The first in last out method of piping unites has been around for a long time but in my research of piping the system I found it was overlooked.
As I explained in the video we learn from our mistakes and the way I piped in that system proved it, after it was fixed it worked perfectly.
If you would like a piping diagram, please e mail me your info to economyplmbg@aol

If you would like to buy the filter removal tool, please e mail me at [email protected] and include your complete name and address.
I hope you enjoy the video,
Mike
