I'd like to be able to use protect mode with my leakshield but I have not has sucess.

I am able to use the monitor mode the pumping is 7 ± 5 s/day, in the last 90 day but was not much difference over the last year, there was something like 1 % loss in fill level over the year.


There was a sugestion that the tubes were pulling off at lower pressures so I opened all the fittings and did them and put the fittings down all the way, this did not make any difference.


There was a sugestion that there could be a bad rotary fitting so I changed the one I had for a new setup and it has not made a difference.

My loop is

D5 Next-fitting-EDMP-fitting-block-fitting-EDMP-fitting-HF Next-fitting-EDMP-fitting-Rad-Tempsensor-fitting-EDMP-fitting-rotaryTfitting(rotary-drain)->

My hose is 10/16 mm so should be acceptable

Its quite simple so I am at a loss what to other than to switch over to hardline tubing as the EDMP does not seem to want to work.

Anymore sugestions?

Yes, sorry typo EPDM.

Since there was comment that they could be pulling off, I took the fitting appart to see if the tube was properly on to the barb. When I initally tightened them I didn't get the gap between the clamp and fitting to 0, as the pressure drop when testing the leaks was fine, after the inspection I did them more.

I have the apaptive pressure on.

When pressure is 250 to 300 mbar then the pressure leak rate is ~8 mbar/min when the pressure is 50 to 100 mbar then the pressure leak rate is < 2 mbar/min.

Yes, I have to turn off the pressure leak detection as there is a spike in the leakage indicator of 300 mL/h and the alarm goes off, I just have the one for the fill level, this one doesn't go off as the loop does not leak water at an obervabale rate.

As Speedy said it seems possiable to make it work, I just don't know how.
