For those of you who use a Mitsubishi "EP" Series water pump, repeat, "EP" series, like the one pictured in the attachment, Do you get constant/steady water pressure?
I currently have a Mitsubishi "WP" Series water pump (came with the house). The WP series is where the pump motor sets on top of a small booster tank, but the design/operation of the WP Series pump is for the water pump to turn off and on as the pressure in its tank reaches approx 30 psi (pump turns on) and 40 psi (pump turns off). The specific psi pressures vary by tank model. While I get an "average" 35 psi water pressure, the pressure is always pulsating every second or two due to pump turning off and on which causes the water from shower heads, taps, hoses, filling up the commodes, etc., to pulsate. And with the commode tank refill you can clearly hear the pulsating. This is normal operation for Mitsubishi WP series pumps, and in fact, other manufacturers pumps based on the same design...a very common design used in Thailand.
Yes, I know I could also switch to jet-line type pump that feeds into a large pressure tank which would help reduce pulsating; instead of one or two second pulses I would have pressure changes/pulses which go up and down much slower. However, I would like to get a pump setup that gives me "constant/steady" pressure. The Mitsubishi "CP" series appears it might provide constant pressure (and looks very similar to a EP model), but it appears the CP series is designed to fill up tanks on top of a building where a separate sensor switch is needed to tell the CP pump to turn off....this really wouldn't work for my home setup...plus, I want a pump that is more self controlling.
The Mitsubishi "EP" series seems to fit that bill of steady pressure/flow with its built in "flow sensor" but since I see it also has a pressure switch build-in also which is designed to kick-in at at approx 30 to 40 psi (varies slightly by model), I'm concerned the EP may also provide pulsating water, but to a lower degree. This pressure switch may just be used as a safety feature or used under certain circumstances and the flow sensor does all the real controlling. Due to the language barrier and knowledge of the sales assistances in stores, I can't get an answer that confirms to me the pressure/volume from the EP series pump is constant/steady. So, it would be greatly appreciated from you Mitsubishi "EP" Series pump owners/users as to if your EP series pump provides "non-pulsating/steady/constant" pressure/flow. Big thanks.
