Man, I read Pumping 101 back in Nov when I first joined T’s Place, but guess I missed a lot on the first read. I just read this whole thread again and you guys have peeked my interest on water pumping, I think it may be the only form of PE I haven’t tried yet. myeight’s comment above has given me an idea. Before I go out and buy a water compatible pump, let me ask this question to the group.
Once I realized the Doc Johnston hand pump (Sold in sex stores as the Doc Joel Pump), was basically a piece of s—t that falls apart almost every time you use it, I bought a Kaplan hand pump and have really good luck with it, mostly in girth gains. I still have the old Johnston pump. I guess I’ve just been holding onto it for a backup or for parts, mostly the gauge, in case the gauge on the Kaplan pump got broken, or in case I someday ordered the electric Kaplan pump which is a lot cheaper if ordered without the gauge, but I have recently found the threading is different. So now that I don’t really care if I damage the old pump, I was thinking of trying it underwater in the hot tub. I suppose the water will destroy the gauge but since it will not fit the Kaplan pumps anyway, is there any reason I couldn’t just take the whole rig out to the hot tub and pump away?
Should I try to remove the gauge? I could unscrew it, but it will leave a hole to suck air, or water. I guess I could find a way to close the hole, but might just be easier to just leave the gauge on, or just let the hole suck water until pressure is acheived then pop the hose off. I would be pumping blind as far as pressure, but like Avocet said after a while you kind of get a feel for the correct pressure, and know when it is too much unless the feel for pumping water is different than pumping air. Or perhaps the gauge that is on the cheap pump now will show pressure in hg underwater? I think everything is plastic anyway. However, I know that water is denser than air, so I’m not sure the readings would be accurate, probably safer to just go by feel. Has anyone tried this? Would appreciate any advice on this idea before I perhaps blow my dick to smitherines.
Thanks
