I have a grunfos MQ3-45 that's been going strong for 8 years now. Researching this scala2 vs the DAB mini box 3, what's your opinion on these 2 pumps? I've been seeing a lot of bad reviews on the scala2.
Hi. My 12 year old MQ3-45 pump is used to pump 1,000 gallons every 5 to 7 days. The pressure gauge is pressuring to about 70psi, stops like it should, and then leaks down over about 3 to 4 minutes to about 30psi, and kicks on to repressure. If there are no leaks anywhere, could this failure be the "internal non-return valve?" I only have one pressure gauge on the pump, and I do not have a pressure tank.
If it's a sealed system, it would not be capable of loosing pressure. It wouldn't matter what possible problem a pump had. If the pump exploded internally, the system would still hold the pressure until it was released, either through a valve or a leak.
Was looking into getting a whole house pressure pump and was suggested the Scala 1. How do I know which is best for my house? Also, does it work automatically whenever I want to water my lawn or take a shower?
So this pump is a booster not a stand alone pump system. There are different versions for more Gpm or head pressure. Yes it's automatic and works by detection of flow and psi drop to help maintain given psi settings.
Something with the use case for heatpump water supply caused it to fail prematurely. It was under warranty through my supplier and she didn't have to buy a new one.
Well it's very small HP and has variable speed so one of the most efficient pumps I would say. Pumps In general don't use much power anyway because they are only run for around a hour at most per day. That being for a typical water supply case for a household and not heat pump supply.
@ClearWaterPumpWell what about in my case? The house has 4 people, 2 of which are small children and 3 full baths. Our washer and dishwasher run all day, all the time. I am on a shallow well. Will this hold up to heavy usage?
These little pumps our multi-stage and when used in booster situations can easily get over 80 psi. This was the wrong type of use case and the pump didn't last barely two years of constant use with heat pumps.
Well I don't have much experience with them other than this one case. I'm sure in other situations they are more widely used. The water here has lots of iron and it could have contributed to failure. Along with the fact it was used for heat pumps which can use water almost 24/7.

Have not used those before, first time I serviced a Scala2 unique situation.
Muito bom, utilizo um da marca THEBE pois em durabilidade, é o que dura por mais tempo no litoral.

How do you address it when the Scala 2 has that #5 blinking red?
Grundfos recommends using flexible pipe to connect to scala2. Else those joints would start leaking
Thanks

Hey there I have the same one the red light came on number three is that bad?
Check the owner manual online doc to see what the fault means.
I have seen a few fail recently for silly problems and just keep throwing the red code.
Ok thanks
Damn, I'm guessing you live somewhere really warm
@@jeffreyclement3564 Yes Louisiana
I have the same pressure pump but I noticed my pump take so long to build pressure, I’d say it goes on for 2-3 minutes, is this normal?
If your using water it will run continuously to keep pressure boosted. When you stop it will slow down for a few 3then turn off.
$900 pump... Only lasted two years?

How energy efficient?

What’s the max PSI you can get out of it?
These little pumps our multi-stage and when used in booster situations can easily get over 80 psi.

@@ClearWaterPumpWell ok thanks
scala is a shit pump known for failures
Well I don't have much experience with them other than this one case. I'm sure in other situations they are more widely used. The water here has lots of iron and it could have contributed to failure.

I'm sorry maybe when I get more help editing my videos.
