Central Boiler / Re: Thermostatic valve questions.

Well I think its time to dissect the valve and see what's going on. My luck I will find Jimmy Hoffa in there. Since we didn't find Indian bones doing the Thermopex I guess its about time for something to go wrong. LOL

Central Boiler / Re: Thermostatic valve questions.

No Im not forcing a bypass. Im just trying to figure out if I have good flow AFTER the thermostatic valve. Any water valve on the planet makes noise, if the pressure behind it is great enough, when you open or close it. I have a shut off valve before the Thermostatic valve and I have one after it. When the boiler loop is at temperature and running. The amount of cavitation noise at the shut off valve BEFORE the Thermostatic valve is much greater than the valve AFTER the thermostatic. Since the noise level goes down seems to me the flow rate did too. Im just trying to figure out if this is normal.

Central Boiler / Need to replace the float valve
« on: February 05, 2021, 11:06:58 AM »
So in CB's infinite wisdom, I understand that they use a SIDE mounted float that requires draining to below that level. Vertical floats had been around since the invention of the gas tank. 
I have IBC's to drain the tank but anyone have a suggestion for a pump to return the water when done? The Little Giant Pony series looks great but its only rated to 140 degrees. Any one use on for this purpose? Or any other suggestions?

Central Boiler / Thermostatic valve questions.
« on: February 05, 2021, 10:16:04 AM »
Im a NOOB when it comes to the whole OWB thing. Its a new install and I have never done this before. Something is not right just not sure what since I have zero reference and zero experience. This system has been up and running for a week or so and needs to be ironed out.
I have shut offs (both lines) as soon as the Thermopex enters the building and before the thermostatic valve. If I close down either of those valves you can hear cavitation and obvious flow to and from the boiler. The thermo valve is 4ft from these valves. Then 50ft more is a second set of valves at my floor loop. If I shut off either of those valves there is no cavitation sound. Is that just "how it is" or do I have a loop issue?
We have heat all thru the loop but IMO (remember Ive never done this before) after the valve the flow seems to have suffered.
