Faulty Pipe!

Need we say more! A picture is worth a thousand words.

Very very nice ....

that looks well thought out. i like your use of swoopin Uies:)

Jamie,

First thing the panel looks great.I was wondering what was happening with the rubber tube?Was it breaking or cracking?I'm sure you are more than aware of the class suit.Did the HO persue this?If so how did it fall together?

Great job...

If'n it were me, I'd have flipped the S&R manifolds upside down and eliminated all the beautiful hard work you put into the U turns.. But thats just me. The older I get, the lazier I get:-)

My guys like it when I design and lay out a job due to my laziness...

Were the hoses showing brittleness near the supply manifold connections?

where did you get those black straps for the pex$

Hey Mark,

Wirsbo says in the instructions that you are not allowed to turn these bad boyz upside down.

Mike,

The homeowner had many calls into Heatway but just kept getting knocked around. After 4 years of calling and no response he called the RPA and they gave him our name. We are not that familiar with heatway products nor the class action suit, but I will pass this information on to the homeowner.

Would you please e-mail me the attachment you posted (it is printing too large on my paper) so I can pass it on.

Thanks,

Jamie

Guess...

I ought to follow my own instructions and read the directions more often.

Come to think of it, when I've done it that way I was using one zone valve to control the manifold, and not multiple telestats. Guess they're worried about either heat build up or water dripping into the motors.

Maybe one of the Wirsbo folks will drop in and tell us why...

My bad..

manifolds

I'd turn them sideways so you only have to make a 90 instead of the full 180. Even that makes it easier, and in my opinion it's a little cleaner, especially with bend supports.

Question

first, nice work on the redo. It looks first class.

Wondering what model that tube is. Typically white lettering is post E2. It should have a name and date code somewhere.

What exactly was the reason for the replacement? Thanks

the flow indicators dont work right

on these if you flip-em

also i thought i was good practice to always loop feed from the bottom of Hydronic applications to get the added benefit of a heat trap, this becomes really important if you don’t have zone valves – just flow controls on radiant manifolds – or have the zone valves on the return side with baseboard – so I’ve just gotten into the habit of feeding from the bottom like Jamie did – this way the heat carrying water goes were he tells it to, not where Isaac Newton says it goes

heat trap

Shouldn't there be a check valve on the supply for the manifold anyway?

Kal Row

the head loss of a spring check

is greater than the head loss of a u loop and is yet another thing to fail, leak, or chatter - naah, jamie did it right!!!

Kal Row

jamie - question, on the new install...

did you use the new "clicks" clips, cause the way it was until now, it would have made expansion noises, i always worry about that in a staple-up-job

Jamie_6

We actually used Wirsbo Quick Trac plates on this install! It brought our supply water temp. down drastically and gave the homeowner some room to play with future floor coverings. Not to mention that with the clips our water temps where pretty close to there limits any way.

Hot Rod,

The tubings writing says ( entran 3 UPC 2774 ) on one side & ( 11 01 94 A ) on the other.

By the time this call made its way to us the tube was disconnected from the manifolds and valved from the boiler. From what I understand there was multiple locations where the tubes had failed.

I gave the HO this WEB address so maybe he will post and fill us in.

It is insane that any one has ever used rubber. especially that they are still installing it. Industries best and brightest?

swing

I'd use a swing check on the supply pipe directly after the pump for that zone. I dont think the fluid in the U-loop is sufficiently cooler than the fluid in the floor to prevent flow....especially if pressure from another zone is finding its way to that manifold.

Kal Row

smart move

another product of the same idea is Thermal Track from Zurn same idea "http://www.zurn.com/pages/catalog.asp?ProductGroupID=137&OperationID=17"

the Zurn has the alumanization on top – but never tested the two side by side

we don’t have magazines with independent test labs in this industry like they have for other things – glad god gave us dan and the "wall" or we be completely in the dark

my personal rules to radiant, are: on the ground level, to install it in concrete or gypsum slab, on above ground levels, on top of the floor base, however, bedroom levels, are best done in the ceiling with plates over the sheetrock beaming down, since in the bedrooms, people are on top of things, rather than with feet under tables and desks, as on other levels, in bathrooms of course it should be all around especially the shower

by using Quick Trac, you have built a very serviceable system, not to mention a system with a much lower resistance level, wonder if the customer appreciates what you have done – guess they will when they get their first reduced heating bill

Entran 3


never had a problem. Ever. Not covered in the litigation.

Entran 2 did, and only about 6% of it. I've seen the problem tubing, and there is no way anyone could mistake the fact that the MANUFACTURER screwed up.

You replaced tubing that had nothing wrong with it.

swing checks only stop

inter-zone differential pressures, for gravity ghost flow, however, only a spring check will guarantee gravity ghost flow checking, but, I’ve found – that pumping down 18 inches from hot to cold, to be a sufficient thermal trap for most applications, and while the loop is only 12” from the lower supply manifold, there is more then 18” from the supply pipe on top, so it should still trap, from the rest of the house,
but, if you still have a ghost problem, by all means, sprinkle the system with spring checks, ziggi always does, and I do too, if there is a domestic hot water holding tank is in the picture, or if the temps or heights, are radically different between loads
