Pros: Direct replacement for Mira pump but at quarter of the price!

Cons: None

This shower pump was easily fitted in minutes (replacing old Mira unit).It feeds two showers, provides adequate water pressure & is not too noisy - good purchase.

5/ 5

Pros: 'Kicks in' at very low flow rate., Very quiet.

Cons: None noted.

An aging Mira pump was replaced by this Grundfos. Performance of the Grundfos is excellent and it is so, so quiet compared with it's predecessor.
Delivery was prompt. Installation was straightforward and well covered in accompanying instructions.
I really cannot see there being a better pump for the money involved.

5/ 5

Pros: Durable, Easy to install, Looks good, Value for money, Well Made

Cons: Anti-vibration feet can easily detach themselves from the pump body during installation, This is annoying, why can't they be lightly glued in place?

I needed to replace my 11 year old Watermill PR50-D pump. This pump was still fully operational with no loss of performance. However it buzzed loudly when it initially kicked in (indicating the bearings were on their way out) and also when running, sounded like a bag of nails.
The replacement Grundfos STR 1.5 C pump was practically identical to the old Watermill PR50-D pump and the installation of the replacement pump took me only 30 minutes including air purging and testing.
The Grundfos STR 1.5 C pump is a top class, high quality product with excellent installation instructions and accessories. The packaging was also superb. Top marks to Grundfos.

Pros: Very quiet. Excellent price

Cons: Maybe slightly less pressure than previous aura 45

Found you online. Excellent price and really quick delivery. Pump much quieter than my previous aura45. Similar performance albeit maybe slightly less pressure from shower - but hardly noticeable. Overall very pleased.

5/ 5

Pros: East to fit , Quiet to run

Cons: Can't find any!

I am really impressed with this pump from Grundfos. Fitted a thermostatic shower on a gravity fed system, and it barely produced a trickle. Fitted the pump in no time at all, and now have an effective shower. Surprised how quiet it is, although I did mount the pump on a small concrete block, and used silicone to anchor the block to the airing cupboard floor. Would recommend to anyone.

5/ 5

Pros: Was very easy to fit as it was a direct replacvcent to the watermill pump

Cons: Maybe a small water bund for it to sit into to carch any water that might leak in the future?

The best booster pump so far, it is so much quieter than the watermill one it replaced
Obviously Grundfoss have may many improvements to make it quiet
The pump was excellent value for meny even compared to the original I purchased 4 years ago
Delivery was excellent as it arrived exactly on time within the 1 hour slot
