Are Saddle Valves Against Code

I blogged about how saddle valves are illegal products in Minnesota nearly five years ago, but it's time for an update on that topic with some more information. These are devices that allow for a very fast, cheap, do-it-yourself installation of a ¼” water supply line, typically used to supply water to ice makers and whole-house humidifiers.

The needle just pokes a hole in the pipe, and I've heard it can be done without even turning off the water... not that I've ever tried. These saddle valves are prone to leakage, and they're not allowed by the Minnesota State Plumbing Code.

There is actually nothing in the Minnesota State Plumbing Code that specifically prohibits these types of valves ; they're just not approved. Section 4715.0420 of the MN State Plumbing Code gives a list of approval standards.

When installing an ice maker or whole-house humidifier, tap off of an existing water line with a proper tee fitting and have a proper shutoff valve installed. There has been a saddle valve installed for the ice maker at my own house since I moved in over four year ago.

I haven't touched it and it hasn't leaked, but I thought this would make for a nice little project where I could lay out the basic steps of replacing a saddle valve. To replace a saddle valve or tee off an existing water line, start by obtaining the needed parts.

I'm assuming the saddle valve is connected to a ½” copper water line. If you're comfortable soldering copper tubing and you already have the equipment to do it, this project will cost about $10.

Push fittings are extremely easy to use, requiring no special tools to make connections to copper, Ex, or CPC tubing. This should leave a small gap in the water line, which you'll bridge with the tee fitting.

They are most commonly installed for ice maker lines or under-the-sink water filters. The handle is twisted until the pin inside lowers and pierces the copper pipe.

The rubber line for the ice maker or water filter is then fastened into the nut. The handle is twisted again until the pin is removed from the copper pipe.

Once the faucet is turned on, water will flow through the copper pipe, out the pinhole and through the ice maker line. Leaks create corrosion to the rest of the plumbing system.

Leaks also cause extensive damage to cabinets and flooring. Since saddle valves are often located in places where they get bumped or moved, the chance of a leak increases.

Even though it’s compatible with your electrical panel, chances are you’ll fail the inspection. The National Electrical Code has changed and now requires arc fault protection in all living spaces.

If you really want to burn down your house, pick up a section of this cheap PVC and use it to vent your dryer. If you want to do it the right way and reduce lint buildup, skip the flexible venting altogether.

The code now requires wet-while-in-use covers that prevent water from reaching the outlet while a cord is plugged in. Family Handyman Home centers sell boatloads of these, but they don’t meet current building code.

TRy outlets have spring-loaded shutters that don’t open unless all three plug prongs are inserted at the same time. The lockout feature prevents kids from jamming scissors, screwdrivers and other pointed objects into the outlet.

Well, statistics show that every year around 2,400 kids are burned and shocked severely by the older outlets, and six to 12 of them die. So make your home safe for them and meet code at the same time by installing TRy outlets.

Family Handyman Let’s be clear; non-interconnected smoke detectors aren’t illegal per se. Divers buy them to eliminate the hassle of running a vent line.

But air admittance valves don’t meet building code in most cases. If you install one without checking with your local building inspector, you’ll probably not pass inspection and have to take it out.

Even if you don’t pull a permit, installing an air admittance valve instead of a vent line can come back to haunt you when your home is inspected before you sell it. Some inspectors will allow an air admittance valve for an island sink installation, but others won’t.

But, if you buy a hose BBB with a built-in vacuum breaker, you just pop the cap and replace the internal parts. Many building codes don’t allow whole house fans because, well, they kill people.

In other words, the fan creates negative air pressure inside your home and that’s what pulls carbon monoxide down the flue, dissipating it throughout your house.

In fact, the type of joist hanger allowed by your local building code depends on the type of treated wood you’re using (alkaline copper quaternary, or Act, and copper above, or CA) and the local environmental conditions. In other words, the triple-dipped hangers may be fine for interior use, but fail a deck inspection.
