  For a finite simple graph $G$, the bunkbed graph $G^\pm$ is defined to be the
product graph $G\square K_2$. We will label the two copies of a vertex $v\in
V(G)$ as $v_-$ and $v_+$. The bunkbed conjecture, posed by Kasteleyn, states
that for independent bond percolation on $G^\pm$, percolation from $u_-$ to
$v_-$ is at least as likely as percolation from $u_-$ to $v_+$, for any $u,v\in
V(G)$. Despite the plausibility of this conjecture, so far the problem in full
generality remains open. Recently, Hutchcroft, Nizi\'{c}-Nikolac, and Kent gave
a proof of the conjecture in the $p\uparrow 1$ limit. Here we present a new
proof of the bunkbed conjecture in this limit, working in the more general
setting of allowing different probabilities on different edges of $G^\pm$.
