Will this adaptor connect this pipe to this fitting?

Brimble

Our new water softener has push-fit connection flexi pipes, whereas our old one, and the existing pipework under the sink, does not, they have thread connection (whatever that's called). If we unscrew the hose on the right of the picture of under the sink, will the pictured adaptor connect the new hose to the existing fitting safely? (And is the size likely to be right - I've written the measurements on the new hose, I'm not sure of the measurements of the fitting under the sink, but assume it's standard..?). Also, will it be ok to push the male brass part of the new adaptor into the female plastic part of the push-fit hose? If the answer to any of those questions is 'no', does anyone know an adaptor that would do the job, or how else we should make these connections?

Many thanks

2. New hose with plastic female push-fit connection at the end where we need to connect to the fitting in picture 1.
3. Adaptor that may or may not do the job.

If picture 2 shows the external measurements of the connector then it’s a 15mm connector. An adapter like the one in pic 3 but 15mm x 3/4” should do it.

Alternatively you could change the appliance hose for one with a 3/4 connector on the end instead of a push fit. That would be more secure and they’re not expensive.

That connector looks more like 1/2", not 3/4".

Aha sorry I wasn't clear - the measurements I've written on picture 2 are the measurements embossed on the other side of the pipe (I didn't realise until after I'd taken the picture and gone out for the evening). I assume that changes the answer to the first bit of your response?

Assuming I get the right size, when you say that "should do it", is it safe / reliable?

On your second bit: but if I buy new 3/4 connection pipes, how would I connect them to the appliance? (As that has push-fit entrances to match the pipes it comes with of course). Or are you suggesting I buy new pipes with 3/4 connnection at one end and push-fit at the other end (if such a thing exists)?

Which connector do you mean please? Do you mean the Hep2o adaptor, or one of the fittings or pipes in my pictures?

The thread coming from the blue tap.  I could be wrong but the scale looks more like 1/2" to me.  3/4" = washing machine connector, 1/2" = normal 15mm pipe compression fitting size

Hi Brimble.
Could you confirm details on the existing plumbing, please?
There are two blue-handled valves, and a red one between them. And it's all coming from what looks like Stainless Steel pipe fittings.
I'm guessing that the top blue valve leads to the old water softener? And, what, the return from the WS goes to the bottom blue valve? And the red valve is the bypass - currently open?
What we need to know is the size of that red circled valve end fitting. Could you undo that flexi and measure the valve's thread diameter, please. 
And then show us the receiving connections on the new WS.
And will the WS be going on the other side of that panel? How long do the hoses need to be?
Make and model of new WS?

The existing connector to the blue tap. Molerat’s quite correct. It does look like 1/2” not 3/4”

Is the new hose 22mm at both ends? Identical push fit at both ends?

Sure:

The set up is exactly as you assume. I.E. The blue pipe circled goes to the 'in' on the old softener. Below it (you can just see it in the picture) there is another blue handle pipe, that's the 'out' from the water softener. The red handle is a bypass that we are currently using to have water in the house (hence red is in the flow position, and both blues are in the no-flow position).

I can't easily remove that circled pipe, so I've sprayed some WD40 on it and will try again in the morning and report back.

Here are pictures of the other end of the new hoses that came with the softener, and the connections on the appliance itself. As you can see, the male push-fit ends of the hoses go into the appliance.

WS is Tapworks NSC11PRO. (I mainly chose it because a couple of people in some reviews somewhere said that it directly replaced the old Tapworks model we have, so it was a bit of a surprise to receive it and learn that the hoses are different, but hey ho...)

Brimble

Ok the WD40 worked its magic and I've been able to remove the two hoses under the sink. I've managed to get a picture of the opening that the hose came from, just after the blue handle, and having measured it across as best I can, it seems to be about 26mm (not accurate as it's hard to get to) - does that help? (I think it's relevant for the last question(s) asked by all 3 of you...)

bjorn_toby_wilde

26mm is 3/4”, so the original adapter you posted in picture 3 is the right size to fit both the hose and the outlet. 22mm push fit and a 3/4” connector.

That looks like the best solution. The supplied hoses were made to push fit straight onto a 22mm pipe. You have a 3/4” tap instead. The NSC series instructions say “you may need reducers or spigot elbows to connect”.

The adapter should have a washer inside. Wind  the adapter onto the tap thread until it’s snug by hand then nip it up a little with a spanner. Not too hard or you can damage the washer. When that’s done, push the hose coupler onto the adapter. The collar should click back when it’s fixed but give it a tug to check it’s firmly on before you turn on the water.
