Next door has had same 'vent pipe' problem. Drain was running slightly uphill on a Horizontal run before going through outside wall,build of watter at the elbow had frozen. Apparently inhibits correct operation of boiler.
Engineer was right P1553d off,he's had to do dozens in one week.

THERE NOT ENGINEERS 

what do you consider to be an engineer then Mark?

PS Mine is internal

Slight deviation of thread  but I've just tried to use my 'outside' tap which is on the house side of my attached garage ........ it's frozen!  :-? :-? My point being is that it's not going to easy to stop a condensate drain from freezing if it goes anywhere near outside.

Its simple Andy.

They specifiy a large bore pipe with a set fall and a maximum length as that will ensures that the water runs and cant freeze.

The water will exit the boiler at a 'reasonable' temp, it takes time for the condensate to lower in temp to the point it will freeze, hence the max length and fall specs

The insulation is there to give a safe guard.

The water in your outside tap freezes because it sits there slowly getting colder and colder.....

My neighbour's drain pipe is 32mm, about 3' long, and froze solid. See my link above.

If it's that cold even hot water will have frozen by the time it gets to the end of a 3' pipe.

If I was a cynical type, which I flecking well am, I'd say it's deliberate to get the recall work.

Surely it's easier to fit a straight drop than a u bend or whatever...?

Why invest time making work for yourself.... I wonder? (assuming I've understood all this correctly of course)

Clearly in this cold weather, more thought is required to stop condensate pipes freezing. My neighbours 32mm external has frozen, and he hopes to solve it with boxed lagging. With continual temps below freezing, it will still freeze. I have sent him this link.

PS Mine is internal

But does it have the correct fall on it.

TB Asked me to post these - This is a British Gas install at a colleagues house

what do you consider to be an engineer then Mark? 

Engineer

1. One who is trained or professionally engaged in a branch of engineering. (which plumbing, wiring and fixing washing machines is not)
2. One who operates an engine. (obviously)
3. One who skillfully or shrewdly manages an enterprise.

Technician

1. a person skilled in mechanical or industrial techniques or in a particular technical field (e.g. a plumber, sparky or reapir man)
2. a person employed in a laboratory, technical college, or scientific establishment to do practical work
3. a person having specific artistic or mechanical skill, esp if lacking original flair or genius

Unsurprisingly, it did.

As can be seen from the photos Jimbob posted for me earlier, the idiots haven't put any fall on the pipe, its frozen at the elbow, then overflowed into the loft space (fortunately, most of the water ran outside the house. The photos do not do it justice, the vertical part of the pipe is frozen solid, as is all the water that overflowed at the top.

Its amazing the number of bodge jobs I've seen recently...

Latest on: I've just started a new job which involves working with LCD projectors / PA systems etc for conferences. One of which is in a largish event room which can hold hundreds of people... and the main join on the feed to the projector (5 coax cables) is 3 BNC to BNC (fine), the other two just bare wires twisted together thrown under the desk. Not even taped up with insulation tape!

The increase in bodging is because we pander to the knuckle draggers, rather than let the army use them for target practice.


We have a retarded lazy prat at work - mgmt never blame him, but when HE cocks up (not often, he does sod all most of the time), WE ALL get a bollocking. When the rest of us make a mistake, we get individual bollockings...
