Frozen pipes
Quick summary,
The water pipes to the house appear to be frozen before the stop tap and more than likely somwhere under ground (either beneath the floor boards or
under the drive)
Severn Trent waters, answer via their website is to wait until the pipes thaw (likely to be the weekend at the earliest)
Anyone got any suggestions on any other methods to speed things up a little?
Please bear in mind i have no access what so ever to the alledged frozen pipework.

You can't get to them, but how close can you get? Heat up the floor where they are under? Make that room really toasty?

various bonfires? unless you have access to the pipes, can't really think of anything you can try...

Sounds a sod, can you remove just a second of floor, prehaps under a bathroom unit, and get a 2k fan heater in there?

is it just your house not whole street? i would think unlikely to be frozen in the ground, more likely to be if within void under floor (do toy have
suspended floors?) or within water meter chamber, i would look here first if possible, i have stuck a pipe onto meter chamber from car exhaust and ran
it to warm it before

It's a bit annoying really, because the boiler is in the garage complete with a 5 degree frost stat, the heating for the house will not go off
once the garage temp hits 5 degree (that's ok)
Beacuse of this we never really have to worry about the pipe freezing in the home but............ the stop tap is located in the cloakroom which has
dimensions of approx 3'x5' one of the 3' foot walls and both the 5' wall are externals, and with 4 air bricks in those walls
you can imagine how cold it can get under the floor. Now because the stop tap is located in this room (which is always warm) but the floor underneath
is at this moment in time -10 or more (it's been -16 at night for the past week now) I'm guessing that it's the pipe directly
beneath the floor which is frozen.
I really don't fancy having to rip out the toilet, vanity unit, sink, tiled floor, skirtings, floor boards etc just in case the problem lies
elsewhere (closer to the water meter near the road) especially when it was only fitted out last year
having said all that, if it's burst then i will have too anyway.
dhutch touched on the subject i was hoping for, is it possible to wire it up to the national grid and heat it up that way? Think i'd rather get
someone in to do it if it can be done.

Yeah just our house, having spoken to the neighbours, i've been informed that the houses about 50 yerds away had the same problem yesterday and
Severn Trent Water popped out and sorted it, unfortunate for me, today they will not answer their phones 
Hmmmm Piping warm air in to the water meter area sounds worth a try

Caant you get some sort of heater outside and blow the warm air through the air bricks in to the void under the cloakroom....
surely this would thaw the pipework....

If the pipes have frozen isn't there a good chance they've split? So if it is under the floor boards, pipe warm air in and then
you'll have mains presure water spraying under the floor with no way to turn it off... or am Imissing something?

There should be a mains stop valve on the boundry of the property too, so if when it thaws there's a leak, then it will be no water until the
repair has been done
Tried all sorts to warm the pipes up, but after an hour sat ourside with a heat gun blowing hot air in to the air bricks there was still no joy, to be
honest i'm not so sure the air was getting to where i wanted it too, or at least not with enough flow to achieve anything, It's a huge
expanse under the floor so i'd guess a hot air gun would take longer than just waiting until the weekend for the temps to pick up.
Thanks for the suggestions, but it looks like i'm going to have to sit it out
Just melting a bucket of snow for toilet water at the minute

Chris,
sound like you need to head the void up if the ground under the air bricks/bathroom is soil or building ruble i would be boiling pans of snow on the
cooker and pouring the hot water down a pipe pushed through the air bricks into the void closest to the pipe, even if the water soaks into the gound
it is likley to increase ambient temperature ( ps seal the other air bricks to retain the heat).
must be worth a try

Chris,
Is the incoming pipework to the stop cock plastic of metal? In my experience they're often plastic.
If it's metal you might try heating the pipe from the stop cock using the heat gun. Applying the heat directly to the pipe might at least allow
the heat to draw along the pipe and thaw it. I guess even dribbling boiling water onto the pipe might work if not a bit messy.
Also (from past experience) when you say there "should be a mains stop valve at the boundary" do you know where it is and that it works?
My BIL suffered a lot of water damage a couple of years back with a frozen and burst pipe before the house stop cock. He knew where the mains stop
was and had no trouble getting the manhole cover up, but the stop valve was foobarred and wouldn't close!

Thanks for the reply guys,
So far i've tried everything available to me or what's listed above.
Heating the pipe with the heat gun, warmed the pipe up nicely about 12" from the point it disappears under the floor, so assuming it worked the
same in both ways then it was warmed nicely 12" under the floor and no doubt a bit longer than that too. No joy though
Seeing as the temps outside haven't got above -10 all day i've had the air bricks covered over, while this won't do a great deal
i'm hoping that the radiator pipes that run approx 2' away from the water pipe will generate enough heat to help the thaw.
Other than that i'm going to sit it out and keep having an hour here and there warming the pipe.
Fingers crossed i have some running water by the morning.

Just a thought Chris...any plumbing work needs doing in the rest of the house? Great time to replace that dripping tap or fit that isolation valve
you've been putting off for ages

Finally got through to Severn Trent Water, they claim when the estate was built (15 years ago) the water pipes were not sunk deep enough in too the
ground and as a result they are now freezing, oh and it's our problem not theirs
So just wait for the thaw and see if i can claim a new Spa, bottle and sell the water, Renishaw water coming to a supermarket near you soon.

so they think its frozen under the garden? I was going to suggest leaving an iron sat on it. (the internal pipe, that is)
Think you're going to have to start digging anyway

i have had the same problem at my house. the stop cock on my house is at front of property and sun doesnt get round there in winter to warm ground up.
i purchased a metal bucket, placed lots of holes around and made a small fire in there. doesnt need to be big.placed the bucket roughly in line where
pipe is and cleared the frozen pipe in 15 mins. people look at you strange though as they walk past. must think i am trying to set house on fire!!!

1.10am the water come back through the pipes, no signs of any leaks outside or under the house as far as i can see, just a case of waiting and
seeing.
Seems strange how Severn Trent water said there wasn't a problem with the supply and it was just our frozen pipes, yet they managed to thaw
while tempretures are below -10 in the early hours of the morning.
Still it's back on now

Leave a tap trickling inside the house to keep a flow of water through the pipe and it might not freeze again. Unless you are on a meter
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.
