Karcher k3.99m pressure washer internal leak?

you can mend it by fitting a new head on it ..but it will only last for a year or so ...i have one thats done the same i fitted a new head and seal kit last year to it ,,i think the biggest problem is that the rubber seals that are round the pistons goes hard with standing or lack of use then start to leak when you release the trigger.. if it s not a big leak or it's not squrting all over the place it may just be the pressure switch leaking a bit ..ie ..if it sits quiet for say 3-5 mins then starts and stops i would'nt be to bothered about a repair ..but if its a big leak and looseing power then my advive is to put it in a sale and buy some other make and hope for the best because they are all a bit naff for the home use market ...go to a local mechinery hire centre and hire somethink a bit more for the job then take it back and you'll have no more worries ...
