We offer an installation and replacement service in Dublin for all types of shower booster pumps. The difference between positive and negative head pumps is determined by whether the header tank is above or below the outlet point. If the header tank is above, you have a positive head and if it is below the outlet, you have a negative head. Positive head pumps are mostly used in houses and negative head pumps tend to be most common in apartments. Our installers have a no fix, no fee policy. When choosing a pump the rated pressure should be factored in i.e. installing a 3 bar shower booster pump next to the hot water cylinder in the airing cupboard will be too much. We would recommend installing a Showermate Eco 2.0 bar pump. If you need your Monsoon Standard Twin U2.0 Bar, S2.0 Bar Twin, S3.0 Bar Twin and S4.0 Bar Twin or your Stuart Turner Showermate Replaced in Dublin call our office on 01-4458543
