How Do I Add Water To My Boiler System?

Well, by golly--I hadn't noticed---that is one old system---still not the likely cause,

Another possibility is a nonworking pump--I've pulled out pumps and found the impellers completely gone---no water movement---no bleeding the lines---

If no water is coming out (and they are open) then I'd attach a psi guage( they are cheap) to your boiler drain to see if your tridicater is working.
In other words do you really have 10 PSI.
Yes, that's right. On the too cold radiators, when I open the bleed valve, you can immediately hear some air coming out but then it stops and that's it -- no water comes out. I even left the valve completely open for a day and no change. Hmm ... psi gauge ... boiler drain ... tridicater. I have no clue so I'll look these up. Is it easy to attach the psi gauge to the boiler drain?

yes it is easy.... you seem confused..... might be time to call someone..... boilers are not the easiest things in the trade..... be safe....

You need to post pictures of the piping system and the valves----there is a good chance that you have more than one zone and isolating the working zone will allow you to flush out the air---need more info.

We have several boiler experts here---someone will help if you provide accurate info---
There aren't any other valves on the water pipes in the boiler room and there aren't any other visible valves in the house. I suppose it's possible there are valves behind the finished walls but I don't think so. The house is only about 1500 sq ft (not incl basement).

The additional piping that doesn't show up in the photos is the piping that runs up from the pump (the taped/insulated pipe) and that simply branches three ways exiting the boiler room ceiling. On the opposite side of the boiler is another pipe entering the boiler which also comes from three branches exiting/entering the boiler room.

The pipe on the right of the insulated pipe runs up from the metal box to the expansion tank (which is empty).

Haha, yeah I did call someone (the furnace/boiler company that gave maintenance to it for the prior owners) but when the guy saw it, he said that he didn't want to touch it because it might break. But for $90 he told me I don't have any problems with CO readings and he also told me I can pull that release valve to add more water to the system, which turns out to be wrong. But I guess it's time to call someone else.

equipment that looks like it's about to break is my bread and butter. Too bad you don't live near me.

Ah Ok -- I see the boiler drain under the pump. Okay, I'll see about picking up a psi gauge and testing the actual pressure.

Additional possibly relevant info: My pump is emitting a clicking/rattling sound. A building inspector said that it meant "the bearings were going on it".

still doesn't explain why nothing is coming out of the bleeders.

How Do I Add Water To My Boiler System?


First off it is possible that the valve is blocked shut. I would replace it with a quarter turn ball valve, those gate valves are notorious for failing.

Second, either the pressure relief valve of the checkflow valve (the one with the arrow on it) could be completely clogged. I know mine were, and I have a similar boiler setup. I replaced the gate valve, check valve, and pressure relief valve on my system for about $60 worth of parts, and the makeup water now flows automatically.

As for bleeding the coin valves in the radiators, you can purchase automatic air bleed coin valves for a few dollars each, they should keep the air bled out automatically. Manual valves bleed best when the pump is running, since the air is moved through the system. I can never get a 100 percent bleed on my manual valves unless the pump is on. Your pump may be inoperable, you should check it by listening to it when the thermostat calls for heat. A loud ticking sound may be bad bearings, or silence may indicate a failed electrical system or a broken impeller.

How Do I Add Water To My Boiler System?


Temporarily ...Attach garden hose to boiler drain and to water supply ..you may need adapter to reconfigure hose to fit......open water supply then open drain slowly to back feed and pressurize system until water bleeds from upper rads. This should get you going temporarily until you can replace defective valve(s). OR install two Tees and bypass valve around feedwater regulator so, you can bypass water into system..need a valve and ability to sloder new fittings..then you can manually feed water into system..BTW ...your press gauge is the TRIDICATOR and they are usually nery reliable and not likely defective.

NOTE...DO NOT LEAVE HOSE ATTACHED TO DRAIN....IT WILL EXPAND AND BURST IF LEFT EXPOSED TO THE HEAT

Thanks techpappy -- this looks like a great temporary solution and also something I can do. I'll likely go with the hose suggestion since it's simpler but I am curious: I could bypass and solder in a valve and shut off the main water supply to do this, but how would I prevent water from flowing out of the system? I don't see another shutoff valve and I don't imagine you meant to drain it. Also, I guess there would be some risk from having permanently bypassed the pressure relief.
