Gravity was a slow affair with run off very slow.
1st time using a BM style pump, run off was good and a very clear wort achieved.
2nd time using a BM style pump, the whole system got blocked up and I lost a lot of wort.
Today using the spent hops from the 2nd brew, I tried again the BM pump & also a chugger pump both test failed / blocked after several minutes.
So the final straw was to stretch the spring a little to avoid blockages, this has cured the problem with no blockages, might have to get another spring if using pellets in the future.
Original spring in boiler = 1.5 springs required, stretched spring in boiler = 0.75 springs required.
