Why do I keep seeing overflow pipes (or boiler condenser pipes, or whatever they are) on people's houses with the pipe curved round 180 degrees so it faces the wall? Why on earth would you want the water to run down the wall instead of fall a few inches from the house?

They are two separate things.
Which are you on about?

I have never seen this.

Condensate should be taken to a drain.
An overflow should be in a conspicuous postion so you see it if it
overflows.

(nicked from Caecilius' ongoing thread "What's this dripping pipe")

Any pipes configured like this are ones which are likely to spout very hot
water in the event of a problem with the equipment like a boiler; ie, they
aren't simply overflows from a cold water cistern. Therefore the intention
is that any such water (which could emerge at force) is deliberately
directed safely at a wall, rather than sprayed over or dripped on a passer
by.

They come from the boiler pressure release valve and are positioned like
that to prevent anyone near them being scalded if the valve opens.

Oh dear, typical argumentative comment.

You've had a perfectly accurate and rational answer given to your
question, why prolong the thread with further unnecessary whinging about
something that is a definite and serious risk that has been assessed and
reduced to almost nil by the simple procedure of putting a bend on the
pipe?

"slightly hurting someone" if you ever get boiling, or near boiling,
water poured onto you, from what ever source, just remember your comment
that it only slightly hurts.

No, a simple statement about the pathetic way we do things nowadays. 30 years ago, you'd have been called a pansy for even suggesting such a safety feature.

I have done. And it does only slightly hurt, because I'm not a little girl like you. We're not talking about a ****ing gallon of the stuff here, just a spray from a pipe, which you can move out of the way of.

I would think it better not to have your wall soaking wet.

I don't have such a thing so I don't care. I don't have a combi. I have a system boiler, and the overflow of the header tank is on the eaves, stuck out straight, as is traditional.

As against having someone scalded? These overflows are only in use when
there's a fault that will release scalding hot water under quite a high
pressure from them when the pressure relief valve opens, which isn't
exactly an everyday occurence. The wall will get wetter every time it rains.

Bear in mind that as the property owner or occupier, you are liable for

My combi was installed upstairs, the over pressure vent pipe was taken
through the wall where it exited the boiler, so it is about 8 inches to the
left of the front door, and about a foot higher than the top of the door,
As the door is on the side of the house people have to walk past the vent to
get to the door, up the drive with a 6 foot fence to their right and the
garage at the end,

i know i wouldnt like to be at the door if the boilers over pressure valve
opened and the vent pipe was pointing out so it sprayed over the drive,
my car is also usually parked on the drive so it would be in the line of
fire from an outwardly pointing pressure vent pipe, i wouldn't particularly
want it being doused with near boiling water with inhibiter and other crap
in it either,

i'll wait for creepy uncle peter to come back with something like his car is
built to withstand a spraying of boiler water, and the billion to one chance
of it happening whilst it's parked there.


There was a million to one chance of an immersion heater stat failing
closed, allowing the water to boil and exit the vent/expansion pipe that
loops over the plastic header tank in the loft,
was it a 2 million to one chance that in the bedroom below the header tank
was the baby in it's cot, asleep when the plastic tank ruptured due to the
water in it being brought upto boiling temps by the vent pipe discharging
it's boiling water into it for a few days?

I read about a lecturer taking a class and talking about probability.
The practical example went something along the lines of "would you take
a risk of 1 in a 1000?" Many answered "yes" so he produced a very
large jar of jelly beans and said that 1 had cyanide in it, then offered
them around the class, no one took one!

May or may not be true, but it does illustrate how peoples viewpoint
changes when it directly involves their own imminent death and
destruction.

Audi drivers excepted of course :-) they are immune to probability
and drive as though they are immortal, but that's a different thing all
together.

I recently had the header tank taken out, a relief since:

1) there are no longer pipes in the attic to freeze

My attic doesn't go that cold (as it's above the house) and the pipes are lagged.

2) there's no tank to accumulate grot and dead animals

No lid?!?

3) I get mains pressure water, much better

You only need that much pressure for a garden hose. Are you watering the garden with hot water?

No.

How often is a person at that exact point on your path? How often does it overflow? Multiply those two very small fractions together and you get an infinitesimal chance. They're more likely to trip over a loose paving stone and break their neck.

It's very unlikely, and a small amount of hot water won't hurt it. I do that several times a winter to melt the windscreen.

Oh here we go, babies are a million times more important than adults, that old crap.

you don't care much for million to one chances when you are that millionth

But chances are you aren't that person. You're one of those people who enter the lottery because you say someone has to win it. Chances are it will never ever be you.

I can assure you that the one at my parents first floor holiday

Trust you to find an exception.

My combi was installed upstairs, the over pressure vent pipe was taken
through the wall where it exited the boiler, so it is about 8 inches to
the left of the front door, and about a foot higher than the top of the
door,
As the door is on the side of the house people have to walk past the vent
to get to the door, up the drive with a 6 foot fence to their right and
the garage at the end,

i know i wouldnt like to be at the door if the boilers over pressure valve
opened and the vent pipe was pointing out so it sprayed over the drive,
my car is also usually parked on the drive so it would be in the line of
fire from an outwardly pointing pressure vent pipe, i wouldn't
particularly want it being doused with near boiling water with inhibiter
and other crap in it either,

i'll wait for creepy uncle peter to come back with something like his car
is built to withstand a spraying of boiler water, and the billion to one
chance of it happening whilst it's parked there.


There was a million to one chance of an immersion heater stat failing
closed, allowing the water to boil and exit the vent/expansion pipe that
loops over the plastic header tank in the loft,

I am not sure that it is a million to one chance. I have seen that happen 3
times.

But you're a plumber. You're exposed to the faults all day.

Worried it will damage the wall?

I would think it better not to have your wall soaking wet.

By soaking wet do you mean when it rains, you know the stuff well as
you
live in Scotland:-)

We do have eaves you know....


So do I but there is no protecton against rain hitting the gable end of
the
house (or the rest of the walls when it is raining and windy)

You have no eaves on the gable end?

or having the equivalent of a boiling kettle full of
water blasting out out of the pipe in about 1 seconds time should there
be a
problem with your boiler ?

You must have **** boilers if they do that. What was wrong with the
traditional header tank?

They only do that if there is a fault. There are lots of reasons why a
traditional header tank is not used on some installations.

If the fault is common, the boilers are ****. If the fault is uncommon,
why worry about it?

I don't have such a thing so I don't care. I don't have a combi. I
have
a system boiler, and the overflow of the header tank is on the eaves,
stuck out straight, as is traditional.

This is not purely a combi related feature. It's a feature of all
pressurised installs. If your system boiler was installed as in the
second
picture in the link
http://www.worcester-bosch.co.uk/hom...-system-boiler
then you would of course have the discharge pipe.

My mistake, I meant to write "condensor", not "combi".

It is indeed your mistake. Condensing boilers have nothing to do with
your
argument and are not relevant.

Condensors are the ones with the outside pipe to let out water.


Of course they are. I forgot about that snippet of information:-)

Actually combi was correct in the first place. Non-combis have header tanks, the overflow goes in there.

I would think it better not to have your wall soaking wet.

As against having someone scalded? These overflows are only in use when
there's a fault that will release scalding hot water under quite a high
pressure from them when the pressure relief valve opens, which isn't
exactly an everyday occurence. The wall will get wetter every time it
rains.

Bear in mind that as the property owner or occupier, you are liable for
any injury suffered as a result of ho****er escaping form these pipes
and scalding them.

Oh don't be ridiculous. Chances are it wouldn't start squirting precisely
as someone walks past. If it's already squirting, they would avoid it.

We are talking about a one second blast of hot water from the pipe - about a
kettle full of hot water - and then the PRV has done it's job and the water
stops coming from the pipe.

They only do that if there is a fault. There are lots of reasons why a
traditional header tank is not used on some installations.

I recently had the header tank taken out, a relief since:

1) there are no longer pipes in the attic to freeze

My attic doesn't go that cold (as it's above the house) and the pipes are
lagged.

I see, no attic insulation.

Yes, but it's not 100%, insulation never is, or you wouldn't need a boiler in the first place.

I wouldn't want my attic going below freezing, the paint I store up there would get damaged.

Lagged ha ha ha.

You've never heard of lagging?

2) there's no tank to accumulate grot and dead animals

No lid?!?

****ed if I knew, I didn't go up there did I.

It would be a bit odd to have one without a lid on it.

3) I get mains pressure water, much better

You only need that much pressure for a garden hose. Are you watering the
garden with hot water?

No, I'm catering for more than one person using water in the house at
once.

Gravity from the header tank in the attic is powerful enough to run two taps, just not at high enough pressure to spray a hose.

That do you?

No.

SOOL then, aren't you.

NO, it means I won the argument.

It is impossible for that quantity of water to come through that thin pipe in 1 second. The pressure would be enough to blast a hole in the brickwork.
