"First time they were here. Two young boys showed up. Walked around the house for a little. Claimed they would come back with a video camera to inspect the pipes. That was 3 months ago. THEN they did do a snake in the garage. But, Left all the mess. They didnt not even bother sweeping or wiping anything. The didnt lay anything on the washer for their equipment. So the washer and dryer are scratched up pretty bad. Then when I called to get it rescheduled and handled properly they sent me elsewhere. As a business owner im used to provided a certain level of customer service. Even if the customer is tough or the job is hard I use those times as a chance to show people what i can do. Under promise and over deliver! EDITED Now the young lady who does the texting seems upset and taking what is a professional review, where i have not written anything to Attack personallyâ ¦.now im receiving personal Comments texted to me. With the way things have been going im Not surprised. Its unfortunate to say that Seems theres a genuine coaching opportunity here for joels plumbing."

"We were very happy with Patrick from Overland Plumbing! He was both knowledgeable and professional and completed our valve replacement in less time than I expected. This meant the water didn’t have to be off for hours on end, which was great! Our house is about 90 years old and I suspect this valve hadn’t been replaced in years. Someone came onto the property and managed to break it, causing problems with the water pressure. Replacing it required soldering. It’s great to have our water pressure back to normal. Thank you, Patrick! "

FAQs for water heater installation and replacement projects in Agoura Hills, CA

You'll need an expansion tank if your home has a closed water system, which is standard in newer homes or those with backflow preventers or pressure regulators. Expanding hot water has nowhere to go in closed systems, creating potentially damaging pressure. The expansion tank provides space for this expanded water, protecting your plumbing system and water heater from premature failure. Many local building codes now require expansion tanks, and some water heater warranties may be voided without one.

For a standard 50-gallon water heater, a two-gallon expansion tank is sufficient. This sizing assumes normal household water pressure between 40 and 60 psi. If your home has higher water pressure (60 to 80 psi), consider upgrading to a slightly larger tank for added protection. The expansion tank's purpose is to accommodate the increased volume that occurs when cold water heats up, which is proportional to your water heater's capacity.

Watch for signs like dripping water around the tank, fluctuating water pressure throughout your home, or unusual noises in your plumbing system. A properly functioning expansion tank should feel light when tapped on the bottom—if it feels heavy or waterlogged, the internal bladder has likely failed. Other indicators include frequent triggering of your temperature and pressure relief valve, visible corrosion on the tank, or unexplained increases in your water bill, suggesting hidden leaks.

Most expansion tanks have a service life of five to 10 years, though some may last up to 12 years or more with proper maintenance. Factors affecting lifespan include water quality, system pressure, installation quality, and tank construction. Hard water areas often see shorter lifespans due to mineral buildup. Regular maintenance checks can help identify potential issues before complete failure. When your water heater is due for replacement, it's wise to replace the expansion tank simultaneously, even if it hasn't failed yet.

A 30-gallon water heater needs an expansion tank if your home has a closed plumbing system. The need for an expansion tank is determined by your plumbing system type rather than water heater size. Even smaller water heaters create thermal expansion when heating water. If your home has a backflow preventer, pressure regulator, or check valve on the main water line, you have a closed system that requires an expansion tank. Check your local plumbing codes, as many jurisdictions now mandate expansion tanks regardless of water heater size.
