you likely have an ejector pump. This device forces wastewater up to the main sewer line and out of your home. If your ejector pump is not working, greywater or wastewater can back up into your appliances, block your plumbing or cause flooding. Reach out to our team for dependable ejector pump repair!

Why Is My Disposal Humming But Not Running?

A garbage disposal can make kitchen cleanup easier, helping you wash away plate scrapings with ease. But a malfunctioning disposal can be a real headache. If your unit is humming but not working, the problem isn’t electrical – it’s likely a jammed element or a broken motor. With garbage disposal repair from our team, we’ll get your kitchen routine back to normal!

How Do Pipes Run In The Bathroom?

For most bathrooms, you’ll need to have five water lines installed – a hot and cold line for the sink, hot and cold for the tub/shower and a cold water line for the toilet. Your home’s water lines need to connect from the main water line, then branch off and connect to the water heater before hooking up to fixtures in the bathroom. Gotelli is your trusted bathroom plumbing company for all your home’s pipes!
