boiler blow off

[buckley plumb]

been called to a boiler today as british gas did an ID on it as it was on a contract and been passed by them each year till now .It was an older boiler i have never heard of its about 6years old - its in a terrace between the kitchen and bathroom and has no external walls , the condense goes into a drain connector 40mm to 4" in the floor in 40mm pushfit pipe and due to the bathroom having a floor fitted 3" showertray they put the blow off into the 40mm pushfit pipe with the condense. it has been Id due to this - my question is that G3 allows for an unvented cylinder to be into a drain via push fit so why not a combi blow off ? also i have seen a condense pump that accepts a blow off as well so if a conense pump can why not a waste .

Does it need a tundish?

 

[buckley plumb]

thats what i was going to do but they said its got to be on external wall - think they just want out of contract as boiler is old.

i was always told that a PRV discharge pipework must be outside regardless no matter what!, so i've always gone with it and have changed them if come across it, i think i know where your coming from i'd like to know the reason to, Kirkkk??? help here please lol.

I wouldn't think that would be ID, maybe its cos the plastic pipe might not be able to take the temp of the water but doubt it.

bg are hungry again ,as winter is running late

Well frosty here tonight and the roads are slippy!

seen plenty of blow offs into internal waste systems via a tundish. Done in flats all over the place. Its def not ID.

My advise, take BG's customer for yourself and save them money.

so its about to start then I take it

Went to repair a storage combi, which has two blow offs. They just discharged to the floor, below. Well onto the electrical outlets and then onto the floor below.

Didn't think it was an ID offense. I didn't bother looking it up as I just put it right.

 

[Mbear]

Defo not ID, I'd say AR at most due to discharge material being plastic.

But not ID, no chance

 

[tamz]

At risk of what? Nothing to do with gas but we all know big gas make up the rules to suit themselves and definately not ID. Just down to some over zealous gas man who hasn't a clue.
Even if it was capped off it is only AR.
Better write myself out a notice while i remember :shame:

you can run a discharge pipe into plastic waste, normally needs to be pushfit.

 

[Dannypipe]

Now if you capped off the blow off. Then in my opinion you'd be playing with fire.

Never come across it, but it must happen.

"Oh that overflow pipe is dribbling. I'll nip to B&Q and buy one of those speed fit caps, that'll do it". :nonod:

Pressure Discharge pipes should be metallic as far as i can remember, especially unvented hw/d2.

Blanking a safety pipe is ID in my estimation, no questions .
I've seen it once b4, handyman wasn't so handy

 

[Dannypipe]

Yes an ID, but in fairness the first thing you'd do is unblank it. So hardly worth filling out the paper work.

You've seen it? I know it must happen. A little knowledge in the wrong hands is dangerous. I wonder if it was the handy man, or actually the man of the house who was just too embarrased to admit to doing somthing so stupid!?

 

[tamz]

I wonder how BG would class an Atag where the blow off is connected to the (plastic) condensate pipe?

 

[Dannypipe]

Ha. God knows.

BG do have some top class engineers, but like any organisation of that size, they're going to have a few numpties too.

the g3 regs say plastic can be used if it can take the temp, most push fit can but not solvent weld. Combis dont really come under g3 unless they have a storeage vessel 15ltrs and above.

Customers lie all the time so who knows, i cut away the nut aswell so noone else had a bright idea to stop the 'leak' if it ever happened again.

I know that Danny. Unfortunately most of the best ones are getting old or fed up playing their games and have left.

This may be true but unless u install it and know what it is how can u satisfy yourself as to what material it is unless it's clearly marked which (in my experience) it rarely is. Copper is the safest option by far
