A couple of jobs i have done recently i have had severe problems with foam i have been using masive amounts of Prochem defoamer much more than suggested by prochem, but i still have this problem it's not so much foam building up in the recovery tank water level,although a small amout of foam lays on the top i empty regularly to also avoid it getting into the vacs, its foam building up in the "diffuser" or where it enters the waist tank thats the problem it builds up so much that vac performance is affected, also worried that this may damage the vacs, today i had to stop four times on one room, even after vaccing up defoamer through the hoses twice
, now i read the instruction manual on my Airflex and it said because of higher vac strength foaming will be more of a problem than it would on a twin vac machine, which i might add i never had this problem once, but its getting to the point that i thought i cant do this it's going to damage my machine, how on earth do i get around this, are there some chemicals that i can put in my prespray/ solution tank that can reduce foam what is going on
The first time it happend i was using ultrapac renovate and clear water rinse, and today Nemesis and clear water, the lady in the house today said she had used vanish but only on a stain, i was so desperate today that i mixed up some defoamer and sprayed it on the carpet before extraction which helped a bit, after i finished i took the cover of the waste tank and ran the vacs to try and dry them just in case but i think this is going to be expensive if this keeps happening
