If yours is a closed <a href=\"https:\/\/www.isaacheating.com\/rochester\/plumbing\/\">plumbing<\/a> system, an expansion tank is an essential safety device. Without one, your home could suffer leaks or even burst pipes in extreme cases. An expansion tank&#8217;s role is to relieve excess pressure in your plumbing to prevent those issues.<\/p>\n<p>Typically, you&#8217;ll find an expansion tank installed along the cold water line that feeds your water heater. That puts it in a perfect position to handle overpressure events in your plumbing. If your home requires one, our expert plumbers can install it with minimal disruption.<\/p>\n<div class=\"h6\"><strong>If you need an expansion tank in Rochester and don&#8217;t have one, issues may include:<\/strong><\/div>\n<ul>\n<li>Premature water heater failure<\/li>\n<li>Plumbing leaks<\/li>\n<li>Water hammering<\/li>\n<li>Decreased plumbing system lifespan<\/li>\n<\/ul>\n<h2>Expansion Tank Replacement<\/h2>\n<p>With an average lifespan between five and 10 years, expansion tanks frequently require replacement. However, it isn&#8217;t always immediately obvious when the time has come. One way to find out is to schedule an inspection by our thermal expansion tank service specialists. We will test your expansion tank to determine whether it needs replacement. Otherwise, there&#8217;s a simple way for you to check the condition of your expansion tank. It&#8217;s not a substitute for professional diagnostics, but it is useful nonetheless. To do it, knock on the side of your expansion tank. It should emit a hollow sound if it&#8217;s in good working order. If you hear a dull thud instead, contact us for thermal expansion tank service.<\/p>\n<div class=\"h6\"><strong>You should also look for the following signs that may indicate the need for a new expansion tank:<\/strong><\/div>\n<ul>\n<li>Tank is over 10 years old<\/li>\n<li>Rust or corrosion on the tank<\/li>\n<li>Tank requires frequent repair<\/li>\n<li>Tank shows signs of leaks<\/li>\n<\/ul>\n<h2>Expansion Tank Repair &amp; Diagnostics<\/h2>\n<p>In most cases, the simplest solution to an expansion tank issue is to replace it.
