Get to know this board a little better havac.
There are some genius people here ,but you won't get anywhere with a bad attitude.
Dude, how big is this system? How long is the line set? 18 pounds seems to be A LOT of refrigerant for a residential unit. If the leak is that small, you shouldn't have to worry about contaminants getting in the system. If you have access to a Total Line tester with the glass tubes, they will check for moisture if I am not mistaken. It's been a long time since I used one. Unless the system isn't running right, aside from the leak, just wait until you fix the leak and put a drier in it then.
How do you measure 6 oz. out of 18 lbs? I would seriously doubt 6 oz. out of that total would show ANY noticeable effect in its cooling. Especially on a 15 year old system. That comes out to 1/2 oz. per month. I would think you would lose more than that taking your gauges off. Probably that amount hooking and unhooking the filter drier.
6 oz a year for 4 years.....sounds like the coils is gettin a little dirtier by the year.

havac.....your new to the field??? And you want to insult those that have been doing this for better part of a half a century? Try adjusting your attitude and gettin pro status. This is an open forum. No real tech advice will come from this forum.
As far as your question...put in a drier if thats your long term goal. Pump it down....recover it. It doesn't matter. Do it right the first time around and be done with it.
I fully support the military and the War on Terrorism.
If you don't know, then don't do. If you don't know and still do, then be prepared to pay someone else a lot to undo what you did and then do it right.
If you do know, then do. But do it right. Otherwise, you may not be doing it long.

To the OP:As others said,if it ain't broke don't fix it.There is nothing wrong with thinking of new way's of doing things,as you did.It shows that you have an imagination,which is good.Unforunately what you are describing won't work.Sounds like you are newer to the field.All I can say is read lots,ask questions to things you don't understand.I learn't the majority of what I know mainly from reading/asking questions,at this and another forum.This is a great site to learn.You may get a response you won't like from time to time.Hurling insults in response to them solves nothing.As your experience grows and the more logical your questions,the better/more logical the responses will be.My 2 drahmas.

Kinda hard to notice a 6 oz a year leak on a system that holds 18 lbs as its proper operating charge.(big system, or long line set?)
If it only leaks 6 oz a year, it didn't draw in moisture. So a LLFD won't treat the refrigerant for anything.
15 years old. It moves about 3lbs of refrigerant a minute per ton.
A LLFD in a bypass set up as you describe, with the flow adjusted not to interfer with the A/Cs capacity, won't have enough flow to filter or dry the refrigerat running continuous for a year.
So it becomes an excersise in futility.
this is the dumbest thing i have ever read but to satisfy your curiosity the best way to do what your trying to do is install a swivel tee on the liquid line hook a middle hose to one side then a flare drier then your manifold then hook your high side hose to the other side of the swivel tee...but judging how amateur you sound your gonna let more moisture in the system by not purging your manifold properly
It's not a good idea for the refrigeration cycle. There are a lot of closed loop systems that have "purification loops" but it is primarily for cleaning up corrosion particles over time. Not anything with an orifice or txv to protect.
Give a man a fish, he will eat for a day. Teach a man to fish, he will eat for a lifetime.
Give a man a capacitor, doesn't know what to do. Teach a man to install it, now he knows everything.
Thanks for those who gave some clever ideas. And for the cautions. I must say though there are a lot of very unhappy people in this forum.
Sure I am new to the field and maybe my idea sounds ridiculous to some of you, but does that mean I deserve the insults?
Look I make an easy 6 figures a year as a DNA specialist for 20 years now. It took a lot of time, effort and hard work to get to that level. I am very good at what I do. I also work in many other fields, build computers, install Operating systems, and work a bit with networking. I also work a lot with music, digital audio recording, and do some minor repair work on electronic instruments.
For those who had nothing better to say, I just wonder how well you are doing in your line of work? How many times you got laid off or fired for doing something majorly wrong?
I mainly want to do some minor work with HVAC systems, as a hobby or part time summer job, once I get a lot more experience. I really don't care what other people think about this post as far as I am concerned. For those who could not think of anything better to say and only insulting remarks, I really don't give a fly'n... F...... Get a life!!
For those who have given me great advice thank you very much.
If we could just end all the insults I would appreciate it. Better yet lets close this thread. I think I have all the information I need now.

Look at the top of the page at my post.
Why can't you chill?
Hvac guys joke around with each other all the time.
If you can't take some light ribbing,well...........
Thread closed.....you wish
You sound like a little baby.
