    Pool People.........

    What are they good for?

    I think that was a song in the 60's. Anyway ran across this today on one of my indoor pool heat pump people. Pump was just repaced by the pool guy. Never knew this kind of fitting existed.

    I'm made my share of money repiping the pool people's piping, especially on the pumps.

    It's proper and necessary to run a length of discharge pipe at least 3 times the size of the discharge opening before a bend is made. This allows the water to someone stabalized before causing it to go through a turn.

    I've repiped so many systems that were piped this way and have reduced the amp draw of the pumps motors as well as made the heat exchange in the heat exchanger much more productive.

    PVC is dangerous in untrained hands. It makes anyone feel like they can be a plumber
    Last week I re-piped this lobster tank in a supermarket

    I suspect there were more linear feet of fittings than pipe.
    Unfortunately I don't have any after pictures.
    sorry the pics are sideways

    These pipes were connected to the wrong ports on the filter, they needed to be switched.

    Someone has stock in PVC fittings from the look of your set up.

    Take a look at my first pump picture and you will not see any glue or cleaner on the first two joints. I can't see how the joints are kept together. I decided not to mess with it as I'm not the one who installed the piping by the pool pump people presently presented PVC piping pictures.

    PVC:

    I always use clear cleaner and clear cement. You can always tell if the pipe and fittings are cleaned. The writing doesn't go into the socket.

    Those are mostly drainage DWV fittings, but Sch 40 pressure rated fittings are what should be used.

    primer and cleaner are chemically different. cleaner should not be substituted for primer. Around here if the inspectors don't see the purple you don't pass the inspection.


    Usually you don't need to use cleaner, but its good to have a can of it around for when you spill the primer and have to get the stains out of the floor

    Primer/Cleaner:

    I use Rectorseal "Big Bill" or "Pistol Pete". One is cement, the other is cleaner. As far as I know, there has never been anything in the Massachusetts Plumbing Code that requires the use of dyed primer/cleaner. Just that it must be cleaned. Charlotte says that it must be cleaned. Any AHJ/inspector that can't tell if pipe and fittings are cleaned, isn't looking. I can tell at a glance if it has beem cleaned with clear P/C. Especially if the manufacturers information line is missing as it comes out of the socket. The P/C is supposed to clean the hard surface on the pipe and fitting that form when it comes out of the mold. The P/C cleaner is to remove the hard surface and clean it off. It is supposed to so soften the pipe and fitting so that the cement can further soften the pipe and fitting for a proper fusion weld.

    I was in Florida and had to fix some broken PVC irrigation pipes for someone. I went to HD and bought some cement and cleaner. All they had was the purple stuff. When I tried to clean the pipe and fittings, it would set up immediately and i couldn't wipe it off with a clean rag. It stayed on the pipe. The cement didn't take it off. IMO, it ends up interferring with the chemical solvent weld. But that's my opinion and I'm sticking with it. I also deburr the pipe so it doesn't act like a squegee and wipe the cement out of the fitting, causing a leak. A common problem for those that don't clean and de-burr.

    Look on Charlottes Web Site. Where they also tell you not to use Sch.40 PVC DWV 1140 pipe and fittings on anything other than drain, waste and vents or Potable Water only and not over 140 degrees. Absolutely nothing about venting heat making appliances.

    Good for you. I'm a mechanical engineer and I have seen some amazingly bad piping over the years. Now I know where I can post that stuff.

    Stupid Rules for Inspectors:

    Another stupid rule for lazy inspectors. All that purple stains on white pipes and fittings make it look like hackaroos were turned loose on the piping, no matter how straight it looks.

    Makes me again realize how grateful I am to be licensed and work in Massachusetts where we don't have a lot of these CS regulatiions. We have a "Uniform Code" that means that the same code regs are the same in Pittsfield as they are on Nantucket. Inspectors are required to get 12 hours of continuing ed per year and we common folks have to take 6 hours per year of we can't renew our licenses.
