Instead of trying to argue the point with my, why don't you look it up in your own code? Here it is from the State of Virginia Plumbing Code; 802.1.6 DOMESTIC DISHWASHING MACHINES Domestic Dishwashing machines shall discharge into an airgap or air break in a standpipe or waste receptor in accordance with section 802.2, or discharge into a wye branch fitting on the tailpiece of the sink or into the dishwasher inlet connection of a food waste grinder. The waste line of a domestic dishwashing machine discharging into a sink tailpiece or food waste grinder shall connect to a deck mounted air gap or the line shall rise and be securely fastened to teh underside of the sink rim or counter. Now for your enlightenment, a wye branch on the tailpiece or a dishwasher inlet port on a food waste grinder are both indirect waste connections.

Not really the same. You plaster is going through a curing process under water with first week to month being the most critical and continuing for months to a year. The brushing is not to clean up the mess left behind by the crew (that pool should have been clean when the plaster went in). It is to help remove deposits that come to the surface in the curing process and help it cure properly. You have to do it daily at first and then weekly. I just had my pool replastered and have been testing, adjusting and brushing daily. What is included with the first 30 days service should have been specified, but I don't know of anyone who hasn't done the daily brushing themselves. If you really don't want to do it, I'm sure you could specify that, pay the additional and arrange to have someone do it for you.

The finish is undergoing a chemical reaction called hydration. It will bleed off excess no soluble calcium. This is the dust. Turn off the skimmer while brushing and for a 1/2 hour after. You don't want the excess calcium to harden on the finish or you will see splotches. The vacuum could potentially suck the plaster from the gunite. The plaster isn't strong enough to withstand the force. The finish is still soft and the wheels can leave impressions in the finish. The same is true for pool sweeps. Brushing will also help prevent stains from anything that falls in the pool. The fresh finish is at it's most susceptible. Don't miss spots repeatedly. Don't miss days. You spent how much? Yes, there should be weirs in the skimmer mouth. Your pool is an artificial life form. Consider it a newborn and treat it accordingly. Feed it correctly. Test it regularly. Scott

otisdog, Main Drain theory = suck water from the bottom and return water to the top. A little history......the first pool cleaners were top floating and pushed everything to the bottom of the pool where it would accumulate and be removed by vacuum or net. Newer pool cleaners now pick up debrey and make the need for main drains obsolete. If you are remodeling a pool and want to eliminate main drains this is fine.
