Changing a tap washer

(8 Posts)

Any top tips?

I think I know how to do this. Turn the valves off below the sink, so that water doesn't spew out, when you undo the tap.
Undo the tap handle, take out the old washer, put in the new washer, replace tap handle.
Open valves again.
Job done?

Do tap washers come in different sizes? I don't want to be back and forwards to B&Q. Actually that's a point can you get washers in B&Q or will I have to find a plumbing supply shop?

tap washers do come in different sizes. Most likely 1/2" basin or sink and 3/4" bath.

Most are flat, some are domed.

Start with the flat ones. Buy a roll of PTFE tape. Assume you already have a green nylon pan scourer and a limescale-spray.

If you see white silicone grease, buy some.

Does your tap have a knob or capstan that screws up and down?

Or a quarter-turn lever?

Put the plug in before you start work in case small parts fall down the plughole. Lay an old towel over the sink so it doesn't crack when you drop your spanner.

Thanks for responding PigletJohn.

The tap is a capstan screw type.

What do I need the PTFE tape & silicone grease for?

Silicone grease (if you can get it) for the turning and sliding parts inside the tap after you have polished them with your green scourer, ptfe tape to seal the screw thread where the headworks screw into the tap body, and prevent it seizing.

If I can't get silicone grease, is there anything else I could use?

I remember my Dad used to have a tub of browny goldy looking gunk that he used to apply in situations like these, but I have no idea what it was and sadly he is no longer around to ask.

Not that I know of. It is ckean and non-contaminating.

You are probably thinking of Copaslip, which is not suitable.

If you clean up the brass it will probably be OK.

Thank you.

I have a dispenser of it that would probably last a lifetime.

So little is used that many places don't bother stocking it.

It's food-safe and can be used on drinking water taps.

It is a bit expensive but you only need a tiny smear. It's quite thick and sticky and makes taps turn pleasantly.

There is a silicone spray used in the motor trade that AFAIK is not the same and not food-safe.

There are a few sources outside the plumbing trade.
I found these ads but you have to check it is the plumbing version.
