Speedfit Hot water pipe fittings

[AntigravityP]

Recently the hot water pipe connection in the picture popped off without warning and dumped litres of hot water into the van. - Not good!!

I haven't seen a pipe end like that before, does it (the white bit on the end of the red pipe) just push in to the connector? How do I make sure it doesn't just pop off again? It doesn't seem to want to go in very easily. I haven't seen this type of end before, I thought you just put the end of the pipe into the connector.
The van is a 4 year old Swift Escape and the pipe is under the bathroom sink where the hot water splits for the shower and tap.

I hope that makes sense!!

Yes it has come out of the push in fitting - (you can see the teeth marks on the nylon) it looks like the nylon is an adaptor which possible screws onto the red flexi pipe. The pipe that has come out is probably quite flexible, I think it needs some way of securing it to stop it coming out again. for piece of mind I would change the Y piece (John Guest) Screwfix Toolstation etc sell them, probably also worth trying To get rid of the burrs on the plastic but be gentle!

This looks to be a John Guest Speedfit joint. The hard plastic pipe that is loose is replicating a copper pipe. It needs to be pushed fully home and the collar on the joint pulled upwards away from the joint. This should cause the joint to become watertight like you see the others. It should not become loose again.

I would say from your photo that the pipe is somewhat short, therefore putting a continuous pull on the connection. It has held for 4 years before finally giving up. When you re-connect you need to remove this pull. You need to be able to lay the pipe and connector alongside each other before re-inserting.

It is Important that the pipe is fully inserted into the fitting, it should pass through the O ring and butt up to the stop. The o ring provides the water seal and the collar holds the pipe. Hopefully this pic. Will help.

some clips like this could be used to stop the water pipes from moving.

Does the nylon bit unscrew from what looks like the tap tail?. If so it's an adaptor to fit in the y piece. As someone else said I wonder if it's been under a bit of tension since put in the y piece looks like it's got a hole so it can be screwed in place to stop it pulling on the pipe I wonder if it was missed off. I think id be tempted to try the fixed y piece with jubilee clips

You can purchase a clip that goes under the moveable collar when the pipe is inserted which stops it slipping down and releasing the pipe.

It would not be the tension that releases the collet in fact the opposite possible when travelling the pipes flexed and under compression of the collet it released? thus my suggestion of collet clips

 

[namwaldog]

It looks like the circular collet at the top of the fitting on the left hand side is in the 'release' position.

You have to push this collet back into the fitting to release the inserted pipe.

You can buy locking clips that stop the collet being pushed back into the fitting.

Collet Locking Clip

Prevents accidental disconnection of a Speedfit fitting. Locks collet into position.

It doesn't look like there are any locking collars fitted to the remaining joints?

It does look rather short.
Acquire a short, couple of inches, length of red pipe and a straight John Guest connector.
Put the connector on the nylon stub and the red pipe goes between the Y and straight connector.
Ensure the pipes are FULLY pushed on.....they will go so far on then resistance will be felt. ..KEEP PUSHING until the last ½" goes in.
The lock collars will pop out on their own if you pull back on the pipes

this style of speed fit was available with locking clips to prevent the collet in the fitting from being depressed by anything. Now the Speedfits have a twist & lock system which prevents the collet being depressed. These later fittings are bulkier than the style in your picture. So long as the rubber or the collet in the fitting are not damaged they can be fitted & disconnected many times. To lock the fitting you have:

In addition to the good comments above - the Y pieces also have a hole in them to allow them to be attached to a surface with a screw. This reduces vibration, and movement of the Y piece / flexible pipes from swinging around.

Thanks guys for the useful advice, The pipe is definitely a bit short, it is quite a tug to get it down to position and it must have been in permanent tension all this time. I am concerned that if I just put it back it will still be under too much tension. I think I will try and get a bit of pipe to extend it to take the tension off and the clips look like a great idea, I didn't know you could get them.

it might be better to shorten the top pipe to make it the same length as the one that has come out and extend or replace the supply in from the bottom. You need a proper pipe cutter to get a clean, square cut that will seal properly, don’t try using sidecutters!

And has as been said on previous push fit pipe threads if you cut flexable pipe use the correct diameter pipe inserts so you have a nice round pipe for the fitting to grip onto.

Had same problem as you with our Swift.
Pipe is definitely too short and being hot water side becomes pliable. As it is under tension it just pulls apart.
Ours came apart in France but luckily I managed to reposition the plastic tie down clips and get more length to the pipe and it pushed back together.
A certain amount of cursing was heard at the time as it was dark and the only access to the offending joint was through the outside locker as the pipes ran behind the kitchen unit.
Must say I was not impressed at the time but no further issues after.

As said get a bit of slack on the supplying pipe work, instal your loose pipe. Then put a screw through the hole in the junction, to take the weight off the pipe joints.
