Hose bib

This is the page where I show you step by step of how a plumber will remove an old dripping hose bib and solder on a new one. What you will find here is an amazing amount of pictures (approximately 44) so I hope you noticed the warning on the lessons page. The plumber starts out with seeing that the hose bib won't stop leaking when he turns off the handle. When he removes the stem to examine the possibility of changing the washer he notices that the handle stem is slightly stripped and decides it would be better to replace the hose bib than attempt to fix it. In this case the hose bib is the sweat type instead of the screw type.

Highlights of this lesson

Taking the paint off with sand cloth
Water trapped inside the hose bib.
Reaming the pipe.
Supporting adjacent fittings.

turns off the handle, click here to see larger image After he tightens the handle he determines it is not going to stop dripping, heck the customer knew that.

turning off the gate valve, click here to see larger image 1st thing to do is shut the water off to the house so he can remove the stem. If this shut off valve won't do the trick he will need to use the shut off at the meter.
How the plumber will shut off the water from the meter.
How the plumber will drain down the system from the meter.

Okay so he unscrews the packing nut with the blue handled channel lock pliers.

gate valve, click here to see larger image He notices it is still dripping so again he tightens the gate valve to shut it down.

sanding off the paint, click here to see larger image Time to start soldering so he gets out the sandcloth to get the paint off from where he will seperate the existing hose bib.

wetting the sandcloth, click here to see larger image Here we see him getting the sandcloth wet so that it keeps the paint dust to a minimum. This is the beauty of open mesh sand cloth you can get it wet without compromising its performance. Unlike regular sand paper.

bringing out the torch, click here to see larger image The hex part of the hose bib and a spot of old solder is in the way to sand any further so he gets out the torch. He uses map gas and a turbo tip to get maximum heat.

bringing out the sawzall, click here to see larger image Okay this is going to take all day because there is too much water trapped in the hose bib. Time to get the sawzall out and put an end to that little dilema.

diagram of hosebib, click here to see larger image This demonstates a very important plumbing principle. Water seeks it's own level. In other words water will spread out evenly according to it's own mass or supply. So don't ever think that you might just have a little water trapped. You need to look at the piping closely to understand just how much water you may be dealing with in a given situation.

cutting the old hose bib, click here to see larger image Getting through this brass is not tough with a new metal cut blade. Using a reciprocal saw like this one is a science in itself. The biggest tip is not to bind the blade and always use sharp blades.

using the pliers, click here to see larger image Once that is done it's back to the torch and gently using the pliers so that he doesn't compromise the shape of the pipe.

applying the flux, click here to see larger image He prepares the new piece of pipe and existing fitting by cleaning and then brushes on some flux.

cutting the old hose bib, click here to see larger image Rather than configure all of the pieces now he uses a long piece of pipe to make this solder joint. He has to be careful here not to let the pipe sag which will make his solder uneven.

cleaning the excess solder, click here to see larger image Making final touches with a little flux cleaning. Not shown here is the plumber wiping his brush off with a paper cloth so he doesn't get the rest of the can of flux dirty.

cutting the pipe to size, click here to see larger image Now he cuts the pipe to the size he needs to accomodate the fitting that will hold the hose bibs.

cutting the pipe, click here to see larger image Some people call these wheel cutters.

sanding the pipe clean, click here to see larger image Once that is done it's back to cleaning the pipe end with the sand cloth.

getting out the reamer, click here to see larger image Now it's time to use the other part of the wheel cutter. The reamer, to get the grooved part of the pipe out. Leaving the pipe tapered will create turbulance when the water flows through it which will restrict flow and shorten the life of the pipe. This is a big deal folks and a lesson in itself I hope to illustrate in detail at another time. Back to top.

reaming the pipe, click here to see larger image The gloves come in handy here when checking the inside of the pipe because it can be razor sharp.

soldering on tee, click here to see larger image He slips on the tee and it actually goes to far. If the pipe remains in this far it will create problems. Usually there is a built in stop in fittings that won't allow this.

preparing to solder, click here to see larger image He brings it back to where it should be.

putting teflon tape on the threads, click here to see larger image After letting the fittings cool down he applies teflon tape to the threads of the hose bibs before he screws them on.

screwing on the new hosebib, click here to see larger image After screwing on by hand until it is hand tight, he uses his smooth face open end wrenches. One two tighten with the other to hold the other part of the piping so that it doesn't get stressed. This is another big deal. Notice, he does'nt apply pressure to the other fittings when tightening the hosebib.

lining up the hose bib He finishes up tightening the hose bib. One crucial part of plumbing is getting screwed joints tight but not too tight. It would be nice to have calibration tools like mechanics but so far plumbing hasn't been that exact in its techniques. Rule of thumb on fittings this size is using 2 ten inch open wrenches will do it with a maximum of force. Now I know the force will vary with the user but you will know when you can't get another turn out of it and that's where you stop. Somewhere in the unwritten code of plumbing you should give it one full rotation after hand tight but I usually keep going until it stops. There are exceptions to this as when I am working with compression fittings or on parts of a fixture. In those cases I will stick close to the one turn rule, or in some cases 1/4 turn. If there is specific manufacturer's documentation on a specific job the plumber should go by those recommendations.

finishing touches to hose bib, 
click here to see larger image Taking pride in his work the plumber checks the position of the hose bib with a level.

cleaning with a 
paper towel, click here to see larger image Using a mild soap solution and then a clean water rinse he drys the pipe off with a paper towel.
And voila the job is complete.
