Ya, like Vaughan said, there are the low point drains (and you should have a little white overflow inbetween
and then the standard drain and overflow that I valved as well.
On your recliners - that was a transitional year when Redwood changed furniture. If you have the older versions, they just don't quite recline all the way and I would toss them. If they do recline all the way you have the newer ones like pictured and they might be worth fixing just to keep it simple. We really like ours.
PS - the newer furniture is Williamsburg Furniture at Williamsburg Furniture Inc.
. They may be able to help as well.
