Thank you everyone. I took all your advice, and I can happily say that after 11 years of poor water pressure the problem is solved. I can now look forward to my daughters taking their usual long showers which now will cost me more in hot water costs! (A better problem to have than running low on...

I think after reading your response- that my problem here is my definition of "overlap" When I look at the pix, I can see the white tubing underneath the blue ring. I think the blue ring is almost completely covering the tubing (I would call that overlapping) except for about 1/32 of an inch...

Cass: The first Pix looks to me as though the blue ring "covers" the tubing almost completly- maybe 1/32 nd of an inch isn't covered. Mark told me that: The Pix shows the blue ring almost completely overlapped- Mark says only overlap by 1/32nd?? Which is correct?? Thanks Don

sorrry- I can't really tell from the pix. In a nutshell- after the expansion process is complete, and I place the pex on the fitting, Is the ring still only have approximately 1/32 of an inch overlap on the tube?? OR, is the ring completely over the entire tube???

So after the expansion process is completed -the outer ring overlaps the inner tube still only by a 32nd of an inch? And it's only the now expanded outer ring (attached to the tubing by 1/32 of an inch) that actually abuts the fitting? Seems like you would want the ring to completely overlap...

Hi: I'm reading the instructions for expanding the pex tubing to fit on the proPex fitting. It says to slide the ring no more than 1/16 of an inch onto the end of the tubing- then to insert the expander tool. The unexpanded ring and tubing will not initially go into the tools expander...

The pump comes on when the pressure hits 42, and goes off at 60. The tank is relatively new- maybe 2-3 years old. I've never checked the pressure with no water in it.

Your answer above seems to indicate a flow problem for my situation. I'm on a well. The pressure is well above 35. I currently have copper (schedule M) but am going to replumb to Pex (separate issue) because my water is aggressive and I'm getting pitting and pin hole leaks. I'm hoping the...

Can anyone suggest a way for a DIY'er to properly uncoil Pex tubing without buying an expensive uncoiler? Thanks Don

Thanks-I'm convinced to let it go

With the help of this forum I'm about to re plumb with Pex (Wirsbo expander system). I am now also considering adding some fire protection with a sprinkler system since it will utilize the same manifold system. I need some know how advice and some where to get the correct hardware advice...

Well If I wanted to go with copper, could I sweat two of the same diameter manifolds-say 1 1/2 inch in diameter, one with 3/4 inch terminals, and one with 1/2 inch terminals- would that work? Thanks, Don

Manifold Question: Can I gang together two manifolds of the same size copper pipe (using a large diameter say 1-2 inches would be better?)that would have different sized pex terminals i.e. mostly 1/2" but at least one with 3/4"? This is the type of manifold that I would sweat two...

Pex Unroller?? Hello Again: Do I need an unroller, or is there a technique that I can use to properly "unroll" the tubing?? Thanks, Don

Yes I can see that now that I've re read it- thanks. Does this mean he suggests that I stay away from the brass or copper fittings? I see mostly brass and copper?? Don

Thanks for these tips about the manabloc and the Zurn. I'm leaning towards the Wirsbro system and they have a block system as well and I think you can also use the manabloc with Wirsbro. Do you know diameter of the guts of the manabloc- not the fitting for the intake but the interior size??

I've only seen these white rings: http://www.pexsupply.com/categories.asp?cID=537&brandid= Do you have a source for the black one's you mentioned? Are they better than the white, or is it just the contrast vs the tubing to allow you to better see that 1/32" overlap? Thank you for these...

Thanks BAPlumber: Are these the collars that jadnashua was referring to: http://www.pexsupply.com/categories.asp?cID=537&brandid=

So this is the only tool I need? http://www.pexsupply.com/categories.asp?cID=559&brandid= Can you send me a link to these collars, because I don't see them on the Pex Supply site Thanks Don

Gary: Thanks, I'll Triple check on the safety of the water, but my town health official, and all others involved in this process have told me that the water is safe to consume. BTW the water is not acidic, in fact it's about a 7.4 ph Can you give me any help with the questions I raised...
