I think this one single part will actually achieve the same, but probably not hang down that far......

However it is not ideal wshere I need to use it, and managing to go sideways rather than downwards is definitely preferable

Batavia's all brass solution is probably ideal, though clearly not achievable at anything like the £5 you mention!  However I hoped to solve this quickly, and couldn't find the bits I needed withou having to pay heaps extra in carriage.

OK see the post below with the McAlpine S1, £2.49 gets you a 90° bend..

Another option is a McAlpine S12C then a McAlpine MA15, both available from PlumbCenter:

OK it's 45° not 90° and the hose tail is 20mm not 19mm, but probably close enough, and at  £4.89 all in, so it's within the £5 budget! Yippeee!

OK means a a wait of a day or so for click n collect, then a traipse to the local branch (usually somewhere near a screwfix), but not bad going, handy for cc'ers...

TLDR: McAlpine has some obscure but handy bits which are nonetheless somewhat available:

Do you reckon this is the same, please?

https://www.screwfix.com/p/floplast-shallow-bath-trap-white-40mm/13034

I ask, because the thing I already have is branded as "Floplast", so might increase the prospect that both bits have similar threads.
 

 

 

 

Yes. I BET your hose tail adaptor will screw onto the outlet of your Flowplast trap. Try it!

P.S. "It ought to be called "Flowpast", not ""Floplast" I reckon!!!

 

Another day, another fail!

Yes, the adaptor to a hose tail will go perfectly on the left hand side of this fitting.

HOWEVER:

Without modification the right hand (1 1/2" BSP end) will not correctly join to the male part of the 1 1/2" to 1 1/4" brass reducing bush I already have in my growing arsenal of plumbing bits

The end of the pipe has a stepped end on it, intended to fit inside the drain outlet it is being attached to.  The internal diameter, (over threads) of the reducing bush is a lot smaller than the smooth interior of a 1 1/2" drain would be, so the bloody thing will not fit into it, and settle down onto it such that the raised lip on the pipe end actually touches the reducer.

I feel an enormous bodge involving a Dremel and large amounts of silicone leak sealer coming on at any stage.

Or next try could be the "McAlpine S1", but not being a Screwfix item that either means another journey somewhere, or another enforced wait for it to be sent out by post.

Screwfix do an S4U which looks to be basically the same thing, in stock at all the branches near me, plus it needs a bit less vertical depth:

Thanks,

You must live in an are where Screwfix as a different stocking policy.

At all the Screwfix outlets near me this is an "order today, but available for collection tomorrow" item. Exactly the same in Northamptonshire at all outlets near to the boat.

Seems I may have to wait an extra day to try again!

Yeah my bad all the branches near me say available to collect... next day... 

Still an extra day's wait isn't too bad.

It might still get there tomorrow if you order now.

Not according to their website!

Fairy snuff. 

I see it had to be ordered before midday on a Sunday.

'Tis strange the problems DIYers run into that never occur to people like me familiar with plumbing. 

I would take a nice sharp stanley knife from my toolbox and pare off the upstand you mention, that the thin black washer is positioned over. Once the upstand is completely gone and the surface is nice and flat, the trap you have now WILL screw onto the male part of the bush.  Seal it using a neoprene circulating pump valve washer fished from the bottom of your toolbox, or if you don't have one, a smear of LSX.

Yeah - if in doubt use LS-X. (A "smear" for small mismatches - half a tube full if things really need a large gap filled!

I was astounded that Toolstation don't list it, (or so said the man in the Milton Keynes branch).  I assumed I wasn't the only one so highly reliant on the stuff!

There should never be a large gap. If there is, you're doing it wrong.

[WotEver]

Is LS-X better than Plumbers Mait?

YES is too small a word! 

YES

[alan_fincher]

Generally I'd agree, but for example on the bath that came out, the rough GRP surface that the waste outlet had to be fitted against was so uneven that even the thickest washer I could find would not squash down enough to fill the gaps.  A smear of LS-X didn't solve that at the first attempt, but using rather more did!

Arguably I suppose I could have taken a rasp or file to the bath surface to make a seal without a bodge more likely, but the bodge seemed the lower risk solution.

[alan_fincher]

 

Is LS-X better than Plumbers Mait?

Totally different products, but yes, absolutely.

The one issue i have with LS-X, being an occasional plumber, not a regular one, is that once a tube is opened, you can never predict how long it is likely to stay usable for after that.

However well you re-cap them, the product will just cure in the tube, and become unusable. (Not uncommon for any silicone based sealant, of course).

Hence if I'm going to the boat, knowing I'm doing a job where it might be useful, I invariably spend another five and a half quid for a tube to take up as a precautionary measure, in case the last used one, still on the boat, is no use.

I repaired a crack in the side of my leather ex waterproof boots with the remains of my tube

Well is it sorted now, if so how?

Or have you given up?

More family issues have so far stopped me getting back to the boat......

I have some bits at home, some there, and until I look at exactly where the pipes need to go in a limited space, I'm not sure which method I'll be using.

I will update the thread as and when something is in place.
