Personaly, I think TRVs are one of the few plumbing items I think it is worth buying a brand name for. Christian. |

I'd be cautious about buying any 'Reversible' TRV's from Screwfix.
I bought 10 from them (they don't appear to sell the type I bought any more, & I can't remember the manufacturer) I ended up having to reverse more than half of them - what a pain in the a**e !!!. CG... "Mr Fizzion" wrote in message ... http://www.screwfix.com/app/sfd/cat/...30518&ts=77832 |

I've had Wicks and Homebase own brands fail after about 5 years, but the current Drayton ones have passed that deadline and still working fine. -- *The more I learn about women, the more I love my car Dave Plowman London SW To e-mail, change noise into sound. |

My view too. You don't want the hassle of draining down the system
again because cheapo TRV has failed. I've foundt he Pegler ones SF sell ( Item 23130) are good. |

Hi Guys, interesting thread, I didn't know that there was such a variation in quality on TRVs and have always just used cheap 5 quid jobs. Just wondering what you all mean when you say they fail - I understood that they all have a limited lifespan something do to with the wax capsule or something, and therefore the heads will need to be replaced after a number of years. Is this what you're referring to? I don't get it as surely the heads just unscrew and can be replaced without draining down? Or do the valves fail too? Cheers, Ben. |

With a branded valve, you're more likely to find a compatible replacement head in 10 years time, than you are in 5 years time for some unbranded make. Christian. |

Typical ones: - valve body mechanism jams because of poor manufacturing tolerance coupled with crud in the system. - seal on valve begins to leak - wax capsule fails and the valve locks on, off or simply has no thermostatic action. If you take a product like the Invensys TRV4, it has been available for at least 25 years and the capsules last a good 7-10 years at least. I have some that are 15 years old. You can buy the replacement heads and swap them out. often it's cheaper to buy the complete valve and not bother replacing the base. On the cheap ones, failure usually means changing the whole valve, base and all because often they have a proprietary fitting. -- ..andy To email, substitute .nospam with .gl |

Most of the cheapies I have found tend to give a high pitched squeeling on the last bit of the close. in-audible to the slightly older generation, but a PITA as it can last several minutes. The ones on our very old and being replaced radiators are "Myson" look as old as the rads themselves, but definately in excess of 10 years, and worked exceptionally when the old system was in operation. -- http://gymratz.co.uk - Best Gym Equipment & Bodybuilding Supplements UK. http://trade-price-supplements.co.uk - TRADE PRICED SUPPLEMENTS for ALL! http://fitness-equipment-uk.com - UK's No.1 Fitness Equipment Suppliers. http://gymratz.co.uk/hot-seat.htm - Live web-cam!
