Sums it up pretty much in principle. The vibration will be transmitted outwards from where the pump is located. If not attenuated, it might be nuisance at best or the pump night be prone to "walking" or be transmitted along the piping. For that where piping is known to hit the other part of the roof support, place a small piece of anti vibration mat (cut to size) in between to shield it from this tendency.

Note: everyone upstairs might still hear the pump's soft humming when it's operating. That can't be avoided but if your plumber has done something marvellous that reduced the humming such that the only time you're aware that it's operating is when you're directly under it, do share. I want to know how also.

Where you buy the pumps they will sell else ask your plumber. Some models do provide one. Try online like AKTC or RS online which might sell.

THat would be CM5-4PM1, market rate is about RM 2100 - 2300, u can check mudah, lelong and many other sites for price reference. Ofcoz it is still possible to get slightly lower than the online prices but for budgeting, u can use them as benchmark

On and off wont cause damage to the machine? How long you have been on and off?
