New bottom better bottle but more durable and HEAVY! A thicker bottom would make lighter and fix the problem

I've used solo sprayers commercially for 20 years, as time goes on the bottles seamed to wear quicker on bottom (thinner material?). This new base fixes that but are a lot heavier. Other issues are: the handle is made cheaper then original solid handles, and do break often. The relief valve is a joke. if tip clogs workers tend to pump the crap out of it before realizing its not pressure but tip is clogged! in heat of summer I have bottles the bottom would start rounding from excess pressure! (pressure relief valve not working)! Also when releasing pressure, the pull to release pressure easily pulls out of socket now you use plyers and eventually breaks completely. Certain springs and gaskets have to be bought in kits, increases cost somewhat. I still use these as I feel the bottles are the best on the market (and I've tried a lot of them). spray handle I rate as fair (sometimes switch out to spraying systems nozzle) as solo tend to not shut off of quickly and releasing handle slowly drops off. Spraying system is better less drip but are more a pain to rebuild.
