<p><b>New page</b></p><div>This article is about fitting [[Thermostatic Radiator Valves]] to [[microbore]] pipe used in [[Central Heating]] systems. It is equally applicable to fitting manual valves and lockshield valves when reworking or extending an existing microbore system.<br />
<br />
The approach described here uses a standard 15mm valve and a soldered 15mm*8mm or 15mm*10mm fitting reducer (e.g. [http://www.bes.ltd.uk BES] 6786 or 6787) to connect to the microbore. This avoids the difficulties that are likely to occur trying to fit a new 8mm or 10mm valve to existing pipework: because microbore copper is very soft the pipe is often found to be distorted when the old valve's olive is removed making it very difficult to get a good seal to the new valve. Even if the pipe is not distorted it is very easy to over-tighten microbore compression joints resulting in leaks. Because this method uses soldered joints the heating system must be drained down to below the level of the valves being replaced.<br />
<br />
'''TIP:''' If planning to replace several valves on an existing system check the diameter of pipe on '''''all''''' valves to be changed: often systems have a mixture of 8mm and 10mm pipework.<br />
<br />
{| style="width:100%" cellpadding="8"<br />
| [[image:TRV_microbore_01.jpg|center]]<br />
Insert a fitting reducer into the valve so that the olive sits in the middle of the reducer (see pictures of the soldered-up connector, below) and tighten so that the olive grips the reducer.<br />
<br />
| [[image:TRV_microbore_02.jpg|center]]<br />
Line up the TRV body with the existing valve body and mark the microbore for cutting to fit into the reducer.<br />
<br />
| [[image:TRV_microbore_03.jpg|center]]<br />
Cut the microbore where marked: in this instance a junior hacksaw is used as there isn't space to use a wheel-type cutter<br />

This avoids the difficulties that are likely to occur trying to fit a new 8mm or 10mm valve to existing pipework: because microbore copper is very soft the pipe is often found to be distorted when the old valve's olive is removed making it very difficult to get a good seal to the new valve. Even if the pipe is not distorted it is very easy to over-tighten microbore compression joints resulting in leaks. Because this method uses soldered joints the heating system must be drained down to below the level of the valves being replaced.</div></td><td class='diff-marker'> </td><td style="background-color: #f8f9fa; color: #202122; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #eaecf0; vertical-align: top; white-space: pre-wrap;"><div>The approach described here uses a standard 15mm valve and a soldered 15mm*8mm or 15mm*10mm fitting reducer (e.g. [http://www.bes.ltd.uk BES] 6786 or 6787) to connect to the microbore.
