Anybody familar with Gas Boilers?

[homersipes]

maybe low-water cut out is bad??

[Nefarious]

Where did you vent the air at? At the high point for each zone? 

Wouldn't be the first time a pump went out, or debris moved into the pump and caused a jambed impeller. You may need to call a heating specialist.

On the far end of the house there is a faucet, i also drained a little more off the faucet on the boiler.

I haven't played much with water systems either, mostly steam.  It sounds like you are going out on a high temp safety.  I bet your pump is shot.

A running pump doesn't make it a working pump.  The gravel sound could be broken impeller blades grinding themselves into sand.

Well it doesnt sound restricted, or metallic. Sounds sort of like water with air in it... were calling a tech today... lame... id hate to screw with it more than I already have and break it more.

That little red pump doesn't have a replaceable coupling--it's direct drive. It shouldn't make much noise to speak of when it's running. You either have some sort of debris stuck in it or you're hearing the remnants of the impeller rattling around. When we have problems with them it's a throwaway. Usually a heating supply house item.

Bingo. Tech is on scene and getting estimate now.

We were quoted $500 for part and labor to replace pump.

I just found the pump online Bell and Gossett NRF-22 for $100. They quoted us $320 for the pump and $150 for the labor!, Am I missing something here?

Do I need parts like gaskets and stuff that aren't included in the websites online?

[kappa]

that would be easy to replace.. valve it out, drain the heat exchanger, unbolt/rebolt, valve in..

edit: and kill the breaker first.. hehe

ahh im a retard.. you rattled me with 'direct drive'.. had to google it..   impeller bolted on the rotor.. I'd not thought of that but seems pretty common in this application..

Yeah for smaller systems like this they're fine. The only thing I hate about them is they're totally sealed with no visible parts which make them hard to easily troubleshoot. They run so smoothly it's sometimes hard to tell if it's running or not!  The larger models of this type have a cooling fan you can see on the motor at least.

Nef, if you're fairly handy you should be able to do this. Talking two pairs of nuts and bolts. A pair of gaskets. Kill power to boiler. Drain system or isolate the pump if you can. Disco the electric at the box on the pump. It's 110 so you only have hot neutral and ground. Hard to screw up. Unbolt. Clean flanges with a green scrubby pad. Put new gaskets on pump. Self explanatory when you see it. Slide new pump in. Bolt it up. Reverse the rest. Fill and bleed system.

Yeah, I'm not that handy. I might have a friend or two that I can hand wrenches and beer too though. 

Do I need the one with flanges or no flanges? I don't know.

It looks like yours has flanges from the picture.  There should be a gasket between the pump flange and the pipe flange (this allows the pump to seal to the piping).  Once you disconnect the pump, look to see if there is a gasket on the flange.
