Inflating all tubes at once with a four way valve

[909]

Obviously you would finish each tube individually.

To save time and effort, it would inflate all the tubes at the same time to say 70-90%.

Has anyone done this before.

Really? What have you been smoking !

It's obviously bonkers but the flaw is that one pump only pumps the same volume so splitting it 4 ways wouldn't inflate any quicker. You'd need four separate pumps.

Alternatively, just buy a new self inflating life raft each time?

Do you guys not switch from side to side to inflate evenly.

Yes, inflate bow 70%, port 70%, starboard 70%. Then the same sequence upto 100%.

Its thinking outside the box that helps to develop things, however, how much time do you reckon it will save having a 4 way port? A couple of minutes max maybe. Would it be worth the effort for you?

Yes we inflate evenly, rotating in third or quarter pressures.

Probably not such a daft idea as it sounds as would save time swapping from tube to tube.

I suppose fairly easy to do with a four way splitter/hose mender giving three heads. Downside being having to use adapters without central pin or you’d lose pressure in all chambers when disconnecting.

I think I’d also need two pumps, with one as a regular single head set up for topping off and inflating keel or hp floors etc.

If you're looking for some completely out of the box thinking, how about this guy who inflates his Honwave with a leaf blower? He claims a massive speed up, even accounting for the fact that he still needs to top off with a high pressure pump. I wonder if that speed up would be maintained if he was using a 2 stage pump instead?

Great responses in this thread boyos !

I find myself circling the tubes multiple times trying to inflate as evenly as possible.

I think not doing anything about that wasted effort, is even crazier .

The leaf blower looks interesting and maybe would save a few minutes.

But we use 2 pumps with digital preset pressures (one bought with sib and the other a cheapo off amazon). Set about 3/4 and go all round, and then up to full land pressure, then top up again once in the water if need be is the plan with the air floor.

Being newbies we use the pump up time to unload from the car and check everything, and see what we forgot to take

The boat is inflated before we get our act together to launch and get the bags stuck back in the car, so inflation time really isn’t an issue for us.

Deflating and packing away the beast is a different story, and we already find this is the biggest pain in the arse!

A lot to be said for a trailer set up, even if not actually launching straight from it. Could Just be wheeled on and off to get home, and worry about deflating the thing after (if parking space long term is an issue like we have)

That or I would consider a van, truck or normal box trailer, so we don’t have to be so concerned about how small we have to fold the bugger to fit it in the boot.

I currently use 2 batteries, and 2 pumps.

It cuts the setup time in half.

The Zodiac I/C valves note 3-4 psig as normal tube pressure.



1) Do you maintain this pressure with a pressure gauge or use the "seems about ok" pressure test?



2) How often are you re-pressurizing/ topping off your tube pressure?

You may not get a response from 909, think he's doing a photo shoot for Grinder

Does it say 3 - 4 psi or does it say 3.4 psi?

Personally I'd always use a digital pressure gauge and preferably an electric pump with a digital gauge.

I always check the pressure about 15 mins after I've launched, especially when it's a hot day.

[DSR-550SRMN]

Very good point....


The illustration on the I/C valve is 3,40 PSI. I looks like a "coma" not a "period". I understand that as "between 3 and 4 psi". Yes?

[Steve509926]

That is definitely 3.4 PSI, not 3 - 4.

You could go this way rapid inflation

Thank you!
