how are you guys pumping water out the bottom of your reservoirs?

mojave im glad you posted i ran into an issue today with my danner pump. i was gonna wait till tomorrow and call the company but screw it. theres 2 connections for the danner pump one where is sucks the water and one to push in out. i found out today that the threads on the pump are not pipe threads. this means i cant use a garden hose or pvc to connect to it. the threads are a little smaller on the pump and it didnt come with any adapters. i tried to screw in some pvc but it wont go all the way in plus its stripping the threads. do you or anyone know some type of adapters or something i can buy to make this work? im trying to use a 3/4" garden hose or a 3/4" vinyl tubing

good idea Crusader Rabbit im still figuring out if im gonna seal it or what but i gotta get this pump figured out first. nothing at home depot fits into the connections the guy in plumming didnt even know what kind of pump i had. he said maybe i should go to a fish store to see if i can find something that screws in to make this work. i dont understand why the pump didnt come with any adapters. now i gotta figure out what the hell to do

heres a pic

pvc and garden hoses are not meant to screw into this

here is an idea that may or may not work for you. you already cut a hole in the bottom of your res. put a bulk head fitting in it to seal it up, after the bulk head fitting put an open/close ball valve on. attach a hose and run it to your drain. as long as your res is higher than your drain the water will drain out and you only use gravity no pumps.

this option is a little different that how you explained you wanted to do things but its also worth a thought. get an external pump hook it up really close to your res and then run the hose to the tub.

like already stated the problem your going to run into is having the pump in a dry location and trying to pull water from a res towards the pump.

Inlet: accepts 1" MIPT threaded fittings
Outlet: accepts 1" FIPT threaded fittings

The pump description says that it should accept standard threaded pipe. This is very odd. Sometimes the taper of different fittings don't match well and an insert won't want to go in far enough. Did the threads seem to match at first and then it bound up or did they never seem right?

its kind of weird because at first, before i asked for help at home depot i tried to screw in some pvc pieces and i thought to myself why are these so hard to screw on and they wont screw all the way in. after that i asked the guy in the plumming department a question and he looked at the pump for 2 seconds and said those arent pipe threads. he didnt even have to try and screw anything on he just looked at it and knew.

i think i figured this out though. yesterday i called danner directly and they told me i need to buy these adapters made by spears or lasco. there called barbed tube fittings

and heres the elbow i bought to suck the water out real close to the floor of the res
http://www.mscdirect.com/product/06414445?rItem=06414445

it makes perfect sense cause these are the same type of adapters that came with every other submersible pump ive ever bought i just dont know why the danner came with none. hopefully these work i havent received them yet. the only thing is i havent found any barbed adapters that allow you to attach a garden hose it seems there mainly meant for vinyl tubing. its not that big of a deal though cause im gonna seal the bottom of the res back up now that i found a way to pump all the water out of the res with the pump directly inside. at least i can still use the garden hose to fill the res

thanks poo-hand but since i found that elbow im just gonna seal the hole back up

The Pondmaster pump that you linked to is supposed to have 1" standard national pipe thread inlet and outlet. The two barbed fittings you linked to are standard 3/4" national pipe threads.

The fittings you tried at Home Depot would have been national pipe thread. When you looked at the threads on the pump to compare with the pvc fittings, could you see a difference? Were the pump's threads finer, i.e. more closely spaced? If you found a fitting with identical threads to the pump outlet, it should be the right size and threads to screw into the inlet.

With PVC a thin wrap of teflon tape can prevent the plastic on plastic contact from seizing when it gets tight. But the threads still have to mesh properly to begin with. You really have to be careful and feel the threads engage when you start. If any parts are softer plastic it's very easy to cross thread.

Home Depot should have the barbed fittings you are looking at. Look for a bank of drawers full of fittings next to their tubing selection. You can also use a PVC threaded "street elbow" for the inlet. If it doesn't reach down far enough you can screw in a short PVC pipe nipple to get the proper length, or with the barb fitting slip a short piece of tubing onto the barb.

To attach a garden hose you'd need some kind of reducer to step down from the 1" outlet to the 3/4" or 5/8' or 1/2" that the hose is. If you cut a hose you could stick it onto the right size barb. But if the barb assembly is screwed onto the pump using the standard national pipe threads then you should be able to screw on a PVC reducer fitting with 1" female pipe threads. Get a reducer (sometimes called bushing) fitting with 1" FPT on one side and 3/4" FPT on the other. Then screw in a short PVC 3/4" threaded nipple. Onto this screw on a brass or PVC 3/4" male hose end ( 3/4" FPT - 3/4" MHT ). Or get a PVC 1' FPT - 3/4" female slip fit reducer. Then glue in a short length of 3/4" PVC pipe and onto this stub glue a PVC 3/4" male hose end. If you're real lucky maybe you can find a 1" FPT - 3/4" MPT reducer. But all of this is contingent on you being able to thread something onto the 1' MPT outlet that your pump is supposed to have.

If your pump really has a 1" outlet then you will be reducing it's capacity by attaching a standard 5/8" or 3/4" garden hose. But even with your 100 gallon reservoir, how often do you drain the thing when it's full anyway? Never?

You can tell the guy at Home Depot that you're using the pump to drain a big aquarium or some other kind of tank or pool or pond.


If you have one of Home Depot's RIGID shop vacs, this is an interesting looking item...

I have many danner pumps and the fittings at home depot work perfectly. The fittings are tappered and not supposed to screw all the way in. You use teflon tape to make the seal. This is another picture of both fittings:


Those are the pieces you buy and then you can hook up another piece to use a hose or whatever else. Its extremely simple.

theres no need to go back to home depot now cause i already ordered every adapter i need online. maybe the guy i talked too didnt know but i asked him if there was anything in the whole store thats meant to screw on and he said no. i even checked on grainger's online site to see if the adapters were available at one of there local stores and it said out of stock

tell you the truth id rather use an adapter thats meant to screw into this pump. i dont really wanna strip the threads and force something on with teflon tape. thanks for tryin to help il let you all know how these barbed adapters work out tomorrow or tues

The adapters you linked to were 3/4" NPT. The pump you linked to takes 1" NPT fittings. The photos that Snype posted are 1" NPT -3/4" NPT reducers which get you down to garden hose size.

no the pump takes 3/4" pipe fittings not 1". the thread is just different but the size matches

Think it came with the standard eco plus pump fittings set. They include a variety. All my stuff is mixed together in a big b ucket so I cant be certain what came with what. You might wanna check their site...
Im sure greners isnt the cheapest, but it was the easiest way for me to link

Actually it says 1" fittings included. Im using 1/2" though. Not sure if that came with another pump. But eco usually includes a bag of fittings and adaptors.

it gotta do 3/4" i dont think the'l be a problem. thanks for the info coconutz if i run into a problem with these barbed fittings on my danner pump im gonna give that a try. i think im all set though

just wanted to let you guys know i just received the barbed tube fittings and they fit the pump perfectly. no tape needed or anything there perfectly air tight and screw all the way in. glad i found this out im gonna pickup a 3/4" hose and drain the res that way. also i sealed the hole in the res using epoxy and a sheet of this plexy glass that i got at home depot. it looks to be sealed perfectly hopefully there will be no leaks when i fill the res today. thanks for all the help guys
