Toilet flusher/blaster modification

[Geocritter]

Back in August 2013 I noticed my toilet bowl was nearly overflowing because of a leaking bowl rinser. After taking it apart and inspecting things I felt that the parts were so flimsy I didn’t want to bother replacing them. Instead I disconnected the fresh water line that goes to the toilet bowl and connected up a kitchen-sink dish sprayer to use for flushing waste and also blasting off “skid marks” from the bowl. It works great but when I mentioned it on another RV site I got a bunch of doom & gloomers. Their complaints were.

1. You’ll get bacteria from the toilet without an anti-syphon valve. (Oh really? Just how will that happen, since the fresh water supply isn’t even hooked to the toilet anymore!).

2. Those dish sprayers aren’t meant to be under pressure all the time. Within a month or two it’ll start leaking. (That one concerned me, still it worked so well I had to continue, only I now put the spray head in the adjoining shower stall tub when not in use).

It’s been almost 2.5 years and the original $16.00 dish sprayer has yet to leak and still does a wonderful job keeping the toilet clean. In addition, I use it to occasionally clean window screens and other things in the shower stall tub.


Spraying the toilet bowl (minus any skid marks).


You can see in this photo where I spliced into the former toilet water line. I hang the hose off a hook to keep it off the floor and out of the way.


The spray head resting in the shower stall tub. The small amount of water is what was left in the spray head after I’d just used it.

I realize that this modification isn’t for everyone but even though it isn’t pretty it works far better than the original toilet flushing arrangement so I thought I'd pass it... again.

My toilet came with a sprayer........optional on several models of toilets Thetford/SeaLand. Hose end of sprayer attaches to 'stub' on the water module vacuum breaker so that water pressure is on sprayer ONLY when flushing toilet as it is downstream of toilet water inlet valve.

Reason...so that sprayer is NOT under pressure all the time.
Same way & reason that kitchen sprayers are installed..faucet has to be ON for sprayer to work.

I was probably one on other RV Forum that cautioned you about sprayer being under pressure. I know I didn't caution you about the backflow as I don't really care....it is a non-issue
Glad it hasn't leaked YET!
Just remember REASON when you find water running out of bathroom door.

Easy fix .......change it to after toilet water module.

Thank you Old-Biscuit, I'll look into the alternate hook-up you suggest. However, for now with the spray head resting safely in the shower stall tub when not in use I don't expect to see water running out under my bathroom door (like it almost did with the flimsy original equipment valve arrangement).

Which toilet brand/model?

Might be as easy as changing vacuum breaker module OR just opening 'stub' (drill bit) on existing vacuum breaker.
Lot of them have the stub but are sealed unless optional sprayer is used.

I have a Thetford, Aqua Magic Style Plus or Style II (In my owners manual they're so busy accommodating all the language options they forgot to differentiate between the two). I can see the vacuum breaker on their exploded diagram, of course it's on the backside of the toilet.

Thetford Aqua Magic Style Plus/Style II use same parts with different part numbers.

From your picture......side mounted foot pedal-----Style II (Style Plus has front foot pedal)

Optional sprayer goes on the vacuum breaker...........stub is where sprayer hose gets attached using a hose clamp---after opening up the end of stub.
