I was thinking we could use the 80 gal fresh & maybe combine the 50 or 55 for grey & black... They are only asking $50.00 dollars each, removed & delivered. Any inputs before I get back to them on these?
We fulltime and live in an RV park. This is what we have...
Our Black tank is 25(?) gallons and we dump every three days (and before any bouts of really cold weather or incoming storms... don't want to have to dump in nasty weather). The vanity sink also drains into the black tank. More water is better. We do not use any chems in our black tank. We also avoid anti bacterial soaps since they have wrecked havoc on our black tank in the past. Our grey tank is currently 42 gallons. I want to bump that up to 72 by adding another 30 gallon tank. We leave the grey tank open... let me be clearer... Because we are on full hookups and traditionally the grey tank valve is left open under those conditions, we plumbed the grey drains to completely bypass the grey tank unless we close a valve to divert the grey water into the tank. Now our fresh water is a bit different. We filter every drop of water that enters the holding tank. I have both a permanent sediment filter (no filter to replace because it is just a screen) and a Whirlpool Whole House filter housing. I run the equivalent of a Whirlpool DB-2 filter (0.5 micron). My thing is cysts must be removed. This knocks our water pressure down to a dribble. We put a stock tank float valve (valvehad same size fitting as the 1/2 inch PEX plumbing) in the 30 gallon fresh tank (Valterra ABS Rocket tank). Later this summer we will add another 30 gallon tank to give us 60 gallons. We run a ShurFlo 2088 Classic 12vDC multi-fixture water pump. This gives us good water pressure no matter what the park pressure is. We will be adding a dishwasher and a washing machine to the bus at some point. This means we will need the larger tank capacity. Due to the filters it takes a while to fill the fresh tank if it's empty. With the float valve, the tank is always full or filling and we don't have to mess with it.
We are a tad paranoid about water safety. We have been in a campground with bad water (horrible place but only $7 per week... we were desperate at the time) and we didn't drink the water (except what I boiled for 5 minutes) but the dog & cat did. Both got sick and the vintage cat never completely recovered. Based on the furkids symptoms, they were infected with Giardia Cysts
. Also we have spent a great deal of time in an area where the drinking water tended to smell/taste like the pesticides/fertilizers they used on the local crops. Are my filters overkill for city water? Probably. Will I stop using them? No! Since 2009, we have been in areas that have issued "boil water" warnings 6 times. So 6 times we were subjected to questionable water (heard about the boil warnings always too late).
Rule of thumb is that you grey tank equals or slightly exceeds your fresh tank.
