A few Plumbing questions

OK thanks. I will just sit the pump in the return section of the sump so I wouldn't need an inlet tube, and I noticed that some pumps just have a ribbed outlet that you would clamp tubing on.

 

yes they do and if not lowes has all the parts to hook up tubing!!!! i got a 1" threaded to 1" tubing fitting for like $3.00

 

No, 300 gph is fine, but you don't need 1" PVC to do that. Plus, if you want to hard pipe it thats OK too. If you use tubing, you just get a hose barb adapter. You can use 1/2 or 3/4 inch PVC all the way around and have plenty of flow for 300 gph. 1" and 1.5" is huge for that.

 

i was just using that as am example !!

 

I still like the idea of using 1" on the drain, so I don't have to worry about my return flooding the DT before it can drain back down. I guess I'll have to hard pipe it in order to place a ball valve split on the return to regulate flow.

 

yes on the drain i would use 1" at least imo i would use 1-1/4" just in case you ever need to go larger. bigger is always better on drains imo

 

also dont forget to vent your drain line to get better flow and it will not drain as loud

 

What do you mean? Like an air line tubing above water level to release pressure due to siphoning?

 

on your hard pipe drain put a tee in line then out the side put a 90 and some pipe it does not have to be higher than your tank. as long as it is pointed up the only way it would overflow is if your drain got stopped up after the tee.

 

Roger that. How does it help on noise? I also plan on the end of the drain being submerged to help reduce slashing noise. Do you see a problem with flow blockage if the drain is submerged in the sump?

I think I may go with flexible tubing for better flow.
