CH plumbing - what's this?
Been investigating the CH system (pretty old pumped CH/Gravity HW) before I repair/upgrade it. This device is in the CH flow pipe: http://familyfrench.co.uk/temp/IMG_6761.jpg For reference the pipe it is in is about 44 mm diameter (1 3/4 inch?) The yellow label - along with the makers name and a BS mark says: 10.5/l 86 C (as in centigrade) What is it? -- Chris French |

Or; - a high temp limit to prevent rads overheating and causing burns. With modern controls it is redundant now. |

I'd hazard a guess that it's a non-return valve as my CH system has a weir (But different) valve on it. It looks like it's a normal tap/valve type base but with a different head on it. I recon there'll be a washer/spring type thingumajig in there that lets the water through one way but not the other. sponix |
