Are the bricks to prevent rusting? There has been water in the
basement on several occasions but it only made it to the furnace when
the furnace itself was leaking,

If you had water before, you'll have water again. Maybe next week or
next year or next decade. The bricks buy you a few inches of time. The
also promote good air circulation around it to prevent rusting. In some
cases, it makes it higher, thus easier to service.

But a "few" inches means a LOT of safety. Assume 1,800 sq ft of basement and
6" of support. That's 900 cubic feet of water before the flood hits the
furnace gunwales. That 900 cubic feet is almost 7,000 gallons!

Usual faucet flow is in the neighborhood of 0.5 gallons/minute. For the
above calculations, an open faucet in the basement would take 14,000 minutes
(or almost ten days) before the water level reached the furnace.



if my faucet was that slow, i'd kill myself. I can fill a five gallon
bucket in about 30 seconds with mine.
