Get the lead out

Unsurprisingly, another year has passed and we are on the brink of 2014.  Hopefully the new year will be filled with new adventures, happy times and will create some wonderful memories for you and your family. Unfortunately, it will also be filled with a new hidden tax that will be passed on to you, the consumer, by way of more expensive plumbing supplies and fixtures.  In the government’s never ending quest to protect us all from ever dying, we will be faced with yet another regulation.  This time the enemy is lead.  This is by no means intended to be a political post, or even a medical one, as I am ill suited to properly explain either.  What I am intending to do, is simply pass along this new regulation that we as plumbers will be forced to follow by law (and maybe point out some of the silly aspects of it).  While I am obviously not opposed to making things safer, I am opposed to laws that have many foolish facets and do not seem to be properly thought out.  

Beginning January 4 2014, any product that comes in contact with the potable (drinking) water system must not have a lead content exceeding .25%.  All plumbing materials and fixtures must be NSF 372 certified in order to be code compliant for potable water systems.  This is mainly going to effect brass.  The lead in brass will now need to be substituted with a different allow, and all of these new alloys will be more expensive than the lead.  This means the cost of anything plumbing related that contained brass will be going up.  In most cases the cost increase will be anywhere from 15-30%.  Some faucet manufacturers have simply decided to abandon almost all brass in favor of plastic.  This is the reason most new faucets appear to be very cheap and flimsy, because they are!  Some manufacturers have opted to retool their factories and stick with brass, but rest assured, that cost will be passed on.  

While most of this appears to make sense, it is a blanket law covering all plumbing materials. Exceptions have not been made for specific items that would not ever leach lead into waters that a person would drink.  A few of these items that will be covered by the law are irrigation backwater valves which serve ONLY your sprinklers.  A hot water vacuum breaker, or temperature and pressure relief valve.  The last time I checked, most people did not drink hot water, and even if they did, these two items barely have any surface area that even make contact with the potable water system.    

The law may get even more silly when the inspector mandates that the new valves on your bathroom remodel be NSF 372 certified, but he fails to mention that your water MAIN coming into your house is a LEAD PIPE!  Of course, this only applies if you live in an old home, most likely downtown.  

Merry Christmas everyone!  Your new year MAY be blessed with a .000025% less likely chance that you will develop lead poisoning, while your plumbing WILL be going up by about 25%.  

Could you please pass the dope…

PictureApplying thread paste (pipe dope)

There are many different products available for use in the plumbing trade.  These products can range from harmful, to questionable to necessary.  There is also a lot of confusion about which product to use, when to use it, and where to use it. 

Below is a list of the most common products, with a short explanation of each one.  


1. Thread paste.  Also called “pipe dope”, thread paste is probably the most used product on a plumber’s truck.  The main function of pipe dope is to seal threaded connections by filling in the tiny voids.  Applying the paste will also act as a lubricant and help to tighten the connection a little better.  There are many different kinds of thread paste on the market, and some contain different chemicals.  You should always be sure that the paste you are using is ok for the material you are using it on.  Some pastes should not be used on plastic threads.  There are a few other situations that plumbers like to apply the paste, such as on the mating surfaces of certain kinds of unions, inside compression fittings, inside flared connections, or on the bottom of certain types of gaskets.  

2. PTFE Tape.  PTFE (polytetraflouroethylene) tape, or thread tape, is commonly (and mistakenly) called Teflon tape.  Since Teflon is a trademarked brand of the DuPont corporation, this product should not be called “Teflon tape.”  On threaded connections, PTFE tape can be used in place of, or along with pipe dope.  I don’t really have a preference either way.  If it is a connection that I most definitely do not want to have to fix, I will usually use both.  There are also certain devices that will call for tape specifically because it can be harmful if paste is introduced into them when the water is turned on.  It is important to not “overwrap” the threads with the tape, as this could possibly result in putting too much stress on the female fitting and crack it.  

3. Plumber’s putty.  This is probably the most widely misused plumbing item there is.  There are many times that I come across putty being used in place of paste or tape, and that is always a sure fire leak.  Putty should only be used on the underside of something that will be tightened or compressed down, such as the underside of sink drains, shower drains, and bathtub drains.  Some plumbers will use it underneath stainless steel sinks to seal them to the countertop as well. In the old days, it was used to seal toilets to the toilet flange at times.  

4. Latex caulk and silicone caulk.  Caulks and silicones should never be used to seal any piping.  They should only be used to seal fixtures down, or seal around areas that should not allow water in.  Examples includes, caulking down sinks, tub spouts, outside penetrations, maybe even faucets.  Some plumbers like to use silicone on the underside of sink, shower and bathtub drains in lieu of plumber’s putty.  I do not recommend this for two reasons: 1. It is very messy, and 2. If you ever have to remove it, good luck. 

5. Plumbers grease.  Any time you take a faucet apart, grease up everything!  This includes O-rings, threads and any moving parts. 

6. Flux.  Flux is what you put on copper or brass pipe to prepare it to be soldered.  It cleans the pipe and allows the solder to “flow” into the fitting. 

7. Draino.  Don’t use it, ever.

Two days in the life of a plumber

Picture

Sometimes in the plumbing profession, things go smoothly, and according to plan.  Other times, or rather, MOST of the time, things always seem to go a little sideways.  We recently got an email from one of our most frequent and best customers explaining a few minor plumbing jobs that needed to be done on a newly purchased property.  On these older homes, it is always a good idea to take a look at them to see what we would be getting in to.  The list seemed simple enough- new toilet seat, disconnect gas line to stove and add a shutoff valve, replace kitchen sink and faucet, and replace the bathtub faucet. All of these items were pretty simple on their own, and I had explained that it should be possible to stay within his budget.  The next day I started the work and it wasn’t until I headed downstairs that things got interesting.  I noticed a few additional problems pretty quickly, such as a rusted-away tub drain and a few water lines that had been split.  Even these few problems that were visible where not enough to cause too much concern.  I promptly made my way through all of the problems that were noticeable.  All of these issues are pretty common with older homes, especially with the old galvanized steel water lines and cast iron drains.  When everything APPEARED ok, I slowly started to turn the water on, and this is when the fun began.  Within seconds, a slow drip developed, right next to my head.  The galvanized pipe was split on the seem on the top of the pipe.  Water off, repair made- #1.  When that was fixed, it was now time to try again.  I slowly turned the water on, and a little bit further down the line, I see water pouring onto the floor.  This time there was a crack in the threaded portion of the pipe.  Water off, repair made- #2.  This pattern continued for no less than 6 repairs before I eventually had to call it a day and plan on a round 2 the next day.  By the time I was able to get the water on, 75% of the house had been replaced with pex water lines.  On day number two I eventually decided to cut my (his) losses and simply start cutting most of the old water lines out.  There were a few lines that remained in the walls that were copper, so those remained in tact, even though a few of the fittings had blown apart.  What appears to have happened in this house is that it never got properly winterized and literally EVERYTHING froze, EVERYWHERE.  Now that the water was on, I had a slight bit of optimism that I was almost going to be able to get out of there.  Of course this was not the case because we are dealing with old plumbing.  The toilet would not fill at all due to a completely corroded galvanized line serving it.  I had to turn the water back off, and run a new line with a new shutoff valve to the toilet.  After the toilet was working, I turned the water on at the dual lavatories and the faucets both worked great, to my surprise!  What I was not surprised by though was the fact that the water did not go down the drain AT ALL.  After pulling the p traps off both lavs and snaking the main drain serving them, I got all of the water to go where it was supposed to.  I was even lucky enough to find a handful of hair ties, straws, toothbrushes, and toys along the way.  If you are ever considering purchasing an older home for yourself, to flip or to rent out, keep your plumbing budget plenty high in case of unforeseen problems, which are almost always going to be there.   Allow a professional plumber to take care of it for you, and save yourself days, weeks or even a lifetime of plumbing headaches.
