Don’t use a coupler; the sharp tapered edges, designed for an olive can cut into the rubber washer. Use a hexagon nipple which has a two flat faces. You could always file down the coupler if you don’t have a nipple. 👍🏻
Brilliant video thanks for the wonderful videos they are all so well documented. Your certainly the best plumbing advice on u tube . Don’t ever give up posting these your vast experience is priceless.
love these videos you have 245 views but thats not really views its people helped. these kind of videos are a great force for good argument for youtube
They are you could argue the best plumbing invention ever.I have uses them for years without issue other than as you say the isolator variants which are not reliable after time.
I don't like using couplers or normal compression isolators the sharp edge cuts into the washer, it does generally work but the washer is then goosed and if for whatever reason the flexi is removed in future and the washer not replaced could lead to problems.
I removed as many of these flexis as possible since our bathroom plumbing is tank fed. So I wasn’t sure if this video was sarcasm or not 😂. For mains and combi systems, these are great
I love these flexi-hoses. I use a lot of push fit ones aswell. Example:- Last year I plumbed a kitchen sink (hot & cold) + 2 cold feed dishwashers & a washing machine, all in a line in around 2 hours, going through 4 base units. In copper, the job would have taken 12 hours & knackered my back.
One of these sprung a leak under my sink. I was very lucky as it happened just before I was leaving for work. I'd recommend if you fit these to inspect them every now and again for rust and other damage.
Same thing happened to me. I think the trick is not to have too much slack so they flap about which they do when water flows through them suddenly. That stops them rubbing on things.
On my bathroom sink the flexi got damaged by the plug lift mechanism, one of those ones where you push a knob and it lifts the plug up. Flexi pipe would move when turning the water on and off and rubbing on the bar of the mechanism. It damaged the mesh and the rubber inside started to protrude and there was a pinhole leak which I caught in time. Moved to a toggle sink plug now. Got to make sure these pipes don't rub against anything in use.
My brother-in-law is not so keen on them. The metal sheath puctured the aged pipe inside and caused a right flood. Go for a proper pipe connection if you don't want to coming back from two weeks in Benidorm and find a huge swimming pool where your house used to be. I agree that they are a good short term solution for tight installations though.
I have had some installed for over 15 years and they are still fine. He must have bent the flexi too tight on a bend causing the metal sheath to cut through , bad plumbing.
Absolutely hate flexis 😂😂😂 i prefer bending copper nice little 90's offfsets or kicks 😍😍😍💯 or use flexible copper sticks 👍🏿👍🏿the speedfit flexis are okish but anything speedfit is about 2-3 times expensive #copper is proper
Don't use Flexi pipes 😮 they don't last and cause many many fluds and very often fail during the night as water pressure increases when your not using the water system. The flexi used on hot water connections are the worst for failing.
You have been very fortunate. I have seen many instances where the hot feed has failed due to water ingress to the braid and corroded it breaking the braid and the pipe inside stretches and fails. DIYers tend to twist them on installation which also shortens their working life.

Never had a problem using couplings. Sharp edge or not. If you look at a typical tap thread it has sharp edges.
@@dereton33 I agree. Not had any issues thus far. As long as you don't overtighten it's fine.

Wow, thank you!

Great happy video, as usual, Al 👍
Thanks Rob.

Thanks, I have no problems. I replace the washers any way if i have to remove them.
Very good advice Al.👍👍👍👍
Thanks 👍

Just get the bigger bore flexis for low pressure.

I bet it looked beautiful
That is where they excel, thanks Mark.
Good video. Hope you, Jan and Mo are well
Yes we are, thanks Sam.

Thanks for the tip. Everything has it faults, I have some in my house over 16 years old and are still fine.

Ha ha thanks.

Should have mentioned they should be well fixed.
I've got the same situation, there is a rub mark on the braid but no rubber showing yet.

Thank you for the video, could these be used on a bathroom radiator? Thank you
Not on heating systems anywhere.
They have moved on a bit, ten years or so ago they were prone to splitting, seems less often now, just don't kink as Al said and all should be well.
Thanks Colin.
I find isolating valves okay if they are reasonable quality , but I live in a soft water area , I bet in your area its probably bit hard.
No my area in Devon is also soft.
@@dereton33 Oh well stay away from low quality ones then. Mine are okay and our water is a touch acid.
I've never seen one of these close up, how does the flexi connect to a copper pipe?
Using a standard nut and olive like compression fitting 😋
Can you use these on the bottom of towel rail radiators? Ive put them on but worried about bursting?
No never use them on heating pipes.
We have one of these on our toilet but I'm guessing it's not the done thing as I don't think I've seen it anywhere else.
They are pretty much everywhere now days Sugar Puff.
@@dereton33 Thanks Al.
Flexi's have a smaller internal bore than 15mm copper internal bore so can slow down the water flow if water supplied from a tank.
Best to get the larger bore flexis.
They're ok til the washer fails.......usually in an inaccessible place
There is always a flaw on everything you fit.

@@dereton33 i like to get my pipe bender out regularly and give it a good hard pulling 😂😂😂 especially on 22mm💪💪💪 after my weetabix

Disagree I have never had a problem with them. Fitting hundreds and never had one fail.

I wonder what ever happened to proper plumbing practices. Oh yes, takes too much time and EXPERTISE, silly me.
That`s modern life for you, everything has to be done in half the time.
