Without ball valves?

[tropic]

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?

Hi which tank maker did u spoke to? Did there say why don't need balong valve?

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.

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.

I roughly got what u mean.

What he say is partially true. But FYI there's a very high end ball valve available out there in ther market. If not wrong per pc cost about 20 over dollars.

Anyway, just to answer to your question.

Ball valve do create headloss for your return pump.

2ndly yes if your piping is run properly u wouldn't need a ball valve in terms of do not place return pump output piping in water will in order when u stop the pump, the water will not be suck into the sump.

What's your peace of mind u refering to?

If u r trying to say if return pump stops of power failure u can use that (ball valve) to prevent water from back flow and overflow your sump, unless your ball valve is electronic. Otherwise it's still the same...

i will go for a ball valve for the return pump... think about what if your pump spoit and you need to change your return pump.. drain all your water in your sump tank?

You are not watching your pump 24/7, some water will be drained back when it shuts down. No need to waste money on check valve though, just ensure your sump is big enough. I assume tank maker will know what to do to the end of your return.

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.

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

Are you referring to check valve to prevent backflow??

Ball valve or check valve are we talking about/?

you are right tank design should not allow a lot of water to flow back in the event of pump fail...

but where you usually connect the pump ? as close to the bottom of the sump right... so if there is no ball valve and when you need to change the pump dont you think that u need to drain off the section of the sump where there is water connected to your pump...

This is just my opinion.

When I need to do some maintenance in the sump, I'd prefer to have minimal water in there for better access to equipment. Too much water due to back flow will result in lots of splashing as I dismantle equipment for cleaning & putting them back. So I'll end up cursing myself for making a mess. So to avoid all that, I'll still go with ball valves on both ends of the piping.

Thanks for the honest opinion.

Hi all, hijack the thread a bit, where to get the 3/4inch check valve?

go to this area

Desker Road Shop Houses, 149 Kitchener Road 208525

there is a hardware shop near to a bus stop... u can find all sort of pvc pipings there ... except some US and JAP brand piping .. best if you can bring along a fitting or pump that you need to join the check valve.
