I am doing a DIY job - fitting a new inlet valve - "Viva Skylo Bottom Entry Fill Valve Plastic Shank" 1/2 inch.
The existing pipe to the underside is copper with an olive and nut and fits reasonably well, and is watertight. A dribble of water went in and then stopped.
The inlet pipe on the valve is black plastic (I know some like brass more but that's not the problem here.) I see that there is a white plastic part in the pipe here that is almost level with the end of the pipe, and has a disk that leaves only an annular aperture around the inner circumference of the pipe for water to pass through. Perhaps this is a pressure reducing part? At any rate it seems to me that a copper pipe with an olive might not work, in that the end of the copper pipe will push up into this gap and seal it.
Should the connection to the inlet valve be something with a washer on, which presses against the end of the inlet pipe? That is - the same sort of fitting as a washing machine inlet? If so, should I get a stretch of flexible pipe, I see them at 150,200 and 300mm, some with an on/off isolater too (though there's already an isolater on this?
Any advice gratefully received from you experienced professionals. I think I'd be unwilling to try copper pipe fitting, with a new stretch between the on/off and the inlet valve. I'm not sure either if I understand the 15mm - 1/2" element with these pipes, but that won't be what's causing my problem, so if I can work out what's wrong first I can address the solution.
Thanks all - Abe
