Pool Plumbing

[alarm_guy1]

Hi guys,
Hopefully someone can help, I'm in the UK and have an Above ground pool Bestway, I have my pool plumbed in standard domestic 40mm pipe, however I have just purchased a MEGA 1\2Hp pump and the fittings that come with that are thicker walled pool plumbing, is there a reducer to reduce down to standard 40mm, and if so where from and what would it be called

Many thanks in advance

Any chance of a pic? I'm having a little trouble converting to metric :-D

Yeah, me too. I thought that pipe was one of those things that was almost universally inch measured. Even British Standard Pipe (BSP) sizes are inch. I guess 40mm is almost a coupla mickeymeters shy of 1-1/4 inch (41.9-ish mm).

We'd still need to know the pipe size on the MEGA.

40mm is 1.57" we are in complete limbo in the UK, We can get a mixture of both, DIY stores only sell 40mm and trade shops sell both flavours. the internal diameter though is not the question.
The external diameter of pool 1 1\2" is much greater than that of uk domestic plumbing, all I need to know is it there a reducer available?

According to my calculations 40mm is about 1-1/2" pipe. I don't know what size the new pump is but there should be adapters to change from one to the other. The trade shop is where I'd start searching.

40mm is about 1-1/2" pipe

Yes, you are correct, and I, of course, am a dufus. I should have typed 1-1/2, not 1-1/4.
