Less waiting, faster turnaround.<\/p>\n<\/div>\n<div id=\"wb-faq\" class=\"wordbank-container\">\n<h2>Frequently Asked Questions<\/h2>\n<div class=\"faq-accordion\">\n<div class=\"faq-item\">\n<h3><button aria-expanded=\"true\" aria-controls=\"faq-content-0\">Should I degrease or rinse the unit first?<\/button><\/h3>\n<div id=\"faq-content-0\" class=\"faq-content\">\n<p>Send the unit in whatever condition it&#8217;s in. We clean everything during teardown before inspection begins.<\/p>\n<\/div><\/div>\n<div class=\"faq-item\">\n<h3><button aria-expanded=\"true\" aria-controls=\"faq-content-1\">Is it helpful if I include photos before sending the unit in?<\/button><\/h3>\n<div id=\"faq-content-1\" class=\"faq-content\">\n<p>Yes. Photos of the nameplate and overall unit let us begin identification before it arrives, which speeds up the process.<\/p>\n<\/div><\/div>\n<div class=\"faq-item\">\n<h3><button aria-expanded=\"true\" aria-controls=\"faq-content-2\">Is there a warranty on repairs?<\/button><\/h3>\n<div id=\"faq-content-2\" class=\"faq-content\">\n<p>Warranty coverage of a 12-month warranty on parts and labor is included with every repair we complete.<\/p>\n<\/div><\/div>\n<div class=\"faq-item\">\n<h3><button aria-expanded=\"true\" aria-controls=\"faq-content-3\">Is it possible to repair a unit without full labeling or ID?<\/button><\/h3>\n<div id=\"faq-content-3\" class=\"faq-content\">\n<p>Even if the tag is worn off, we can often match the unit based on shape, size, and internal configuration.<\/p>\n<\/div><\/div>\n<div class=\"faq-item\">\n<h3><button aria-expanded=\"true\" aria-controls=\"faq-content-4\">Is it better to refurbish or buy a new unit?<\/button><\/h3>\n<div id=\"faq-content-4\" class=\"faq-content\">\n<p>In most cases, repair costs less than replacement, especially for legacy or OEM-specific models. We evaluate every unit and let you know what makes sense.<\/p>\n<\/div><\/div>\n<\/p><\/div>\n<\/div>\n<div id=\"wb-process\" class=\"wordbank-container\">\n<h2>Rebuild Steps<\/h2>\n<p>The process begins with disassembly and visual evaluation. We then clean, replace worn pieces, and reassemble the valve to restore its function.<\/p>\n<ul>\n<li>Cleaning: Units go through a mineral bath, with ultrasonic cleaning used for delicate internals.<\/li>\n<li>Leak and Pressure Testing: The reassembled unit is leak-tested and pressure-tested to verify it meets published specs.<\/li>\n<li>Seal and Gasket Replacement: Worn seals and gaskets are replaced with new components during every rebuild.<\/li>\n<li>In-House Parts Sourcing: Many repairs use components sourced from our inventory of 17,000+ units.<\/li>\n<\/ul>\n<\/div>\n<div id=\"wb-testing\" class=\"wordbank-container\">\n<h2>Leak and Performance Testing<\/h2>\n<p>We carry out full diagnostics on every valve, including flow gain, leakage, pressure shift, and frequency testing.
