"Jason was professional, efficient and amiable. I had an inoperable bathroom that befuddled a contractor and another professional plumber. In one afternoon of troubleshooting the problem Jason located and solved it and did so for an honest and reasonable price. I was very impressed and would definitely recommend Donathan Plumbing Company !"

"We had a terible drain clog and had backups coming into our toilet and shower. We called Diamond House Plumbing and they sent Jeff out right away. He was able to clear the blockage, pulling out many roots and blasting our lines clear with a very impresive water hydro-jet system. I would highly recomend Diamond House Plumbing to my friends and family and anyone in need of professinal plumbing services. Thank you!"

We highly recommend Dave Hurtado for all your plumbing needs!"

Plumbing FAQs, answered by experts

If your toilet is still leaking after replacing the toilet flapper, then you may not have installed the toilet flapper correctly. Double-check that you have placed the flapper over the overflow tube correctly, and check the flapper chain is at the right length. If your toilet is still leaking, then you may have another problem on hand. For example, you may need to replace the toilet wax ring or replace the toilet fill valve if your toilet is wobbly and leaking from around the base.

A water closet is a room within a bathroom where a toilet has a dedicated door for privacy. This separate space is set apart from the rest of the bathroom, allowing someone else to use the shower or sink. In some instances, there is also a small sink in the water closet for added convenience. The main benefit of a water closet is that it offers private space and can be a desirable design amenity, particularly if the bathroom is shared with others.

Main water shut-off valves last 10 to 20 years on average, though they can sometimes last longer. This depends in part on the material you choose. Brass valves are very durable, but more expensive bronze or stainless steel valves may last even longer. Main water shut-off valves often fail due to aging internal parts, such as rubber washers. However, corrosion and sediment buildup also contribute to valve failure. If purchasing a home at least 10 years old, you may want to replace the main water shut-off valve soon to avoid potential problems.

It is generally recommended to schedule a professional plumbing inspection annually, though an inspection every two years may be sufficient for newer homes. The ideal frequency depends on several factors, including the age of your plumbing system, water quality (such as hardness), and any previous plumbing issues. More frequent checks are advisable for older homes or those with a history of problems. Additionally, if your property has mature trees with extensive root systems, more frequent inspections are beneficial as roots can crack sewer and water lines. Regular maintenance helps identify potential issues early, preventing costly repairs, and can include checking for leaks, inspecting connections, and ensuring pipes and fixtures are in good working condition to prolong the life of your plumbing system.

There are three main types of shower valves: pressure-balancing, thermostatic, and diverter. Pressure-balancing and thermostatic valves are both considered mixing valves because they regulate water flow and temperature, but they do so in different ways. A pressure-balancing valve senses changes in water pressure, such as from a flushing toilet, and adjusts the incoming hot and cold water to maintain a consistent temperature; these typically use a single knob. A thermostatic valve uses a thermostat to precisely control the water temperature and requires a separate control to adjust the water volume. A diverter valve directs the flow of water from one fixture to another, such as switching from a tub faucet to a showerhead in a tub-shower combination.
