    Thanks James - The aux ground path (as set out in the fenwal kit) i had put in earlier. So i reckon it must have been these little bindi eyes swirling around in the mixer. Have you ever heard of such a thing? Or maybe she,s a heater that needed a bit of tlc on every level to come back to sync...

    Thanks guys, your point on different index units is something Johno (the gas guy ) picked up on. I was showing him he manual the former tech down loaded and he noted that the values where all imperial ie. Wc and inches and no AS/NZS gas accreditations. He said we measure everything in Kpa . and...

    Back again and still no wiser. So gas fitter came today and checked the regulators, propane tank and 1 stage regulator all good. 2nd stage regulator for the heater ( exclusively) was all good too . He set up his nanometer to test inlet pressure on the heater as set out in the manual and it was...

    Movement of Pavers - New Travertine Paver Installation

    Reactive soils can move your pavers. If your sand, scallops or grade substrate is/was not packed hard or thick enough and you on a trap or clay, then as the ground absorbes water or dries out the clay swells or contracts. Up and down. Over time this may become a wave or just soft spots. Good...

    Need help with existing pool deck resurfacing.

    I’m not a pool builder but in commercial and residential. I would be asking , what is causing the cracking? Is the substrate solid or fixable for refit? You need to fix any issue in the structure before you dress it up. I reckon money spent on the structural bones will save you the griefof...

    "Thinking Hat" on now , - if the pentair guy said he adjusted the gas he must have played with (2nd stage regulator) ,the inlet regulator yes? i read in the manual and it seems to imply that everything is factory set in the manifold/regulator (no adjustment?) and as you pointed out James it...

    G'Morning James, The tank is a 2500 litre tank about 20 metres away, and the regulator is in one of the pics, nothing has changed on the setup since 2013 so i guess time has wearied it. I somewhat expected the response from pentair/plumber guy i got this morning as he said he was "wearing his...

    Wow thanks James that’s so obvious I ve even read that in the manual I think. I know the pentair guy is a plumber who got the job because we live a bit outback , but that’s no reason to miss that. He charges like a wounded bull as well so we got no change out of 850$. Yep he’s got all the gear...
