Thanks for the honest opinion.

Ah...I see where you getting at. Thanks.

Ball valve or check valve are we talking about/?

Are you referring to check valve to prevent backflow??

Ball valve and check valve is the same//? i think we are talkiing about ball valves here to regulate or switch off flow.

if return pump spoilt there will be some water which will flow back down into sump and stop right? so the water will still stop , then you can change the pump. the tank design should not allow the return pipe to backflow alot of water in the event the pump fails.

Negotiable .

Btw, from some online information that I gather there are some cases where the ball valves not fitted for downflow as the need the flow to be unrestricted as possible. Ball valves are fitted only for those return that are T-off . I believe most of us will have ball valves fitted. Maybe not a norm to go without but for peace of mind rather not having it at all.

4 pcs of PP 4"x8" sold. rest available.

Hi. Was told that valves may leak over period of time but if customer insist they will still include. it was a suggestion by them to go Without valves.

Anyone has their tank plumb up without ball valves for both the overflow downpipes and return pipe? for maintenance issues it could be useful but spoke to one of the tankmaker , does not encourage having ball valves for return and overflow. If the water flow are calculated porperly, there shouldn't be any problem when pump stops. Anyone has any say or view on this?

SUMP tank going for $80 .take and go.pm me if interested.

Yes. Used. Rotate washed using powerful spraybar and dried. It's look clean enough for next use. I try put up some pics tonight.

Until then I got something similar hope it works as well. Not really threaded.

Thanks for all suggestions. Hard to find with two outlet that are both threaded.mostly are single outlet smooth and the other threaded. I am fixing a powerful spraybar so smooth surface I cant use to secure. Will slip n drop off.
