susie53 -- Yes, and the receipts from the grocery store are overly lengthy. Are you supposed to think you got MORE for your money because the receipt is a yard long? If I'd kept all the Citi American Express card offers we've gotten this winter I could paper the back hall. Stop already! Since his father's death in the late 1940's my DH has received a government check for $1.89 every month. DH is beneficiary of an insurance policy his father took out when he served in WWI. It took us years to get them to issue just an annual check. I wonder how many other people are getting checks are worth less than they cost to issue and mail. (How many government employees spend their days overseeing this waste?)

OK bro, You know I hold you with the highest respect but lets see how much fun you would have vacuuming with that light a pump. Your probably right in that filtering power is OK but to vacuum, no way. Been there, done that, won't go back. The 3/4 HP is in my opinion, the right choice. It reduces his power consumption and provides enough suction for vacuuming or running a floor sweep. Sctt Scott

"Standard garden arbor 84 inches high, 56 wide and 26 deep." That is simply your size, it is not a standard size. How will you apply the stain? Roller, brush, or sprayer? Sprayer takes more material. We are trying to tell you there is no answer possible with the information you provided. Buy a gallon and see what happens.

If you build a loop and don't run a pump, it does usually take longer for the water to get hot. Much of that is because the loop is larger diameter - but that certainly depends on your setup now. It is fairly common to use a 3/4 pipe for a distance and then branch 1/2 off to fixtures. When you design a loop, it is always done this way. So it depends a lot on what you have now. You can homerun a 1/2 in pipe to speed things up without a pump. A 3/4 inch pipe carries just about double the water 1/2 does - which means double the time. Your 2 minutes could become 1 minute if it is currently off a 3/4 main and you homerun it with 1/2 inch. Can be even better if you remove elbows/tees. And even better if the route is less direct because it comes off a main. And then copper does not equal Pex. Copper steals a bit of the heat and doesn't flow the same. Does your tankless say it is ok to use with a pump? In the past, it was not recommended to run a pump with tankless but that has changed. The overly frequent cycles is not something the tankless were designed or warranted for. I know that there certainly are ones that are designed for a pump nowadays but not sure all of them are. Could mean a warranty denial if it says to not use with a pump. I have to think extra wear and perhaps more maintenance is a consequence of having a pump. The tankless will fire say every 15-20 minutes when the pump is running. I had a monitor on a pump and the pump ran 7 minutes in every 20 to keep the loop warm. Then the heater would run once every 20 minutes to reheat the tank for about 5 minutes. Length and insulation characteristics would change this of course.
