Well I Think Its Funny....a shaggy dog story

[topgazza]

Carefully pushing my new WC back to the wall onto the soil pipe (s trap) I was very please with the result as the body of the WC hides the soil pipe. Using an isolation valve, short tail and then flexi pipe to the cistern inlet it all looked good.

Shouted to my son down stairs in the cloakroom to turn the mains on and stay there until I told him otherwise. Fine, opened the valve and the cistern filled. Noticed the valve was only 1/2 open so cranked it wide. WHOOSH! The tail and flexi pipe shot off the valve and water, in a rather pretty arc shot across the room. Obviously turned the valve off and noticed I had let a piece of the PTFE stretch across the pipe and not just around the olive creating a very nice blockage.

Lesson 1.....ensure there is no excess PTFE across the pipe /valve openings. Especially with an unvented high pressure system (which is why I don't use pushfit...sensible?)

Lesson 2 ...Don't forget to tell your son that you no longer require his help, as soon as possible. As 45 minutes in a cloakroom gets a bit boring.................

Lesson 3.....Don't use PTFE tape on new fittings (not needed).

 

[topgazza]

I know but its a difficult balance between over tightening and just enough of the spanner. PTFE gives just a tad more confidence of avoiding leaks. However I will try it tonight when I put the sink on...just to see.

gravity eh mmmmm Part L lol

Good luck but DONT DO IT

PTFE gives just a tad more confidence

Not for me, takes away the feel, just like that other micro thin rubber thing I haven't used for years.
When tightening the 'naked' fitting, I find it usually screeches as the olive bites, 1/8 more turn at that point and job done, if not (but usually is) 1/8 turn at a time, done.

 

[topgazza]

Assuming a good, clean (new?) pipe I agree. Any doubt on that then I would still feel more comfortable with some tape.

Going out to search for some 10 x 15 mm flexi hose/pipe with monoblock tap male fittings on the 10mm end. Bit prettier than the copper tails supplied with the taps

 

[bathjobby]

Agreed topgazza, new, clean parts required.
The only DIY shed I've seen the 15mm to 10mm flexi's for monoblock is GA Days. Screwfix on net is a cheaper but only if ordering enough (£45+) to get free shipping.

 

[ChrisR]

BES do them too.

What's the reference to gravity about?
I was intrigued that the chap's using an S trap loo which he's "pushing back to the wall".??

Plumbcenter do the monobloc flexi's. Assuming there's one near you.

 

[topgazza]

Chris, only in so much as insert the 90 degree pipe in the "hole in the gound" and then push the WC onto the pipe bend sticking out.

I'll check the Plumbcenter out..cheers

yeh they certainly do! I need a 10mm and 12mm for a kitchen tap. Imagine my surprise when the invoice turned up for 20quid for a pair!!! Im shopping at PTS in future.

Sounds like a P trap to me!

 

[topgazza]

Hold on a mo!

My soil pipe comes out of the floor so I use a 90 degree soil connector....... Oh, I see the WC is a P trap cos its soil "exit" is straight out, so can go through the wall horizontally or be converted downwards by a 90 bend. Whereas the S trap WC soil exit is moulded to go downwards only.

Trouble with the original toilet I foolishly bought online from B&Q was that it was horizontal only and could not be "converted". Nothing in their catalogue or online gave any indication of what type it was. At least they refunded everything without a quibble.

None of the sheds do a 12mm male to 15mm comp flexi, which on checking is what I need and not a 10mm to 15. I'll keep hunting

 

[topgazza]

Just bought my 12mm male x 15mm flexi tap tails from Plumbcenter HTgeng is right, they are very expensive. Wickes do them, but of course had none in stock, for £6.98 a pair. Plumbcenter charged me £10.60...RIPOFF...but at least I have them and can complete my work so I guess I'm a bit happy
