I'd love to have my plumbing checked once and then never think about it again. Do the repairs and not have to come back to it for another 20 years. Unfortunately, everything wears out, gets old and deteriorates, even if high-quality materials are used. Especially when it's something that's actively used every single day. I'm all for services like the ones Ben's Plumbing https://bens.plumbing/blog/seasonal-plumbing-checklist/ offers, namely seasonal maintenance and inspections of plumbing, pipes, and drains. Repairs are especially common after winter, and it's better not to miss the moment when it's time to take care of them.
