Splicing power cord on Submersible pump
I installed a Little Giant NK-2 submersible pump into my pond to supply
the water fall. The way the pond is constructed, I had to cut the power cord to run it through a hole in the bottom, and then splice it to power in a junction box. I was careful to seal the junction box. The pump operated fine for many months, but then died. The junction box was filled with water (and possibly oil), and shaking the pump, it was clear that oil had leaked out. Is it likely that the oil leaked out the power cord? Does the plug on the cord provide for part of the seal, and should therefore not be spliced? What sort of pump should I replace it with, given that I will need to cut/splice the power? |

Does the plug on the cord provide for part of the seal, and should therefore not be spliced? Not likely. You need ask an Lic. electrician that question. Where water and electricity meet is no time to take chances of any kind. What sort of pump should I replace it with, given that I will need to cut/splice the power? It's best to do some research and to see what may be best for you situation. Right now most of ours are made by Danner Mfg. They're called Pondmaster Magnetic Drive pumps. They last for years. -- Koi-Lo.... frugal ponding since 1995...

Splicing power cord on Submersible pump
Its highly unlikely your oil came through the cord....Little Gian t
pumps are well known to just up and start leaking......I personally would go with a Danner POnd MAster pump. They are submersible and depending on the model (IIRC MAG 5 and above) thewy can also be used outside thw water and no need to submerge so it may double for a pump for something sometime..The MAG drive series of pumps are oil free and no possibity of leaking. They are virtually bullet proof. Just match your gph on the LG pump and mayabe even bump it up one size.......but pump for pump the mag drives are a better pump all the way around.....If yur pump is relatively new you may inquire with LG as to having it returned and have them replace it. I do not think cutting the cord should have any problems with warranty sa you never really took the pump itself apart.......If they did exchange it for you always ebay iot or keep for a spare for something or other.....I have to back track on something I stated previously.yes oil can be pushed though the cord, if the pump is sucking in water it can pressurize and push water or actually weep / seep water through the cords conductors and insulating material, and with a molded on plug it could keep it from say filling your junction box, it would still displace the oil in the pump with water and die just the same........poor design IMNSHO.

What sort of pump should I replace it with, given that I will need to cut/splice the power? Danner mag drives are the absolute best value in water pumps. You only ever need another brand of water pump if you are doing something usually insane like making a 40 foot waterfall for example (other brand pumps sometimes are capable of doing that but they cost a ton more money and use a lot more electricity which causes more money to be spent for the energy consumption), I got myself a mag-7 and I LOVE IT! I am going to buy some more so I can automate my tanks' topping off like roy also suggested I do, a while ago on another newsgroup. Danner still makes a mean air pump as well (older technology but possibly has more air pressure capability than any other air pump I know of I think, and it's belt driven for easy repairs and the plain fact is that air pump just plain works for even the most demanding applications despite possibly being a little more noisy than a comparable non-belt driven air pump) but it's still a little expensive considering (danner's air pump). Good luck and later! |
