[Board] 4064 South Hudson Way

Keith,


The tee connection is not harmful to the District or the homeowner.  They function fine and are an acceptable connection in other jurisdictions.


We prefer wye connections vs. tee connections since the wye adds a 45-degree angle when discharging into the main.  A tee discharges into the main at a 90-degree angle.  It's a small difference.


Kind Regards,

Steve? Chris?? as above, what are the failure modes? Can this damage the system, or "just" result in more problems for the homeowner?

CHNMD Board of Directors,


On Thursday September 29 at about 3:45pm, I received a phone call from Scott Cutting with Plumbline Services.  They were finishing a sanitary sewer service replacement at the referenced address.  Scott explained that there was some confusion with which sanitation district held jurisdiction and that is why he was calling at the end of the work.  He asked if I could come out to the address immediately to inspect the service line, but I was unable to do so as I was leaving work for the day.  I asked him to email me pictures and to install a WYE connection at the main.  He agreed.


Scott emailed me pictures a few minutes later, but I had already left the office for the day.  Upon opening the email on Friday, I noticed that Plumbline Services installed a TEE connection at the main in lieu of a WYE (see attached photos).


Overall, we are unhappy that Plumbline Services did not notify us for an inspection 48 hours prior to the work and that they used a TEE connection in lieu of a WYE.  The project is already backfilled & compacted.  We believe a TEE connection will still function adequately despite being outside of specifications.


Please let us know if you have any comments or require any action as a result of the work.


Kind Regards,
