Replacing the bath waste

[PetersUk]

So I am currently trying to replace my bath waste. I have run out of ideas on how to remove it.

I have enclosed two photos showing it and would appreciate some advice.

There is a grub screw ,down the hole in the round chrome handle. Remove it ,then pull off the handle. This exposes the nut or bolt that secures the overflow to the bath.

Should be a screw in hole in the top of the knob. Loosen it, then pull knob off. Will be a nut behind knob holding mechanism/overflow to bath.

Too slow.

Many thanks for the replies. I have taken out the grub screw that was in the hole but I still can not take off the chrome handle.

I've attached a photo without the grub screw and a reverse photo of the bath tub.

Spray some wd40 down into where the grub screw was. It is a splined shaft ,and only the corrision or build up of limescale is keeping the round handle onto the shaft. Some gentle persuasion is required !!!

 

[ReganAndCarter]

Yes, as above. That knob definitely pulls off a shaft, but corrosion can make them difficult to remove. Not any easy thing to get good grip on with hand, so may need to hook something on opposite sides of each other under lip and pull/wiggle off. Being careful not to damage surface.

Brilliant!

It's worked a treat as the photos show. Many thanks.

Arrghhh!

As soon as I deal with one issue I get another. How should I remove the stuck bolt in the photo enclosed?

 

[ReganAndCarter]

You need to turn the whole circular piece which sits proud of the bath surface anti-clockwise to unscrew it. Put some grips, etc on the 'x' formation pieces that go from splined shaft out to the circular edge to turn. Then the assembly behind bath with just drop off unless siliconed on. You don't need to turn the splined shaft.

Thanks for the suggestion. I've moved further along with sorting out the bath waste. It's now installed fine but I can not stop a leak from the connection between it and the pipe.

Any suggestions would be welcome. I already have an o ring in place but I can not seem to find a space for a rubber washer as shown on the opposite end of the pipe (see two photos)

 

[terryplumb]

There should be a rubber seal between the trap and the waste. It is not shaped like the one at the other end ,and it is not an " O" ring either. Its flat faced. And ideally you should have fitted a new one before connecting the trap to your new waste.
Edit screwfix do code 40512, " trap seal kit " , and it contains one of what you need. Around two quid.

By the way get rid of the ptfe tape it is not required. It may just be a trick of the light ,but photo looks like the nut is cross threaded. Take care it is aligned properly.

Thanks for the reply Terry,

I have bought a similar trapkit from b and q. Which of the rubber seals from the photo should I use and how exactly does it fit as there does not seem much spare space at the top of the trap for it.

Also if the waste is not vertical and is cross threaded how bad a problem is it? Would I have to redo the bath waste connection to the bathtub?

 

[terryplumb]

I can see the seal in your trap and its twisted. Pull down the plastic nut on the trap ( the one that Screw's onto the waste. You will see the seal ,and the ledge it sits against. Dont think there is one in your bq kit. Its square and flat faced black rubber seal.

 

[PetersUk]

Ok, I'm not sure which item here you recommend I use

https://www.screwfix.com/p/floplast-replacement-trap-seal-black-40mm-4-pcs/40512?_requestid=559728

I think what I bought at b and q is the same item (see photo).

I can certainly redo the seal and untwist it.

 

[terryplumb]

Your first pic only showed 3 seals ,the one you just posted has More ,and the one you need is the black rubber one lower mid pic. Anyway take the old one out it will be obvious. Dont try to re use the twisted one.
