Well dear Although the best solution can be shared once the pumps or the situation is seen at the spot but there are some logical reasons which might be ignored by the user. I hope the user have gone through the user manual which includes the maintenance kit as well as maintenance schedule. Secondly the rubber rings named Bushes or WASHER in our local language are made fo rubber and they have capacity to be perform the job at certain level i.e. once the pump starts then for 2 hours in one go or 4 hours but then one has to give a break other wise if used continuously might create expansion and it will result into leakage since the seal is been deformed due to expansion.I would say first to replace the bushes at the right time secondly don't overuse it in one go and give rest so that the rubber dont get deshaped.
