Don’t Poke Holes In Your Pipes

Most ice makers and whole house humidifiers that I see have a saddle valve supplying the water. These are devices that allow for a very fast, cheap, do-it-yourself installation of a ¼” water supply line.

Saddle valves are installed by tightening a metal clamp on to a water pipe, then tightening down a needle valve until it pierces the water pipe.  No cutting of pipes is required, no soldering, no special tools… simple.  Very DIY.  The needle just pokes a hole in the pipe, and it can even be done without even turning off the water (but I sure wouldn't recommend it).  There has to be a catch, right?

Saddle Valve

There is.  They leak, and saddle valves are prohibited by the Minnesota State Plumbing Code.

Most of them don’t leak, but they have a much higher chance of leaking than a properly installed water valve.  If they do end up leaking, the repair will involve doing all the stuff that you’re supposed to be able to avoid – cutting, soldering, etc.

My advice is to not use saddle valves.  If you’re installing an appliance that needs a ¼” water pipe, have a proper shutoff valve installed.  It will certainly take more time, but you'll dramatically lower the chances of it leaking.

If you already have one in your house, try to leave it alone.  Every time you operate the valve, you’re increasing your chances of creating a leak.

Sounds like the perfect solution for the oil spill in the Gulf. . .

Interesting. Never knew this but it does make sense.

It's never worth the cost of an inferior solution especially when mixing water and the interior of your house

enjoy the day

Reuben, good post----I WISH they were not allowed out here :)  Reuben here is the "question of the day."  Why are things that are not approved in a given area, for sale in the same area?

Fernando - they just need a really big one, right?

Pat - just look for 'em.  You'll start seething them everywhere.

Don - solid advice!

Charles - that's a great question!  That sounds like a good future blog topic, thanks for the idea.

Good post Reuben.  I did not realize there was such a problem with those type of quick fixes. 

What do you think of gator teeth (also called shark teeth depending on the manufacturer)?

Hi Aaron, I really don't know much about gator teeth.  I've heard they work well, they're approved for use here, the fittings are fast and easy, and they're really expensive.  That's about it.
