If I was to replace the stopcock and check valve to try and eliminate the problem, would there be enough room in between the pipes to remove and re fit? Just think it looks a tight fit that there would be no room to remove check valve and stopcock once nuts loosened without having to pull on some pipes? Thanks

Hi mate there will be enough play on the pipework to change both the NRV and Stopcock you can get them from any screwfix branch . Cheers kop

Thanks, do you reckon the new stopcock and nrv would be exact same length as the ones that are fitted atm so I didn’t need to mess around with pipe work above or below the valves? Thanks again for all the great help guys

Remove the check valve and hammer the internals out of it then refit. This will help eliminate the valve as your problem and can be properly replaced at a later date.

Will be a straight swap I would guess use the existing nuts if you need to . Cheers kop

Thanks deg & kop. I will be trying it as soon as I get parts next week, now feeling confident that this will be the problem and hopefully get it solved

Please fit the valves the correct way round, should be arrows on the sides.

Thanks, I know I discovered that when I was fitting isolation valves to the small toilet I renovated

Before I even attempt to do this, is changing over a stopcock a fairly easy job for a DIY’r? Could I run into major problems? I fitted isolation valves etc to new toilet and new sink and I managed it without having any leaks etc. Thanks
