Re-pipe - DF

Dan Foley

We re-piped this five year old system a couple of weeks ago. It is located in Winchester, VA - about an hour West of DC. It is well outside of our service area but we did this to help out a good friend - our Heatway rep.

When I surveyed this job in early January, it was 49*F in the main part of the house and 64* in the master bedroom - with the help of some portable electric radiators.

Here is the "before" photo:

Cleaning

This is what came out of the system after we cleaned it with Rhomar Hydro-Solv 9100 (thanks, George!). The tubing was Heatway Onyx in a gypcrete thin slab. -DF

looks like

water from a wet-based sprinkler system(G). Those Brutes make for a very nice installation. We've grown fond of them too.

As always, great looking work!

Looks like

you built an independant primary loop, added a 3rd mix valve and upsized the piping. Nice work.

What are the designed supply temperature ranges and did you increase supply temperature to any of the zones?

That color water may indicate your Weil GV, and other ferrous components have been rusting, did you add any inhibitors?

Gonna have any more design days to test out the upgrades?

Nice job Dave.

That goo looks like what I pull from a coil flush on any indirect. It is LIFE!!!

How did the original installer intend on freeing the btu's through 3/4 primary pipe? Magic? Nice work . Chris

Thanks for the comments, Dave. The nasty stuff that came out appeared to be a mixture of iron oxide and sediment. This system is on a well and it appears the initial fill was done before the well water had a chance to "settle".

Hi Hot Rod,

You have a good eye! We piped a true primary loop. The existing primary pump was burnt up from dead-heading as the thermostatic bypass valve in the GV closed. We isolated one staple-up zone on its own mixing valve and it operates at 135*. The master bedroom (gyp) is on its own mixing valve and operates at 115*. Two additional gyp zones share a 1" mixing valve at operate at 105*

We added Rhomar inhibitor to the system after we cleaned it to help limit the corrosion.

The weather here is still chilly but it is unlikely we will see single digits again this year. -DF

Thanks...

Hi Clammy, thank you for the kind words. We do like the Webstone flanges and buy them by the case. -DF

It's Dan!

Hi Chris, It's Dan! But then again, I have been called worse so I'll take it:)

The existing 3/4" primary loop did not allow enough flow to distribute the heat out to the zones. We beefed it up to 1". In addition, the strainer, air separator and mixing valves were fouled up with sediment and iron oxide.

Note that the three pumps on the existing 3/4" mixing valve feed three manifolds with a total of 19 3/8" loops. That is a classic case of "heat constipation". We split one manifold off on its own mixing valve and upsized to a 1" valve for the remaing manifolds. -DF

Hey Dan

Looks good. Are those Comberio ball valves I see. Where do you get them? Do you have to order them in, or are any supply houses carrying them? What was the main problem with this job? Was it undersized piping or low water temps. I see you added a mixing valve so more temps are available. WW

Sorry DAN,

Lazy Saturday morning and the coffee hadn't kicked in yet. OOOPS Chris

How did they last

five years with a system that performed so poorly?

Constantin

Darn fine work...

... it's amazing what a difference "subtle" changes in near-boiler piping can make. The pictures speak for themselves, your complete re-work of this critical area is a work of art. The representative and the customer must be delighted...

Congrats again. I have the feeling the representative will be tapping your shoulder and/or pleading on his/her knees in the future as well.

Hello Dan....

It looks miles better. dragging the water to a site is a PITA however comming back to that stuff floating around in the system er dont really appeal to me. This is a harmless question is there a reason that you dont use a check on the return to the primary on your three ways? the other thought i had was if the water is that good and i was buyin where would you place a strainer other than the one in the fast fill?

Nasty Water

Nice job Dan--- On well water you must be in Frederick Cty Va.
Mostly shale ground with nasty water. The city water (river) is loaded with lime and clorine. Best wishes J.Lockard

Beautiful Repipe.

This proves that just because the piping looks pretty on the wall, doesn't mean it works correctly.

Excellent, well thought out repipe.

What is that white blanket-like stuff on the wall?
