Hi!
I seem to have a very small leak in one of many line leading away from my ManaBloc distribution system. I need to do an air pressure test to identify the culprit and snake in a replacement. For those who may not know the ManaBloc, this link (http://www.viega.us/cps/rde/xbcr/en-...(ManaBloc).pdf) shows the design. I would prefer to not cut off the connectors that are already attached to the tubing (if possible) and would rather do the pressure test with the existing connector.
Does anyone know either: 1) a source for a tool that allows me to do the pressure test with the current connector? or 2) How and where to purchase the needed parts to construct my own pressure test adapter?
Thanks for all possible suggestions!
Vince

you will need some sort of an air compressor that will get you to at least 100 PSI. then you need to adapt the compressor outlet to hose threads. then a washing machine hose from that to a hose valve on the water pipng.
lastly you may need a spray bottle of bubble solution if you can not hear the leak hissing.

Thanks! I do know how to do a pressure test. What I am looking for is the necessary "adapter" that will allow direct connection to the outlet tubes. I do not want to remove the current connectors to the ManaBloc if I can avoid it.

What is connected TO the outlet tubes? IF they are just capped off, remove the caps and install SOME KIND of fitting that is compatible with your air hose. Personally, for that small of a leak, I would energize the system with water.

you go to one of the pex pipes sticking out of the wall, cut it and put a 1/2 inch pex by 1/2 inch female adapter. then put a bushing down to 1/4 for the compressor hose to screw to.

That is a good idea - attack it from the other side since all of those connections are NPT. Great idea! Thanks!!
I am avoiding water since the tubing is enclosed in completely finished walls and I do not want to make the situation any worse.

Yes, I have considered that but there are close to 20 tubes in the "bundle" that are leading to this one location and that will make the area around the distribution manifold look somewhat messy.
