Teeing off Toilet Raw Water Inlet Hose for a Deck Wash Pump.

[gspeak]

I am installing a deck wash pump & was planning to tee off a raw water toilet inlet hose.

Can I just use a straight tee piece or do I have to install a Y Valve to switch from one or the other?

I have been told that if I tee below the water line that it will work fine without a Y Valve.

Thanks in advance.

I just used a Tee & works fine - it is just below the waterline.

Lazza,
Thanks for the reply. That's some serious hosing going on there. So you don't have any non-return valves on the toilet raw water side either? I just keep thinking that the wash down pump is going to suck air through the toilet.

Thanks

I'm teeing off the seacock for the toilet for my deck wash down pump. Just added a bronze tee with a swing check valve on the toilet side. Didn't want to take the chance sucking air through the anti-syphon valve or toilet.

Hey Lazza glad you are the one that has to clean all that hose and couplings Good luck Jacko PS don't let your crew down stairs if sea sick Ha

What are the different metals in the male adaptor and the tee?

You beat me to it. Looks like brass, bronze, and maybe SS or galvanized.

I see a lot of single clamping; one is OK certain places, but a few of those are BWL.

It also looks awfully new. I suspect that large clear vinyl tube is going to kink and colapse within a few months, based upon expereince; depends on if there is enough pressure to keep it open. Personally, I find it useless.

We setup our wash down pump exactly as you mentioned. Because we are using a Lavas head I put a shutoff valve in. Wash down pump on shutoff valve to head closed. Finish with wash down open valve.

Has worked great for the past 10 years.

Good luck

Thanks for that Chuck. I have since finished the instal with a simple tee off the toilet raw water hose & all is working fine. Didn't need any ball valves, though the toilet hose already had a non-return valve installed.

All good thanks.

Hose fittings below the waterline should have 2 clamps, not just one.

Using dissimilar plumbing components is not a great idea. I'd recommend an all bronze (not brass) fitting train (tee, el, hose barbs.)

Nice installation.

Dave, Glad you were smart enough not to tee off the "fat" hose...

Lazza... As mentioned a few times... you have a trifecta of not so good practices going on there... Double clamp mandatory... multiple metals and short raduis bend in the reinforced clear tubing are "grief inducers"....
