i have  a pro sprayer    i use it to spray    hypo  1 to 4      then after use   flush with water   i have had it for  12 months  no problems apart from if i dont flush with water it will block with salt  deposits  badly   and it wont work so i have to   take of the pipe  then put the hole under the running garden tap  and switch  sprayer on  but thats operator error    has anyone had issues with them  i know there no good for soft washing  cant get the reach   and height  but ideal for what i do  floor spraying  do i need to   worry about  the seals or motor going running  1 to 4 mix
