ignis Posted November 25, 2020 Share Posted November 25, 2020 2003 bought MITSUBISHI 150w Automatic Water Pump Since then had it serviced twice. New diaframe + rings etc It was never very high pressure just OK 2 story house Yesterday started on/off all the time when running water and very low pressure, tried bleeding but no better, No leaks anywhere but the pressure tank looks a bit rusty.. As I have to cut the pipes to take it to repair workshop, is it better to buy a new one ? how long do they last ? 17 years service is not bad. If I have to buy a new one what make ? MITSUBISHI again or HITACHI ? would there be more pressure with a 250w.. both appear about the same price Any advice please Link to comment Share on other sites More sharing options...

Popular Post bankruatsteve Posted November 25, 2020 Popular Post Share Posted November 25, 2020 (edited) I am very happy with my Hitachi 250W "constant pressure" pump (going on 8 years). I think 250W is the best size for 2 story home. Edit: When replacing the pump, use unions. Then no need to cut PVC next time remove for repair/replace.
