Client ran out of oil. Locked out. Has Grant eco ext. wall boiler 1.3 mtrs off ground. Tiger loop on wall same height as burner. Tank 4mtrs away on ground. 10mm copper suction line.
I went round. It never restarted via reset button so bled a bit from pump and Ok. Pump was a bit winey and pressure jumping at start but soon settled, I presumed just air clearing via tiger loop. Ran fine. Next morning Lockout.
I returned and reset and noticed air still bubbling through tiger loop on return line. Suspected air getting sucked in through old flexis or isolation valves
I replaced the flexis. Put a clear one on the suction side and removed isolation valves. Redone suspect compression joints (no inserts!! as usual). Bled and all running smooth. Suction clear flexi line full of oil , no air. Great...I though job done.
Boiler off for about 40 min then I restarted and straight away air suddenly appeared in the clear oil flexi and boiler locked out. ?? There is only two elbow compression joints on the run from tiger loop 60cm away to the clear suction hose. I replaced one and the other one awkward access would vent back to tiger loop if drawing in air.
When running no air in clear flexi. When off no air accumulating in clear flexi. Suction pipe has high point at tiger loop and other at flexi so presume any air from a leak would be seen in clear hose or vent back to tiger loop.
Could the tiger loop suck in air at start up when first started. should I be looking at tiger loop for fault.
What are the possible thing that could go wrong with them?
Anyone with an idea how to pressure check pipework with tiger loop?

Anyone know if the tigerloop with clear plastic top is no longer compliant? I was told today from P centre only glass top tigerloop now compliant and of course at the double price...
