New appliances can cost lots of money. Speaking as a homeowner who recently bought a new washing machine and dryer and one who will probably have to buy a new dishwasher before the end of the year, I can tell you this from personal experience. But speaking as a representative of the world’s largest plumbing repair service, I can also tell you that you should make a few improvements on new appliances before you hook them up in your home. Our plumbers see lots of water damage and much of it is caused by cheap, unreliable water supply lines and valves.
Most of today’s appliances are super reliable and technologically sophisticated. As a result, most folks can’t handle their own appliance repairs by themselves. But there are some things that the average person can do and should do at the time of installation. I can sum it all up in four words: braided stainless steel hoses. You can buy braided stainless steel water supply hoses for your washing machine, your dishwasher and your refrigerator’s water supply line. Yes, they definitely cost a little more than the plastic or rubber lines and hoses that come with your appliance but they are worth every penny. Steel hoses will outlast plastic and rubber by many years and they’re far less likely to spring a leak and flood your home. An appliance flood could easily cost you tens of thousands of dollars in repairs to your home. The hoses will only cost you a few extra bucks.
There is no substitute for reliability and if you want long-term peace of mind, disconnect the cheap water lines that the manufacturer included with the appliance and go immediately to your local home or hardware store and buy braided steel hoses of the same length with the same connection ends. Be sure they’re actually steel hoses because I’ve seen braided plastic lines that look like steel but aren’t as good aren’t as reliable.
If you have to replace your water heater, unscrew the plastic drain valve at the bottom before you hook up the water heater. Take the drain valve to the hardware store and buy a high-quality brass drain valve of the same size and type. Wrap the threads with Teflon tape then thread the valve onto the water heater tank. I can’t tell you how many times those cheap plastic valves break apart or go bad within a few short years.
