Does it need a washer?

[Pete]

Just connecting  hep2o fitting and just wondering if it needs a washer in the bottom? It does not come with a washer and the bottom seems tapered so I guess not but just thought i would ask anyway. TIA

what's screwing into it? Flat faced or taper?

[ProDave]

Reading between the lines you tried connecting it just with ptfe tape and it leaked?

 

As above what is it connecting to?  if it's a tap, it's probably the wrong fitting for instance.

No, I put a washer and some thread sealant. It attaches to the back of a geberit toilet isolation valve and it is flat.

One to the other!!

Half tempted to try without the washer.

Wrong fitting   You need a tap connector not a female 1/2” BSP as shown. The tap connector will have the seal inside it already ( assuming Hepworth ) so nowhere to go wrong.

That needs a tap connector,

And will be used with a fibre washer

Also, make sure you’re cleaning out all the bits of goop and PTFE tape as they’ll go into the float valve and cause it to fail early.

As above. Fit and forget.
