The Physics of Water Pumping

-keep heat pack on tube entire time
- last 15 mins at maximum tolerable pressure
-exit tube and Firegoat Roll to evenly disperse any fluid build up

I can get an 1” expansion normally. I can get a little over an inch if I can take C4 preworkout supplement before pumping. I don’t always do that because I can’t take that stuff if I happen to be pumping at night before bed.
If I have time, I edge for as long as possible. Not sure if it helps but it’s fun to play with that monster out of the tube! :)

I have a max EG of 5.5 but measure an average 6.5 out of the pump. That stays for a little less than an hour then slowly goes away over the next 2 or 3 hours. I do not know my girth gains yet because I am trying not to measure for a while in hopes of being pleasantly surprised one day.

Also, as it is a bathmate pump. I’ve no clue what the pressure actually is. I use markers on the tube to gauge LUV.

I used my Bathmate in the same way as you EyesOnSize , with the difference that I only used it in a hot bath.

I can tell you that now I have my vacuum pump set up for water pumping, to get the same pull as the Bathmate, I need to pump up to 10-12 Hg/in!!! No wonder it’s not advisable to pump for longer than 20 minutes with it.

My first inch of gains was achieved with a similar approach in time and intensity. I bought a cheap vacuum pump that used a plunger to create the vacuum, the plunger didn’t work so I sealed up the hole and attached a flexible plastic tube to the side of the cylinder and used my lungs to create the vacuum and my tongue to maintain it.
I thought that if my tongue could survive the low pressure then my dick would be safe. Surprisingly I managed to pull some serious vacuums and ended up with blood spotting and donuts. My sessions would last 20-30 minutes and I would always enter the tube with a full erection and suck the air out until I could feel a stretch. I would try to remain at the longest length I could inside the tube and when it went below a certain point, I’d rework the erection. Usually this would happen 4-5 times per session, more if there was a vacuum leak. Anyway, it was an exciting time and gains came quickly, I achieved an inch in 1 year without extending the duration of each pumping session.

When I started using the Bathmate, it reminded me of that time with the advantages of constant heat and no requirement to enter the tube erect.

I enter erect as well. I have an air pump that I’m thinking of converting to water because the tube is wider and will accommodate my girth better. The accordion plunger at the base of my bathmate gets packed too quickly and I get rings around my base shaft that are unsightly and leaves a weird darkening pattern.

I tried to follow the size chart when purchasing but never expected over an 1” of expansion. Thought it would be a year or two before I had to upgrade but it looks like that’s the route I’ll have to take sooner that expected. I do count myself lucky in that respect. I know a ton of guys would love to have that “problem”.

Some guys cringe at the oral vaccuum method but I don’t care at all. It’s my dick, not some other dude’s dickwater. If I convert my old air tube, that’s the method I’ll be using.

So after reading the info on this post. I have a question. If there is pressure with in the pump and penis. Is this same pressure that a scuba diver gets while diving deeper then 30ft?If so does that mean you can get decompression sickness (Bends ) from pumping at high pressures with in the water pump? Or is there only risk of this if pump is left on to long?I’m new to this though I have used water pump ,I have stopped after reading about decompression sickness because I was unsure about this.

I know this might not be the right place to ask this question ,but I have been doing PE for more than 5 years (I’ve no reply so I can’t start new thread) and just recently found information about Mr. Fantastic water pump and I’m really interested.

Am I still able to get this device? I saw his last activity here since mid 2016 so I’m not really sure if he is still active in PE.

He hasn’t been around for a while unfortunetly and the last few guys who ordered had problems, shame as it is a great device.
You could try emailing him via his website.

Yeah, I’ve tried contacting him with his contact in his website, email, Skype, but no luck yet.

Desperately want this one :(

I’m not sure if I’m the only person experiencing this. I’m not going to call it a problem but while using the bath mate my penis feels like its going to explode. Of course it doesn’t and once I take the bath mate off my penis looks the same just a lot bigger and it’s not deformed at all.

Mr Fantastic

Any luck getting in touch with Mr F. I am really interested in this pump as well. Did you find alternative, if not?

Thanks

I manage to use them without much hassle and spill infront of my PC.
I prefer penomet to bathmate as it seems to produce lesser discoloration. Both are totally overpriced though.

Why do you think that the penomet produces less discoloration?

Man this pumping seems like so much work just to find what works and what not

I read the thread about Bathmate’s and no pressure gauge and other pumping issues so I have tied to put this together.

My size is 7” BPEL x 5 1/8 EG. This is about 14. 26” volume. I don’t know what the volume is in the inside of a Bathmate.

I read on the pumping forum that somebody uses an air pump and says suction of the tube by mouth and pipe equates to about 3-4hg. I bought a cylinder and squeeze pumping ball, took off the ball and tried expansion of the penis by mouth suction with tubing and it worked.

The volume of cylinder is 26.5”, the cylinder being 2 1/8”dia x 7 1/2 long. I took the volume of the cylinder (26.5”) less my volume (14.25”) approx, worked out that if I fill the cylinder with warm water to 3 7/8” level, insert the penis and suck on the pipe until all the air is out then if I expand to my 7” x 5 1/8” the hg is about 3-4hg. If I then expand to the same size in the Bathmate then that pressure should be 3-4hg.
I think it may have been Sparkyx who said about using a tube and sucking the air out by mouth.

Do you think this theory is correct?

I tested how much negative pressure I could pull by sucking on the tube of my hand pump, easily reached 12”hg on the gauge.
Keep in mind though the internal diameter of the tube/hose you use will affect how much you can pull, smaller size hose makes it easier to reach high levels.

I know that it is an issue that the Bathmate has no gauge but if the penis size is the same size in a tube which is pressurised by mouth and it reaches the same size in the Bathmate would the pressure be the same using water? If the ordinary tube had a gauge then this would be more accurate.

Would this be an indication of pressure or would the internal size of the tube have a different effect? I don’t know the internal volume of the Bathmate has the rubber base would vary volume.
