between sections leak why?

David Van Wickler_3

Be careful of the V8 series. Been hearing of lots of V8 leakers. Mostly steam, but FHW are doing it too after just a handful of years. Darn things rot out.

Just found this bioler leaking

Why do biolers leak between the sections? I know you can't tell untill you take it apart but I can't untill they warrenty it but I was just wondering what the bigest reasons are for them to leak like this. Is it a bad seal? Cold water return? too much delta T in the boiler? Not enough flow? If I had to guess it would be a bad seal at the factory. The unit is a 2003 and I have seen leaks with this boiler co. before. Any Ideas?

Looks like a Weil Mclain Model 78.. Am I right?

Alot of things can cause leaks between sections. Usually with O-Rings it is because of of an improper rope seal or not using silicone around the ring when burning oil. Pitting from poor steam quality can also cause leaks.Looks to me like you have a problem with chemical concentrations though.

Actually , it looks like

a Burnham V8 . We've installed hundreds of them so far since around 2002 , and not one leaker yet . It does seem weird that the only place the boiler is leaking is at the push nipples . Any of the reasons you stated could be the cause . What type of heat do they have in the house ? Is there a bypass on the boiler ? Do you have any pics of the piping ?

I haven't seen one yet, but the reports are that they are starting to show up frequently. I hope its an installation issue and not a production one.

The boiler in the pix shown is not a Weil Mclain nor a steamer as pipe coming out is way tooo small.. Looks like to me, water ph level is out of whack.

Is the system filled with Anti-Freeze? I have had experience with anti-freeze wanting out of the system any way possible, perhaps due to over pumping or over concentration. Others know more about it than I....

leak

I held off saying the name of the boiler cause I wanted an impartial look at the leaks. Yes it is a new burnham V8 and it is forced circ..........The house has maybe ten small cast iron rads on a direct return system. No bypass, I wish it had one..........I beleve the boiler is oversized for the house but we didn't install this one. I have to assume that this was not sealed right at the factory because of the speed that it leaked. I assume it leaked one to two years after the install and with such a small load on the boiler how could it shock the boiler that much? The way it was put together it is the most logical answer to this problem. The boiler should have a bypass installed but I can not believe that caused this problem and the ph level would have to be off alot if that was a problem. I have city water at the job so if the ph is bad I should cheak the boiler next door. thanks P.S. no antifreeze sorry about the sideways pic.

They had some\"bad\" nipples made by ....................

others awhile back. Now being made in-house,time will tell!

That isn't a \" small load \"

I'll bet there's more water content in the 2 inch piping and the rads than in the boiler . Combine that with no bypass and constant low return temps and this is what can happen . No traditional pin type boiler can handle that low return temp constantly , even after only a few years .

Can you tell us what model number aquastat that is ? Is it a cold start aquastat ?
