i do like that big expensive looking ball-valve you got there.. nice big red handle
as for the weather, were getting fed up with pumping out rainwater from the pond construction site eerytime work is done..
that nice big valve was free from the makers of the poly tank they had 3 from another job good of them , well the filters went in today , pumps over the weekend and uv then im almost there , just need to work out the best way to fix the nettig on the pergola as its a fan shape do i go straight across or do i do each gap one at a time ??
