Fitting a Boiler Filter - struggling to find a spot....

dishman said:

But....my question is....If I swap out an elbow fitting for a straight coupler....can I reuse the existing olive. I intend to put a bit of boss white around it....but just wondered what most would do in that situation.

I guess there is enough pipe on that connection out of the boiler to cut the old olive off (assuming the olive it is impossible to remove) and add a new one...

Is the reuse option OK though?

Yes, it's a common trick to remove a fitting, leaving the nut and olive on the pipe, then replace with another fitting. Just check the threads are the same, there are odd fittings about with a finer thread that crop up now and again. (They usually only becomes apparent in this situation when you try to reuse the nut and olive....) Check the condition of the pipework when you undo the existing fitting, if the joint has been overtightened in the past and the olive/pipe have been crushed, you may struggle to get it to seal again, in which case you'll have to cut that section off and start again with new olive.

Boss white never goes amiss on a compression joint.

Yea, as said, usually fine reusing old nut and olive as long as there same size fitting depth and thread.

Worst case, carefully hack saw a grove into olive and split it so you can replace with new fitting without cutting off any more pipe

OK.....this is the result of my work.....thus far




Thoughts?

I had to ensure the horizontal section had enough clearance for the filter...as a cupboard goes around the boiler. So I had to make it as high as possible. Hence the first valve being so close to the ceiling.

I also angled that valve slightly away, as the handles are so long, it would have been close to touching the filter. The valves are bi-directional do it did not matter which way I orientated them.

I have not done a final tighten of all the compression joints yet, But I think everything is correctly in position,(please excuse my directional arrows on the nuts. With so many joints in close proximity, not doing this for a job, it is easy to forget which way is the correct one to tighten ) .

My biggest concern is getting the tightness of the joints correct. I guess that comes with experience.

And in case anyone wondered....yes...I ensured all the ends going into compression fittings were all clean of paint and debris to ensure a good seal.

The one connection that does have me concerned is the first coming down from the ceiling. As this pipe had been bent further down, I think there was a bit of warping further up. But...the compression ring fit tight...and I used some boss white...so am hopeful it makes a good seal...I hope!

I know that I used yellow handled valves. But, after checking, they are suitable for water applications. In addition, a lot of the other valves with the correct coloured handles did not seem to be full bore, which these are.

I'll put a bit of red tape on them. To be honest....it may make someone less likely to turn them off when the boiler is running.

I might be stating the obvious here but the filter housing should be pointing down.

How do you mean? Fernox say the housing can be positioned horizontally or vertically....as long as the flow arrow is going in the correct direction.



I have not finally attached the filter itself yet....which does point down...but this is what it looks like when in situ. I can't see any issue when compared to the installation instructions.



Please excuse the odd angle...

But....If am still misunderstanding something....please let me know.

Ah, my bad. I must have had a brain fart. I thought the top was supposed to be pointing down. Feck knows why - I have the same filter myself and I only drained it a few days ago! I didn't use valves on mine but for safety's sake, you could always remove the handles on yours and only fit them back on when you are draining the filter.

Haha, thanks anyway.....you only gave me a minor heart palpitation for a moment.

To be honest...without the filter attached....it probably looks odd.

I assume everything else looks OK?

My only concern at this point it getting the compression joints correctly tightened.

If you fill it up and they leak, just nip them up some more!
