Re: Pump for cross-flow
- Thanks again.
I was also suspicious about the gph figures, but the problem I've been facing is that all the on-line info for the various stores I have access to list only that figure. To get anything else, I have to try to find the same item somewhere else (e.g. a US distributor). I've not been able to go and check these things on-site, but will be able to tomorrow.
Now I have something to go on!

- Or you can just look around,. Most people have them all over their homes. All you need is a transformer. Like the ones that are used to plug in cordless phones. Or Those Picture frames that have digital pictures. or what ever..Look on the taggs of the pump to see what the Amps are then Find a transformer that suits.. IF you don't have one at home Ebay, Or Radio shack has all you need any size you want..
Wire it up and plug it in.. Of course this is just my 2 cents worth. I sure there is other ways to handle this issue. but this one would only take a few minutes to fix;./ HTH Nameless "I forgot My Name"

You can get transformers from 110 to 12V, I saw one just the other day
while I was looking for something else and thought, "interesting, but
don't need that..." :)
