Re: How to prevent hydronic piping from freezing?
Not when the person asking the question specifically said it was about pipes not freezing.

That's what I'd use, then — much less hassle than orifices…
Re: Good or bad? Tubing
Water can diffuse through gore-tex as a gas but will not allow liquid water to pass even though it's the same molecule. Good example of how bulk properties of a compound are more important than the absolute size of the individual molecules when it comes to diffusion.

Re: Carlin 41000 ignitor premature failure solution
That setup may work fine, however it may void warranty and any safety feature built into the OEM design. That may void said safety feature and may be a reason for denying an insurance claim if something catastrophic may happen (like burning your house down) regarding oil burner operation.
I would replace the existing Primary Safety control with this one to get the feature you want
Also, operating your burner without the ignition on during the burn cycle may cause the flame to perform differently. You should get a combustion analyzer and make sure the burner is set up properly. Since the combustion analyzers are expensive, you may just bite the bullet and get a Pro to use their analyzer for you.
Re: Flame Retention Head for Weil Mclane Boiler
That burner was manufactured FOR Weil McLain by Wayne.
The head should be attached to the nozzle assembly. If it's not there, then it burned or broke off and is lying in the chamber. And if that's the case, then there's bigger problems than just replacing the head.
That burner has had Gremlins since it's inception, and it's gone for a reason. Consider an upgrade to a Riello 40 Series, or a Beckett AFG.
And find the cause.

Re: Flame Retention Head for Weil Mclane Boiler
Maybe the old one burned off the burner tube. I am not familiar with the old QB (which was made by Weil McLain) but if I am not mistaken it was a short-lived burner that was not very good.
You might want to rethink replacing the burner with a Carlin or Beckett burner if the boiler is in good shape. Not sure if the part he needs is even available.
Re: Good or bad? Tubing
That's not entirely true.
Some ice can be denser than water.
However, I am curious what some experts would say in regards to O2 being able to get through a material where water does not. Especially if the water is under slight pressure. All of this is way above my paygrade.

Re: Lochinvar Knight Boiler Flame Fail Ignition Errors - ready to pull my hair out
Did you look at the board? A relay like that is rated for millions of operations, even like 10 cycles an hour is nothing for that type of relay. Usually problems with relays in that application are that the solder fatigues and cracks where it is soldered to the board.

Re: Correcting my 2 Zone Monoloop System (Need Help)
@LRCCBJ Said: I would not spend the time to put the circulators on the supply side. It's a day's work and it is not going to improve your situation a significant amount.
I disagree with not improving the system. I had a customer with a Monoflo® system. We were always having problems with air bound radiators because the auto vents on each radiator were not working. So I would need to show up twice a season to help the homeowner with the air bleeding process and drain the expansion tank. When it was time for a replacement boiler, I located the circulator pumps on the supply side after the PONPC that was also on the supply side of the boiler……. Never had an air problem after that!
So if @JWieg727 is going to change the near boiler piping anyway, then why not create the best air removal location in the system. The hottest water at the lowest pressure. With the circ pumps on the return, that place does not exist. With the circ pumps on the supply and the PONPC just before it on the supply, you have the best air removal system built into the design of the piping.
Re: Correcting my 2 Zone Monoloop System (Need Help)
There were some old style ball valves that had a screwdriver slot to open/close them. You can use ball valves for balancing, you just have to understand the correlation to the handle position is very much not linear. You can't use gate valves for balancing, they must be fully open or closed or the gate will vibrate in the flow and destroy the threads on the stem.
If the circulators are always both running at the same time then you don't need the flow checks(not sure why they did that, the reason to have 2 circulators would be to be able to zone the system). You do need to balance the 2 loops so that it will heat evenly(or change the control so it does run each loop off a separate thermostat).
You could add another loop for the problem loop or the regular tees and balancing valve would probably be ok even though it would decrease the overall flow some.
See how the tube end of this npt to crimp adapter is much smaller than the npt end, this type of fitting will restrict the flow too if this is the type of fitting you are using:
