Seems to me

Your forgetting about vapor pressure, which means regardless of the refrigerant pressure in the pipe if the vapor pressure is lower in the pipe [which it should be if you just pulled a vacuum] then in the air surrounding the pipe you will introduce moisture back into the system. Basically the same way moisture gets into the supply side of a duct if you don't seal all the joints with tape or duct seal.

First off you

Need a new plumber. While a outdoor reset control may be a good idea, it most definitely won't solve your problem of the system running continuously

Like Steam

Says, anything is possible, but how big a check do you want too write?

A valve core?

You should not

@ April 20, 2013 12:03 PM in Direct Pump TT Solo 110 with 3 zones

Direct pump that boiler with that piping design. You must primary secondary.

Sounds like

A bad TEV not letting refrig through and causing refig to back up into condenser.

The correct time

@ April 14, 2013 10:50 PM in vacuum

To evacuate a system is after all the holes are filled and there are no more leaks. Rim shot boom. Take my wife, please take my wife. Or as Tech says after all the mositure is gone or in his case the flood has subsided.

never let that

@ April 11, 2013 7:51 AM in Never Cleaned Munchkin 80M

service tech in your house again. Like the others said it takes less then 15 mins to actually look at the HX. And maybe and hour to clean. I have open up Munchkins after many many years only to find a nice claen HX.

I'm gonna take

@ April 9, 2013 8:10 AM in Indirect installation on Alpine with MCBA control

And my brains not fully awake yet but as far as questions 1 & 2 go I would use the piping off the manual that came with your boiler and not the "new manual". Question 3, you want only one pump running so your recovery time on the indirect is as short as possible.

If there is

@ April 7, 2013 1:29 PM in radiator use as A/C?

No condensation then there is really no cooling.If you can't lower the dew point whats the point? On the other hand if you take a beer out of the frig and set it on the table and you get no condensate on it you shouldnt need the cooling.

Is this the set screw

@ April 7, 2013 1:18 PM in rheem warm air furnace

Adjustment that has a 2mm set screw inside a 3mm set screw? If it is you need to replace the valve and If you ever find the guy that dreamed that up, kick him in the butt.

A little more

@ April 7, 2013 1:10 PM in warminMaine

Info please. What did you clean. Did you open the oil filter. Did you remove the nozzel?

If you have a volt meter

@ April 5, 2013 10:26 PM in Thermostat C wire to "COM" on Taco SR502?

Check between that "com" and the "T" terminals. If you get 24v you should be ok. But for some reason I don't think that top left terminal strip is and output.

@ April 5, 2013 8:59 AM in Pumping Awa Question

I use those evil on off tstats and they stay within a 2* diff. Thats fine for me. Also when it's broke it dosent take hours and hours to trouble shoot and cost a thigh and a shoulder to fix. I have found even the most simple energy saving devices don't save enough over their lives to pay for the replacement costs. 

It's to old to worry about

@ April 5, 2013 8:39 AM in Stupid question here but can't seem to figure this out.

First of all it’s a 40 + year old boiler is any time spent repairing and not replacing is a waste. But if the customer insists then I would first make sure he’s gonna pay regardless of results. Then I would start by disconnecting aqua stat and cooling down boiler and starting top floor zone only. Let boiler fire up to maybe 160* and see what happens in the other 2 zones. If other zones are fine most likely aqua stat if not you might be able to check by feel whats up with the other zones.

I belive the ole

What goes into a tee must come out rule applies here. So 3.

@ April 4, 2013 8:42 AM in Digital thermostat on an incremetal PTAC (type K) with electromechanical contorl box

Who/s gonna push the buttons and where are you gonna cram all the relays needed? You have to order the PTAC's for wall mount tstats if thats what you want to use. Sounds cheep to me for the whole new controller board. Any other way is a can of worms.

Most likely

@ April 1, 2013 4:30 PM in Munchkin burner making steady loud noise

A bad blower. If you can't find a power switch at the boiler it will soon enough lock up and stop.

Techman my point

@ April 1, 2013 4:25 PM in Window AC water slinger vs dry question

Being is that it's not measurable due to the fact that there are times when the water is in the pan and times when there is not. Same with that A/C unit. I used to always fill those drain pans up after replacing a 9watt cond motor to get the box to pull down.  I love arguing hypotheticals.

@ April 1, 2013 4:11 PM in Need Help With Honeywell Relay

Like the relay in Pauls first post go to a local supply house and ask for a 90-340 relay or just bring the old one in. Make sure you have the retaining wire that keeps the relay in place.
