I am looking into the possibility of putting one maybe two large water butts on my garage's flat roof to supply water for a garden hose, car washing with a Karcher pressure washer and supplying the garage sink with water.
Can anyone advise if this is feasible? and if so any pitfalls or problems with this idea that I cannot see yet.
Will the garage roof be strong enough to cope with the weigh of the butts? the roof has 7" x 2" joists at 24" centres and is covered with 3/4 tongue and groove flooring.
thanks
John
