Using this https://www.screwfix.com/p/fluidmaster-button-cable-dual-flush-bottom-inlet/58353 I've replaced the flush and inlet valve on one of our toilets and there is now a small leak from the inlet, where it connects to the cistern. It's an improvement from the constant refilling - but obviously a leak is still not good!
The inlet hole is a fair amount larger than the inlet pipe, but the rubber washer does cover the hole.
The original valve was pretty much identical to the new one, though I wouldn't be surprised if it was the original from 30-40 years ago. It was packed out with a bunch of clear sealant. Watching a couple of YouTube videos, it seems this stuff is not necessary, and perhaps even bad practice, but I'm wondering after reading another thread if it may have been to compensate for the straight pipe pulling on the inlet valve?
The water supply pipe is straight up from the floor with a slight bend. It doesn't naturally line up with the inlet, but it's not pinging away under a lot of tension, more just the weight of it causing it to sag away.
So I'm wondering what is wrong here. I've seen some inlet valves come with a tapered seal, like this: https://www.screwfix.com/p/flomasta-bottom-entry-brass-shank-fill-valve/5527f, and with the way the valve sits in the hole I'm wondering if this is what I need? Though the negative reviews and price make me question its reliability. Or should I replace a section of the supply pipe with a flexible one so that isn't pulling on the valve?
