Macerator noise comparison Saniflo vs Grundflos: Desperate to do the right thing!

[Leigh Florence]

Hi all

I live in a second floor flat and my toilet needs a macerator. I have bought the Grundfos Sololife 2 CWC-3 wall hung macerator 620W from Screwfix. Grundfos tell me the noise level for this pump is 70dB(A). It cost me £320.

I bought this a while ago as had to wait for the builders, so now would be difficult to return.

However, I am desperate to do right by my neighbours and want the quietest solution. My old building is like a tin can.

I see that Saniflo do a similar type to the one i want, much more expensive and i think a newer model the Sanipack Pro Up. It says the Bruit is 48dB(A). This will cost me at least £400.

I have a floating chipboard floor on top of joists. The builders tell me they are going to put some underlay down and screw the mascerator to the floor. Can they do more?

Can anyone please advise me, should i make the change. Will this make a significant difference? Are these noise ratings really comparable?

Thank you to any kind, informed person who can help me!

Leigh

Bruit ? What branch of medicine are you in?

Stick with what you`ve brought, just follow the instructions re installation.

I'm just reading what is on the website. Not in medicine.
It would really appreciate it if you could share with me why you are giving me this advice, so i can understand your thinking.

Grundfos is a good pump correctly installed and used.
To sell it you would loose money.
I don`t believe everything I read.
I`ve yet to hear the new Saniflo Up range as they are so new on the market.

Hi i've installed the Grundfos, and it runs every 5-7 hours when not in use. Can you tell me if this is expected. I called technical support and they told me it wasn't and to check the return valve (which plumber said okay), leaking appliances (toilet and shower - seem okay) and if not faulty pressure valve. Got a replacement from screwfix, installed that, does exactly the same thing. In your experience would you expect the macerator to come on a run for a few seconds periodically when not in use? Have no idea what to do now. Please help maserator expert!
