Return Pump Down n need advise

[violence]

Last night my entire house electricity tripped and managed to narrow down the problem to my return pump.

currently my pump in mounted onto the back wall at the bottom of the tank and is integrated together with with the return pipes thus making it difficult to change/replace. Moreover the brand of the pump Meber (german) is not easy to find.

Anyone with a similar system who had problems with the pump?

Tank is already around 5 years old

Any advise would be appreciated

Thanks, but removal and installation seems quite complicated

If the connection between the pipe and pump is threaded it should be easy to replace. If its been silicone tight, then you may need to have some additional pipes and union in order to solve the problem.

Maybe you can post a closed up pic of the pump and pipe assembly, we may be able to give you better advise.

Is the brand Mebner? If so, the local agent is Mainland Tropical Fish Farm at Pasir Ris Farmway 1.

Slightly closed up picture. not sure how pipes were connected to the pump but i think quite abit of modification done

Tank was done by Wakai marine. Any idea if those guys are still around?

Bro,

The parts circle in red should be the thread union, this is where you can remove the pump from your piping systems.

Next check whether you have ball valves along this line to shut off any water supply to/fro the pump. If you do not have one, then be prepared that when you unscrew the unions, water will be flowing out from the joints and get ready some buckets.

THanks for help and advise bro. Will try to unscrew the unions. Think the hard part will be getting to the screws that are mounting the pump to the wood. Hopefully the holes will still be able to hold the new pump. Worse case have to modify the pipings

There are control valves installed so should be able to shut them off.

Looking at your pic again, I believe the below could be your ball valve. Shut this off to remove the pump.

If you did not use force to remove the screws securing the pump, you should not have any problem re-attaching the pump back into your cabinet.

If you are unsure how to go about attaching the different elbows and unions on your pump, you can bring the old pump to Mainland and get them to do it for you, they do sell PVS pipes as well.

If you intend to do that, you will need to get some aeration in your main and tank while you change you pump and also to wait for the silicone to dry on your pipes.

As you have livestocks in your main tank, you may want to allocate 3 air stones in your tank and another 1 air stones in your sump. During this period, do not feed or on your lights.

THANKS! Thats a great idea.

Currently diverted my skimmer pump in the sump to my chiller which goes back into the tank thus giving some water circulation

Hopefully should be enough

No worries.

Thinking out from the box, if your old pump is beyond servicing, you may want to changed to another pump and get the retailer to do the change for you. You may want to try Eheim pumps, they are known to be very reliable.

Managed to remove the old pump although was left with a rusty screw stuck in the wall. Replaced with the Aquabee 7000.

After removal of the mebner pump, realised that it's not suitable for marine tanks. (No thanks to the guy who sold me the pump together with the tank)

Attached is the picture of the corrosion and realised the following.

1. Why no one else seems to be using this pump for their tank

2. Why my skimmer skims out brownish stuff the last 2 years (always thought was the rawas)

3. Why my rawas has to be replaced regularly.

4. Why only hardy corals can survive in my tank.

Put in poly filter and will do a few water changes as well as was out some rust stuck to the pipes.

Hopefully can get my tank back to full potential soon.

aquabee pumps are good! dont think you got the same issue for the current pump that is so rusty o.o.

all the best ! hoping that everything will turn out as a blessing in disguise.

good luck!

Wow, that's bad.

Mebner pump are manufactured for pond and fountain applications. When you first posted that your tank comes with Mebner pumps, I thought it was fishy that's why asked you to contact Main Land and hinted you to change to Eheim.

But I never thought that the situation is this bad.

Anyway, hope all goes well for you from now on.

Happy reefing

Did consider Eheim, but the 1264 is only 4500l/h. Old pump was giving 8000 so needed something similar.

I understand, anyway Aquabee is just as good. And like Ehiem, the distributor carries spare parts.
