Waterfall tap: seal between basin and tap leaking

[Ulsinus]

Hi!

As part of a refurbishment I had a new basin and single Plaza waterfall tap from Victorian Plumbing.

The seal between the base of the tap and the top of the basin is ineffective and is prone to leakage in certain circumstances.

I've given up trying to get the plumber back to resolve. He's big on promises but bad on delivery.

That being the case I thought I'd sort it out myself but Victorian Plumbing can't supply a copy of fitting instructions. They claim they don't have any!

Before starting I'd like to know what I'm letting myself in for.

Grateful for any help, advice and guidance that forum members are willing to give.

Thanking you all in anticipation.

The nuts are different sizes on different taps.
You need to get a monobloc spanner set

Will do. Thank you.

I bought a set of MONUMENT TOOLS MONOBLOC SPANNER SET as recommended.

Just the job and well made.

It proves once again that having the right tools can make all the difference.

The nuts on the tap were 9mm.

I had a bit of a problem with getting the tommy bar in to turn the box spanner but got round this by using a ring spanner on the other end. A 14mm ring-key worked just fine.



Sadly the tap washer nuts were corroded on to the studs so they can out in their entirety.

Not the end of the world.

To get access I needed to remove one tail which was straight forward enough.

Once I had lifted the tap off the sink the cause of the problem was clear.

The tap needed to be pushed back about 5mm so that the sealing ring was properly located on porcelain of the basin.

I decided to use the grease approach this time to help make the seal. (I figured if this didn’t work I can go back and use silicon.)

So I used Vaseline as the grease.

I clean the O-ring, base of the tap, and top of the basin.


Drew a line withe pencil to indicate the revised location of the tap. I then applied Vaseline to the O-ring and base of the tap and reassembled everything.

Job done.

Leak cured and thank you to all the forum members who helped me withe their comments and advice.
