Hi all,
The strainer on the water pump is leaking occasionally so I figured I’d replace the water supply lines when I replace the strainer. While I'm at it, I'll install at least one ball valve on the intake side of the water pump per the LD Companion. The Companion article also suggests installing a braided stainless steel supply line from the tank. So I wondered if this setup makes sense: stainless line from tank to valve to strainer, then a second braided line from strainer to pump “in”. Is there a reason why I shouldn’t do it this way?
Thanks in advance!

Well, the purpose of TWO valves is to isolate the pump at both input and output for mess-free removal. If the pump inlet is higher than the top of your tank, this would be unnecessary, but one might be useful on the output. As far as using stainless braided hose on the low-pressure inlet side, I can see no rationale for that, and it might cause more noise from vibration. I have no idea why it was suggested in the article.

Consider using a Shurflo Pump Silencing Kit.
Amazon.com: SHURFLO 94-591-01 Pump Silencing Kit: Automotive (https://www.amazon.com/SHURFLO-94-591-01-Pump-Silencing-Kit/dp/B000WN5F96/ref=sr_1_1?dchild=1&keywords=SHURFLO+94-591-01&qid=1611474453&sr=8-1)
The Shurflo hose has a slight amount of flex that absorbs vibrations and noise, it works fine.
Braided hoses do not flex or give much, I prefer a softer line. Water pumps can make a lot of noise, some need all the help they can get.
