I've tried searching but couldn't find the answers I need.
We just bought a home in TV. We're not retired yet. But we plan on doing so next fall.

Until then we'll be coming down on and off for a week at a time when we can use vacation time.
I've seen where people say to tape over drains to keep bugs out, and to put saran wrap over the toilets to keep the water from evaporating. just wondering if this is good advice?
Also, what temp should I keep the house at in the summer?
Any other tips or advice is much appreciated.

Thanks in advance
