2 bilge questions

[Ericfox]

yeah.. I know they say those attwoods dont airlock as bad... it would be nice to figure out a way to fix this problem with the rules though... plus the rule's fit in that nice little bracket...

 

[Mike W]

yeah.. I know... I just want my bilge to work better in case I need it for some reason... plus I'm bored waiting to ride and this weekend looks like azz...

I hate it for you guys up north. Be patient, it warms up by June up there right?:biggrin:

If I could warrant a move just because my obsession with jetskis I would do it in a second... unfortunately I have other priorities.... damn... stupid other priorities... I hate winter with a passion though, so who knows... maybe someday...

I just emailed Rule... I told them I want to talk to someone about this subject... I am really curious to what they say...

 

[Ericfox]

IF anyone is really interested in air lock and what causes it - you can skim through this:

The good stuff is around the 3 or 4th paragraph in the Description section #2.... but the whole thing is interesting... but long winded since its patent BS....

The solution seems to me like drilling a small hole in the pump itself- in the area right around the little impeller- releasing the "air pocket" around the impeller and allowing the pump to reprime itself without turning it off and on...

I will see what Rule has to say if they ever get back to me...

Just talked to the tech guy at Rule...

He said you cannot have ANY dips in the line... so if you put the bilge on the right side below the coupler and then run your bilge line below the intermediate shaft and then up to a fitting- it is going to air lock because you will most likely have a dip (or really close to one) going under the shaft.... he said the more vertical you can make the line immediately after the pump the better... and keep it going as vertical as possible the whole way

The solution would be to just make sure your hose ALWAYS is going up and there are no dips anywhere including loops... and no check valves installed anywhere...

I think I can get it going up all the time and still use that bracket, but if I cant- then I will just glue it to the bottom

my never airlocks

the only thing mine does is once it has about 1.2 inch in the hull it cant suck anymore up so it goes chchchchchchhc and then you turn off and a lil more water comes out. my still leave about a 1/2 inch in the bilge looking near the tank and cases. i run the line strait and then make it run on top of the elec. box then out my out is a little lower than where the electrical box is to help with filling the hole when normal ridding beaching and ect.

on occasion when i am ridding after a sub or somthing where i know i have water to bilge out, if i turn it on and nothing then i usualy go off and then back on and it gets it or it doesnt and water didnt enter or need to be bilged. i have a thumb on off switch by the start stop switch so its easy to on off.

by the way is it bad to ride with it constantly on or would that be bad. like running a garbage disposal with no water.

Check this out... I sent this to the tech guys at Rule to ask them how we should run our lines... they said the 1st and last options will not work well... the first option would prob. result in airlock according to them...
(which is your chchchchchch sound)... he said to do the 2nd option and that would prob solve our problems... I will be trying it this weekend... if not sooner...

Here are his exact replies:

1st reply:Hi Eric:Thanks for the note and sorry to hear that you are having problems with our pump. Airlocking occurs when the discharge line goes up and down
like a "W". The line needs to run continously up and out of the boat.
Airlocks happen when there are dips. Dips cause water to get trapped.
The trapped water prevents air from escaping. The trapped air, in turn,
can make it difficult for the discharged water to get through. The pump
turns on, no water gets pumped out

2nd replyin response to the pic)The second solution is the best. You do not want loops in the line. With
centrifugal bilge pumps there is no way to prevent back flow,
unfortunately. Keep the discharge line as short as possible thus back
flow will be as little as possible.

so my way works and has always worked its that the thing doesnt get all the water out. when it gets all it can it goes chchchchhc.
and hey how is my coupler spacing.

 

[Ericfox]

your coupler spacing is fine... and I didnt write the guy at Rule about getting all your water out... I wrote him about getting your water out and not having your pump airlock like yours does...

 

[Mike W]

I have mine setup like the first illustration. I only run the pump when I need it though.

 

[crammit442]

I'm not sure what the big deal is. My pump will occasionally air lock, but with a good hood and one way/scupper I almost never need it anyway. I run the 1100 rule and haven't experienced any real problems. If you suspect it's airlocked when riding just flip it on/off and the problem is solved. I know people leave their pumps running the whole time they ride, but I've never really understood why unless it's to keep from having to buy a good quality handlebar switch that's easy to turn on while riding.

 

[restosud]

if this was a computer,the tech guy would tell you it's a software issue and the software guy would tell you it's a hardware problem.
the rule tech is full of b.s.i've ran hose every which way and they still airlock.
see what you started shonuff?

 

[vitalikol]

I conected my Rule to original bilge. Just disconect OEM plastic bilge and hook up your electric bilge pump to OEM bilge hose.
Worked fine and no extra hose
