"Andrew was great on time and personable. He knew what he was doing and even showed me the issues. He fixed what he was able to and advised me on what I need to do next since the next issue was not the plumbing. When I was urgently looking for someone to come fix the leak I had, everyone else was unable to make it the day of. Andrew made it in an hour from speaking with him. I would recommend his services to anyone needing a plumber."

"They cut out the old dry wall, removed any and all mold, then replaced the dry wall, placed a tub and shower unit, they had their plumber come in and adjust our piping and install our new shower head and tub faucet all within 6-7 hrs. The installers were very nice, respectful, polite young men-- I would 10/10 recommend this company!!"

Plumbing questions, answered by experts

The amount of clean water your cistern can supply depends on its size and the local rainfall patterns. Cisterns range from a few hundred to several thousand gallons in capacity. 

To estimate the potential supply, consider the average annual rainfall in your area and the catchment area of your roof. For instance, a 1,000-square-foot roof can collect around 600 gallons of water from just one inch of rainfall. 

Multiply this by the average annual rainfall to get a rough idea. However, factors like evaporation and system efficiency will also play a role.

If you notice water dripping from your bathroom fan, you likely have an accumulation of condensation. The fan pulls warm, wet air from your bathroom and into the attic. However, if the water accumulates as condensation over time, it can begin to drip back out of your bathroom fan. It’s important to take action quickly to prevent mold growth and water damage.

National emergency plumbers usually have greater availability to address emergencies because they have more professionals at their disposal, but local plumbers may be located closer to your home and can arrive faster. We recommend contacting one or two local plumbers first to see how quickly they can arrive. Move ahead with the service if it’s within a reasonable time frame. If not, contact a national company to see if they can get out more quickly. National companies sometimes outsource work to third parties, which can often mean faster response times.

Depending on the location of the water leak, it could go undetected for weeks, months, or even years in some extreme cases. Most homeowners who have plumbing leaks have slow drips, so you might not see signs of damage until they become severe problems. It’s a good idea to have a plumbing inspection done annually and to take steps yourself to check for leaks, including inspecting your floor, walls, and ceilings for signs of water damage, monitoring your utility bills, and looking for water around appliances and fixtures.

Showers frequently experience leaks, most commonly originating from either the faucet or a malfunctioning shower drain. Detecting a leaky faucet is straightforward—listen for the constant sound of dripping water, even after you believe you've fully closed the faucet. In the case of a shower drain issue, it is often characterized by water seeping from the base, usually caused by a deteriorated seal between the shower wall and the shower tray.
