Hi everyone, i'v got a problem with my plumbing, No! in the house. bought an Ariston Gas water heater, but instructions not in english. We have moderate pressure comeing into the house but when it gets to the heater there is not enough pressure to get the water nice and hot. Anyone know if there is a filter in the heater. The distance from the outside waterpipe to the heater is only a few feet. Tried an on-line pump but that did not work. any ideas. :-/
