Afternoon all,
I've moved into a house that has radiators with twin entry valves connected to 10mm diameter copper piping. I want to replace these valves with TRV's, so I called a few plumbers in to give me some quotes.
three of the five plumbers said it should be a simple swap, just drain the system, replace the valves, extend one of the pipes to the other side of the radiator, refill and balance. However, two of the plumbers said that the 10mm pipe will need completely replacing with 15mm pipe to work with a TRV. Can anyone tell me if this is an accurate statement, or is it the plumber trying to fleece me for more work?
One of the two that told me that, also said this would be needed as it is not possible to flush out the system properly with 10mm pipes.
I'm half tempted to have a go at replacing all these TRV's myself, is it a job that can be handled on a DIY basis, or is it really something for an experienced plumber? The heating system is running off a Worcester 28cdi combi boiler....
Thanks
Andy
