SCWD fixing

[zlwags85]

Well, i got one of the SCWD that stopped after a couple of hours use. The warranty was void so i decided to open it up and try to fix it. The glue is still drying so i have not tested it all yet, but it should work. I took 1.1/2 inch PVC and after being sanded a bit it was a super snug fit into the SCWD. Then i went to a coupling and then to a bushing that ended at 1/2 inch female threaded. I can now either skrew it directly to the mag outlet or i can put a 3/4" hosebarb fitting on it.

Im hoping the the PVC will fit tight enough that i dont have to cement it in and can just put a ring of silcone or something around it that could be removed or cut to open it back up easily again. Heres the pics so far. Sorry i dont know how to shrink images....

and the PVC to coupling to bushing that had to be notched out to fit over the 2 radaii peices in the SCWD

Don't bite your nails!


Let us know how it works when you're done. Looks like a good mod!

yea, i get bored in class.....

Well, i let it sit for about 6 hours and pushed the PVC into the SCWD and ran it under a faucet. It switched every 20 seconds or so, the GPH out of my sink is slow Also I think that you could either make it so that the propeller was closer to the inlet or farther away to change how fast it would switch. I tried to get it about the same distance as it was, im guessing its going to take an additional 2 seconds to switch on my mag 3 then it was(was at 8 seconds).

Now the only problem is sealing the area where the PVC meets the SCWD. Like i said i dont really want to use PVC cement to permantly keep it there because it would not be able to open again. there is about an 1/8" gap between the SCWD body and the coupling. Anyone have any good suggestions on what i could fill this with to make it airtight/water tight, or am i going to have to cement the whole thing in. I wasnt sure is silcone would do the trick or not. Suggestions welcomed. thanks

I took a pic of it so you guys can see what I'm talking about.

Here's an idea why don't you use like some super glue which is semi-permanent that way you could tear apart if need be. Of course you will need to use silicone around the outside to keep the water in. Just my 2 cents.

To be completely honest I don't think there's a good way to do it--that's a big gap. Even silicone wouldn't hold permanently.

If I were you I'd rough up the plastic and use a few layers of fiberglass cloth and epoxy. If you ever wanted to take it apart again you'd have to use a dremel.

the PVC pipes are cemented together so the only thing that needs to be closed up still is the pipe which goes inside the SCWD and the SCWD. So far my options seem to be leaning towards just cementing it in and cutting it back open and redoing all the fittings if it ever needs to be opened. Thanks for the suggestions. Anyone else got ideas?

WHAT I DID WAS PUT A 1 1\2 ABS SLIP TO THREADED FITTING THEN I GOT A 1 1\2 ABS DRAIN FITTING AND ATTACHED IT TO A 1 1/2 TO 1 REDUCER...I ALSO ATTACHED 3/4 THREADED TO SLIP FOR THE RETURNS BUT YOU HAVE TO GRIND THEM DOWN FROM THE INSIDE OF THE SQWD...THEN I COVERED THE WHOLE THING IN MARINE EPOXY AND WHEN IT WAS DRY I SANDED IT SMOOTH
