Over the past few weeks I have been working for a plumber friend. He has moved his business to focus on back flow installation and testing. Now after an out break of legionnaires disease that occurred in a chiller in an apartment building that was cross conected to the domestic water, the NY heath dept. is cracking down on all the commercial buildings that don't have RPZ's.

We recently did an install on a restaurant. we put in two new meters, 1 RPZ for the toilets and wash sinks, 1 RPZ for the fancy Tensui water filter, and 1 rpz for the irrigation.

It has been a good experience working with him and learning all the rules on how to install the assemblies to code.

Our codes require that if an RP is in the building, it must have a catchment attached to the bottom and pipe going from it to a floor drain. We have a few that are set up like this, but not many.

the same goes for here. but what you cant really see in the pic is that there is a 4'x4'x3' cement block barrier with a gravel base that drains out. the Water Authority also accepts this method for areas with multiple assemblies

Good Job! Looks Great!
That's a good size drain for inside too.

No air gap drains for the reliefs? Sure would not fly around my area, inside or outside. Our code calls for 2" mininum pipe to sump.

2 " gap here as well.

The least you can do is install gap drains to all 3 and just tee the 3 together down to the drain.

Monster, did you work for free for the knowledge and as a friend? Or did he pay you. Looks like a lot of good knowledge either way.

I am getting paid. He also does regular plumbing. This past week in the same restaurant, we re-piped all the waste lines for the kitchen and bar because they were all pitched the wrong way because the main 6" cast iron sewer pipe came in the building 1" from the floor joists so that had to be changed as well

Did you ever go to any of 'The Group' cross-connection meetings?

Anyone here ever use those Conbraco RPZs? It kind of looks like their placing a testcock on the lower part of the relief valve assembly might get around the necessity to dismantle the thing each fall.

I have one customer with it. Not sure where it came from. probably a plumbing supply house.

Was thinking of checking pricing on those just because they are American made, to the best of my limited knoledge.

I used to buy their Apollo ball valves, since they had longer handles than the competition. Their PVB is the old Watts 800.

Thats why I thought I would share. But the inforcement of irrigation back flow is still pretty weak.

I Haven't . But I just got a letter in the mail saying they are holding a meeting in Bellevue for all Backflow testers. cross connection control specialists and a few others coming up in about 2 weeks.

I will attend that.

I like that in the letter they refer themselves as " The Group "
