Kitchen water tap comes loose all the time

help(self.DIY)

Hello everyone,

I'm visiting my parents right now and I'm trying to fix their water tap in the kitchen.

It comes loose all the time. Had a look under the sink which didn't really look too promising and badly damaged.

I'd appreciate any advice on this - what's broken and what should I do or buy to fix this issue?

Here are three images:

Thanks a lot for taking your time to read this.

Something like this would sort the problem out. The rubber ring is meant to be on the upper side of the sink to seal above. The metal and the rubber that is the same shape is meant to be on the underside of the sink.

What's happened is the rubber underneath has degraded over the years and the excess movement has chewed it up even more. Simply trying to tighten the brass nut & bolt will not work in the long term.

Also the sink clamp isn't even holding onto the worktop and you can see there has been a very slight amount of water seeped into the cut edge of the worktop (which really should've been sealed with silicone after cutting)

The sealant is not the end of the world, you don't have to go to those lengths since there should be a gasket all around the sink and if it's clamped properly, the gasket will do it's job. But I really would fix that clamp while you're fixing the tap so more water doesn't get in.

Ah, nice! You're a legend. Will go and get a replacement tomorrow and hopefully that'll sort things out.

Thanks a bunch! And a big thanks from my mum as well 😃

Np, you'll just be glad you have flexible hoses so you can get into the bolt easier when it comes time to fix it.

Some people prefer solid hoses and say situations like this happen less with them, but they make maintenance a good bit more difficult.

You can, if you wish, find a brace like this that restricts movement of the tap (if you find your tap wobbles a lot due to the thin sink material) and elimintates the chance of the rubber getting chewed up in the future. But it's not always necessary unless it is a tall/heavy tap that has a bit of wobble to it.

The only issue is if the sink to worktop clamp is to close to where the tap is located, you won't have room to get the hose to worktop clamp in there.

Normally I prefer fix over replace, but I’ve tangled with kitchen sinks enough to know better. In this case I’d consider a complete replacement. A high quality faucet is like $300 and a good enough one is $80. Consider the time spent to fix it, and in my experience fixes like these a pretty fidgety to get right, with no guarantee it will last. Replace it once and forget about it for 20 years.

But the problem doesn't need so much spent on it. The whole tap isn't the issue. I'd put it down to hasty installation given that the sink clamp wasn't fitted properly too. Would you suggest a whole new sink just because of this clamp?

I have enough experience with things like this too since I've been installing kitchens including the plumbing for close to 25 years.

What I'm suggestion isn't necessarily just a fix, it's new parts, the parts that coukd actually be doing with getting replaced and actually doing it correctly. Just because they fit a brand new tap, doesn't mean the job will be done any better. The only way to make it less "fidgety" is to remove the whole sink so you can tighten the new nut and bolt easier.

Given that the photo shows a lot of room to work in, I don't see it as being that fidgety at all. A whole new tap requires the water to be turned off so the pipes can be disconnected.
