when you put the heating on the heat expands the copper pipe leading into your radiator, if the nut on the copper pipe attached to the radiator valve is not wound up tightly enough the expansion will cause the valve to leak slightly, it may look like the pipe is leaking but its the rad valve that needs tighening, get an adjustable spanner or wrench and tighten the nut anti clockwise about l/4" job done.all you people talking about bleeding a rad, why answer a question that you know less than nothing about, are you just trying to mess people up.

Most new installations are what are called "mini bore" hence the little pipe. If water is slowly trickling down the pipe one assumes that it is from under the valve. If so then the connection of the pipe to the valve may be slightly loose. This needs to be tightened. If it is a new house, you are probable within the 12 month maintenance period. Complain to the developers or builders and get them to send someone along to rectify the problem. Otherwise call in a qualified plumber or heating engineer. You may have to pay their minimum call out charge as this work should only take ten minutes at the most. Meanwhile, wrap an old towel around the pipe to prevent the water dripping on to your carpet and causing stains.

Depends what you mean by "the little pipe" .If its at the top of your radiator with the small square head ,it is the air bleed valve and just needs nipping up tight with a "bleed key" You should have one left by your installer..The fact that you say your house is newly built and the stain appears brown ,could be the water is darkened by a rust inhibitor that has been added to your water supply to prevent rust and scale build up in your system.Nothing has to be loose by the way..a tight looking joint may leak past the sealing ring on the pipe.Usually an eighth or quarter turn with the correct size spanner where the feed pipe enters or exits the radiator will stop the offending leak.Hope this helps..

Switching on the heat doesn't really increase the pressure. What I am saying is that if you have a leak, it should leak whether the heat is on or off. The simplest way to fix this is to try to tighten the fittings where the supply pipe enters the radiator.
If it still leaks, you may need to drain the system, open up the fitting, apply new PTFE tape to the threads and reconnect everything.
The brown stain is just rust in the pipes. You should put some additive in the system that prevents corrosion of the pipes. Eventually the water will be black.

The heating system works by hot water being pumped through the radiators. Sometimes you can get air locks within the system and the 'valve' at the top of each radiator allows you to release any air trapped in individual radiators. The valve needs tightening with a rad key. If there is no air trapped then the water will start to escape. You need a rad key, available from any hardware store or building merchants, or a neibour.

If there is a brown stain showing then the installer DID'NT add an inhibitor to the water, cost about £15, this prevents internal rusting.
In answer to your question , there could be misalignment in the nut at the radiator, Get someone to expose the olive, wrap PTFE tape around it and re-tighten. Unless you are familiar with this get it done by the installer, you are still under guarantee.
Get him to add FERNOX to the system when he is at it.

Which little pipe? Is it the inlet/outlet or the little valve where you bleed off air? If the first then it probably just needs a little extra tightening with a spanner. If its the bleed valve it also just needs a little tightening with a special square key - which you should have left with you if its a new build or you can buy one very cheaply (pence) at your local DIY store - just ask for a radiator key.

at the top of your radiator there is a valve in a round projection you need to get an alan key let the trapped air or excess water out by loosening this(handy to have a towel the water may spit and be boiling) do the same with every other radiator and you r fine.plummers term is bleeding the radiators.

because it has a leak, a joint or crack where air and or fluid can pass outside of a closed system. Duh. Call your builder if the house is new they should come and fix it.
Why does everyone think bleeding the radiator is the answer. IF ITS LEAKING IT IS BLEEDING ALREADY. Wing nuts!
Is it leaking from a join or the wall, did you feel it, is the pipe cracked? We can only give advise with all the details. But it sounds like a leak in the join and may need to be fixed by a plumber, or at least by someone who doesn't have to ask about it on answers.

You have started the heat system for the first time this season, and the water is expanding- are you sure its a little pipe or a Bleeder port.
