I use them and they seem to work fine. I guess with the poppin version I don't really walk them, I just work them in the holes and around other Bassy looking cover. I don't work them real fast. My guess is you would probably want to use the standard style for walking them.
Cret what versions did you test for walking, the standard styles or the poppin versions?
Looked them up.
Personally they seem underpowered but it will depend on how much water you need to remove when you finally need that pump. The water powered pumps performance is based on water pressure. If you have 60+ psi then you can get 500-900 gpm and it looks like you will use 1 gallon of tap water for every 2 you pump out of the pit. For comparison I generally use 3/4 horse pumps at a minimum for the pumps which gives you something north of 3000 gph.
I'm not real sure if code and insurance even allow them so check first. If you have a small house and if the sump doesn't get used much it might be an option.
Never saw a water driven pump. The ones I use and know if are the battery backup kind. They are sold at all if the big box stores and are around $300 I believe. They run off of an automotive type battery that has a trickle charger attached to it to maintain the charge. You have as much backup power as your battery has capacity and then that pump is dead as well so it's a short term solution.having a generator is very helpful as part of the backup plan.
I missed one last night. Shot a 3D archery shoot yesterday and did really well. From there straight to my blind for an evening hunt. Big tom came in to 32 yards. I ranged him, dialed in my sight and slid one just passed him. That's as far as I've ever shot with my bow but was feeling pretty confident after shooting all day. Oh well.
Sitting in another spot right now and as of 6:30 have not yet heard a peep. Can't sit long today, dang work always getting in the way of my fun.
