Imperial (maybe?) bath pipework

[Andrew Mawson]

Unusual, but perhaps 1" - which will mate with 28mm fittings iirc

Ive spent the day replacing my bathroom suite and i've come across

significant problem.

I've successfully replaced the hot water tap on the bath with a 22m flexible hose with a compression fitting on one end.

Ive just cut through the cold water pipe and now discovered that it i not the same size as the hot. Its too wide to fit the compressio fitting onto.

The house was build in the late 40's so the original pipework i obviously imperial, but clearly its not 3/4". Its at least a couple o mm wider than the 22mm compression fitting and everything ive read o here says that 3/4" is smaller.

I'm stuck without water now. Has anyone any idea what size this pip might be and if i can get anything to convert it without having to cal in a professional plumber

If it's only a couple of mm bigger than 22mm it's inlikely to be 1" imperial - which is nearer to 28mm.

What's the pipe made of - it isn't lead, is it? If it is, you can get special adapters - leadlok or somesuch - for joining lead to copper.

If it's that close to 22mm, can you slip a piece of 22mm inside it and solder?

When I did my bathroom I bought a metric/imperial endfeed reducer to soder in for that very problem. Cheers. Martin

What was the pipe made of?

My house is built 1949 so I'm thinking maybe 3/4" steel pipe? The OD of that would be around 25mm. The usual procedure is to unscrew it at a suitable joint and use a brass fitting to convert it to 22mm compression. Or thread the end with a die set (last resort).
