Greetings everyone,

First of all, I would like to apologize for not sending out a newsletter for May.  There just wasn’t much to report on.  I received the treasurers report and put it on file, and the rest of the morning turned out to be the kickoff meeting for the October seminar.  Some folks wait for the newsletter to get the link for the next meeting.  Please make a note that it is a reoccurring meeting and is the same every time. The Group is inviting you to a scheduled Zoom meeting.  Our meetings are usually in Zoom format from 10:00AM till 12:00 PM every third Wednesday of the month.  The exceptions obviously are the August picnic and the October seminar.  Feel free to join in if you’re interested.

We would like to introduce our new webmaster Paul Molisani.  He owns a software company and works out of Portland Oregon.  Paul has been a Group member and follower for quite some time and has volunteered to take over the Group Webpage.  So expect some changes and some updates.  Thanks to Paul for his donation of time to our Group.

The Group officers and some members met on June 15th via Zoom.  There was some discussion regarding fire systems specifically the flow-through designs.  We have been trying to find an expert on the topic to attend a meeting or even host at the seminar, but so far there has been no success: ☹.

Orange CPVC piping is the most common piping utilized in these systems.   It is designed for potable use.

NSF International, an independent, not-for-profit organization, helps protect you by certifying products and writing standards for food, water, air and consumer goods. BlazeMaster is NSF International certified for potable water conveyance per NSF/ANSI 14 Plastics Piping System Components and Related Materials & 61 Drinking Water System Components – Health Effects.

Who has the authority, approves, and inspects new flow through systems?

We had many more questions than answers.

I can speak for the City of Redmond since our fire standards for residential buildings have gone through three design changes.  First, we had one meter with a manifold behind the meter. One line for domestic and one line for fire.  The doublechecks landed in the garages, which wasn’t exactly what we wanted and made testing more difficult.  We called this Dual-Use metering.

The next design was a domestic and fire manifold that consisted of one meter for domestic and usually a larger one for fire.  The double check could be in the ground behind the manifold or again, in the garage.  This was also problematic for the water department.  Also, the homeowner had the ability to shut their fire system off. (And leave it off). (Fire suppression meter)

Next came the flowthrough systems.  One meter, all potable piping.  I can say that I have never received a taste or odor complaint from a customer with this system in place.  If the flowthrough systems were approved before all of the other ideas, Redmond would have about 1,200 less doublecheck to track yearly.

At this link, you will find the NSF Product and Service Listings.  You may find it helpful if you are dealing with these types of systems.   “Plastic Piping System Components and Related Materials

So, that was about it other than more planning and seeking out guest speakers for our October event.

It seems that we will have some good ones!  More to follow later in the year when we have everything finalized.

With that I will close.  Please shoot me an email if you have any questions or anything to share with the other members.  See you at the virtual July meeting!
