Pumping from the lake.

Similar pumps are often used on fishing docks to provide running water to fish cleaning stations by suspending them in the water. The 1/3 hp pump says it has a maximimum head of 33.5 ft, so i would think it would work since you are lifting the water only 20 ft

I hope that you know that lake water is not really "clean." I would never use lake water to wash dishes unless it is sanitized somehow. Either boil, run it through a microb filter, or use bleach. Try sitting a 5 gallon bucket of lake water in a nice shady spot for a couple of days and then smell it, you may change your mind. Remember that a lake is is the outhouse for fish, animals, birds, and humans.

Where I live the lake fish are all on birth control due to the ladies at the beach relieving themselves in the water. There is a number of pollutants in that water, and people often get sick after swimming, ear infections are common. Some of the residue will not disappear on dried dishes, it will just be dry and you will eat it. gross.
There are filters that will clean it, but they are slow-drip and will be expensive for washing dishes.
20 feet elevation gain will be slow but doable with the right pump. The distance is not going to matter as much.

If this is for a semi-permanent location, or your own property then you can make a filter with a 55 gallon drum, sand, rocks and other things. Do an internet search and it will be easy to find. This could provide water at a fast enough rate. I would spare your RV tank and get an external holding tank if possible, but thats up to u.

Standard practice for scouts, missionaries in many developing countries, etc. where the water supply is of questionable or poor quality is to wash dishes in whatever water is available but rinse in boiling hot water. Tongs and mesh bags help a lot with the rinsing assuming you aren't keen on scalded fingers.

would definitely use a jet pump that way you could have water on demand and forego the use of your tank. Lake water is not chlorinated so it will go skunky in your tank within a few days in the heat of summer.

OP Here

I do plan to pour some bleach in the tank when I fill it and it will be drained each winter.

As far as the idea of keeping it off the bottom, I know I need to. The bottom is muddy and I'd rather not suck the mud in.

Power will be supplied by a generator.

The 5gal bucket w rocks and strainer tied on is an easy way to keep the strainer off the mud no matter which pump you choose.

There are other similar pumps for a few $$ less than Honda.

Why would I go gas when I already am running a generator that can easily take the load. The tank would last all season.

Don’t over-think it, get a $uo sump pump from CDN Tire / Home Hardware Princess Auto. Put a rock or concrete block on the bottom with a rope tied to it, empty bleach or laundry detergent bottle as a float, pump hanging just below the float. Garden hose for the output.

Easy peasy, citronella squeezey. (Citronella to keep the skeeters away.)

That's the plan..... Just don't want to buy it all and find out it won't work.

Did you check the reviews on the pumps you listed in the OP?

Versatility and not mixing electricity w water are 2 other reasons.

It's an option; perhaps someone other the OP might find more suited their application if they happen to stumble upon this thread in the future.
